Abstract:

The primary producers of pulses are small-scale farmers with small and dispersed plots under rain-fed conditions with substantially lower yields of less than 0.9 t/ha as compared to the improved faba bean varieties and international yields. There are many biotic and abiotic factors which hampers faba bean production in Ethiopia. From biotic factors chocolate spot (Botrytis fabae Sard.) is the major fungal disease hampering faba bean production in Ethiopia.). It is a highly prevalent and destructive disease, causing yield loss up to 61% on a susceptible and 34% on tolerant faba bean genotypes in the central highlands. But we can manage this economically important disease in manner which comprises all available diseases management methods in combination that is IPM (Integrated Pest management). So, the objective of this review work was to review available integrated pest management option for management of chocolate spot disease of faba bean in Ethiopia. We can control the disease by using different methods from these late sowing of faba bean, mixed cropping of faba bean with cereal crops and mancozeb spray reduced the disease and increased the grain yield and seed weight over sole and mixed cropping with field pea; also cereal mixing with faba bean has advantages over faba bean mixing with field pea. Suppressive effects can be ascribed to a combination of host biomass reduction, altered microclimate and physical barriers to spore dispersal. Also creation of a physical barrier in the form of non-host plants prevents some of the dispersed spores from being deposited on the host tissue by interception. In Ethiopia, study has revealed that the biological control agents for chocolate spot of faba bean and Bacilli are natural residents of faba bean leaves. Additionally recommendation have been given that, further study has to be done to explore the mode of action by bacillus subtilis against fabae.

Abstract:

Isolates of Ascochyta fabae from faba bean (Vicia faba) and A. lentis from lentil (Lens culinaris) collected from different countries were used in this study. The Didymella teleomorph (sexual state) of each fungus was induced to develop and mature on inoculated sterile lentil stems. Both fungi were heterothallic, with two mating types, designated MAT1-1 and MAT1-2. When certain isolates of A. fabae and A. lentis were crossed, hybrid pseudothecia developed. Growth, sporulation, colony appearance, morphology, and pathogenicity of the hybrid progeny frequently differed greatly from the parent isolates. Inoculations with single-ascospore progeny from matings among compatible isolates of A. fabae caused disease in faba bean but not in lentil; inoculations with single-ascospore progeny from matings among compatible isolates of A. lentis incited disease in lentil but not in faba bean. Inoculations with single-ascospore progeny from crosses between faba bean and lentil isolates did not induce disease in either host. Asci from crosses between A. fabae and A. lentis mostly contained fewer than eight ascospores that were, on average, larger than those from eight-spored asci. Matings among certain isolates of A. fabae resulted in production of pseudothecia with ascospores considerably larger than is typical for D. fabae. Random amplified polymorphic DNA (RAPD) banding patterns of Ascochyta isolates from faba bean and lentil are clearly different, and banding patterns from hybrid progeny from crosses between A. fabae and A. lentis confirmed hybridity. RAPD markers proved useful in supporting identifications of ascospore isolates from faba bean to known Ascochyta species. Dendrogram analysis indicated similarity between the two fungal species was low. The pathogenicity tests, morphological characteristics, and RAPD markers indicate that A. fabae and A. lentis represent distinct taxa. D. lentis, with its anamorph, A. lentis, is proposed as a new species that is distinct from D. fabae, with its anamorph, A. fabae.

Abstract:

The stick tea thrip Dendrothrips minowai (Priesner) (Thysanoptera: Thripidae) is a destructive pest in tea plantations in south and southwest China. To control this pest, a non-crop banker plant system was developed using a polyphagous predator Orius strigicollis (Poppius) (Heteroptera: Anthocoridae) with the black bean aphid Aphis fabae (Scopoli) (Hemiptera: Aphididae) as an alternative prey and the faba bean Vicia faba as the banker plant to support the predator in targeting the pest. The fitness of A. fabae on tea plants and faba bean was evaluated to determine its host specificity. Moreover, the control efficacy of the banker plant system on D. minowai on tea plants was tested in the laboratory and compared with that of direct release of O. strigicollis. The experiments showed that faba bean was an excellent non-crop host for A. fabae because, while the aphid population increased quickly on faba bean, it could only survive for up to 9 days on tea plants. Compared with direct release of O. strigicollis, lower densities of pest were observed when introducing the banker plant system. Our results indicate that this banker plant system has the potential to be implemented in the field to improve the control of the pest thrips.

Abstract:

The Black bean aphid Aphis fabae Scopoli (Homoptera: Aphididae) is a serious pest of faba bean, Vicia faba L. (Fabaceae) in Algeria. The use of resistant cultivars may reduce the impact of this pest on broad bean production and at the same time reduce environmental risks and control costs. The level of resistance of fourteen cultivars of broad bean, Vicia faba was screened in the field against the main aphid pest of faba bean, the Black bean aphid, Aphis fabae Scopoli during January to April 2011 in Biskra region (in the east of Algeria). Among the cultivars tested, six cultivars (1, 9, 12, 13, 14 and 15) were the most resistant in the three counts, while three cultivars (4, 6 and 11) were showed a high susceptibility against this aphid at least once. The remainder of cultivars (3, 5, 7, 8 and 10) revealed an unsettled level of resistance. The relationship between the level of resistance and morphological characters of cultivars indicated that the resistant cultivars have a longer leaflet than the high susceptible cultivars. In the other hand, the statistical analysis showed that no significant differences on the plant height and the leaflet width in the tow category of cultivars (resistant and high susceptible).

Abstract:

Ascochyta blight, caused by Ascochyta fabae Speg., is a common and destructive disease of faba bean (Vicia faba L.) in the Middle East, Europe, Canada, New Zealand (4), and Australia. The main sources of inoculum are debris and seeds from which spores are air- and splashborne. The teleomorph of A. fabae has been reported previously only from England (2). The presence of the teleomorph supports the variability reported in the fungus populations from Canada (3) and Poland (1). Stems of faba bean plants, severely infected with A. fabae, were collected in July 1999 from Tel Hadya, Syria. The plants previously had been inoculated with a mixture of isolates of the pathogen, collected from the main faba bean-growing regions in Syria between 1996 and 1998, and kept under shade. The infested stems were used to inoculate the ICARDA Faba Bean Ascochyta Nursery planted on 29 November 1999. During late January 2000, symptoms appeared on the susceptible faba bean genotype. Stem pieces from debris used for inoculations were collected from the field and examined microscopically for the presence of ascomata. The maximum, minimum, and mean temperatures and rainfall at Tel Hadya during December 1999 were 16.5, 5.8, and 8.7°C and 22.4 mm, respectively. There were 16 nights when temperatures dropped below 0°C, and 10 nights when temperatures were between 0 and 5°C. Ascomata of A. fabae ranged from 76 to 209 μm wide (average 158 ± 3.9 μm) and 101 to 285 μm in length (average 178 ± 4.1 μm). Asci were 10 to 15 μm wide (average 14 ± 0.3 μm) and 51 to 96 μm long (average 63 ± 1.1 μm). Ascospores were 5 to 8 μm wide (average 7 ± 0.2 μm) and 15 to 20 μm in length (average 17 ± 0.3 μm). These measurements are comparable to those reported from England. Individual ascomata were dissected from stem tissue and fixed to the lids of petri dishes containing 2% water agar. After 24 h, the petri dishes were examined microscopically to locate ascospores on the surface of the medium. Germinating ascospores and developing colonies were transferred from water agar to faba bean dextrose agar. Colonies characteristic of A. fabae developed on the latter medium within 7 days of incubation at 20 ± 2°C. Pathogenicity tests of developing colonies were carried out on 3-week-old faba bean plants (Giza 4) using a spore suspension (2.5 × 105 spores per ml) of each of the isolates. Both inoculated seedlings and control seedlings inoculated with sterile water were covered with plastic bags for 48 h in a plastic house maintained at 18 ± 2°C. After removal of the plastic bags, seedlings were wetted four times per day by spraying with tap water to runoff. Inoculated plants showed characteristic symptoms of Ascochyta blight 15 days after inoculation. The fungus was reisolated from lesions that developed on leaflets of all inoculated seedlings, but not from any of the control seedlings. This is the first report of the occurrence of A. fabae, the sexual stage of Didymella fabae Jellis & Punithalingam in Syria, and indicates that the fungus could develop population variants. These findings have implications for breeding for resistance to Ascochyta blight. References: (1) A. Filipowicz. Faba Bean Abstr. 4:47, 1983. (2) G. J. Jellis and E. Punithalingam.

AbstractHere we review the potential of ILB 938 (IG 12132 – doi: 10.18730/60FD2), a unique faba bean accession originating from the Andean region of Colombia and Ecuador, maintained at ICARDA – International Center for Agricultural Research in the Dry Areas, with resistance to multiple biotic and abiotic stresses and carrying some useful morphological markers. It has been used as a donor of leaf-related drought adaptation traits and chocolate spot (Botrytis fabae) resistance genes in faba bean breeding programmes worldwide. From generated populations of recombinant inbred lines, quantitative traits loci associated with these useful traits have been mapped. Other markers, such as a lack of stipule-spot pigmentation and clinging pod wall, show the presence of unusual changes in biochemical pathways that may have economic value in the future.

Abstract:

A collection of 267 accessions belonging to 61 Vicia species other than V. faba was screened under growth chamber conditions for response to Ascochyta fabae and Uromyces viciae-fabae, causal agents of ascochyta blight and faba bean rust, respectively. High resistance to both diseases was very frequently detected in Vicia spp. in contrast to the high susceptibility previously reported in most V. faba accessions. Most of the Vicia spp. accessions studied here were very resistant or even immune to A. fabae with only one per cent of the accessions allowing development of small lesions bearing pycnidia. High resistance or immunity to U. viciae-fabae was also frequently found in the collection, with only ten per cent of the accessions showing compatible interaction although with reduced disease severity. These findings reinforce the specificity of A. fabae and U. viciae-fabae and clarify the potential role of cultivated and wild Vicia spp. in the epidemiology of these faba bean diseases.

Abstract:

Field studies were conducted in 1983 and 1984 to assess the effect of rust (Uromyces viciae-fabae) on the yield components, pods per plant, seed per plant, seed per pod, total dry matter and harvest index of two faba bean (Vicia faba) cultivars and one susceptible line. The effect of rust was assessed also on the yield of 14 slow-rusting populations of V. faba. Rust epidemics were created by artificial inoculation and healthy control plots were protected from rust by fungicide applications. Rust severity remained low in the cultivars Diana and Herz Freya and seed yield of each cultivar was reduced by 3.8–6.6% and 6.3–9.7% in 1983 and 1984, respectively. Rust became severe in the susceptible line 2N40 and significantly reduced some yield components and thereby yields by 67.9% and 49.5% in 1983 and 1984, respectively. Rust caused yield losses of only 1–2% in the slow-rusting population 2N43, of 1–11% in slow-rusting populations from Erfordia and Diana, and of 6–43% in other slow-rusting populations, indicating that some slow-rusting populations are more tolerant to rust than others.

To ascertain the role and mechanism of cinnamic acid in the process of soil-borne Fusarium wilt infection with fava bean, we studied the effect of cinnamic acid on the faba bean and Fusarium oxysporum f. fabae (FOF). Our results showed that cinnamic acid treatment affected the physiological resistance of faba bean to FOF after inoculation with the pathogen and enhanced the pathogenicity of the pathogen, which may have led to aggravation of infection by the pathogen and increases in the incidence rates of Fusarium wilt and disease.

Abstract:

The faba bean (Vicia faba) is a temperate grain legume, that is regaining interest due to the high demand for food and feed uses and the environmental services provided. The parasitic weed broomrape (Orobanche crenata) appears as the major constraint to agricultural production in the Mediterranean Basin. The yield stability can be managed by adjusting agronomic practices and breeding for adaptation. In this study, we compared the performance of three susceptible faba bean accessions with that of eight lines previously selected for their broomrape resistance, in multi-environment field trials. Results confirmed that the grain yield in the region was negatively affected, mainly by broomrape infection, followed at a distance by ascochyta blight (Ascochyta fabae), whereas the grain yield was little affected by the low occurring levels of chocolate spot infection (Botrytis fabae). The yield was favored by rain at flowering and was reduced by low temperatures at pre-flowering and flowering, and by high temperatures at flowering and grain-filling. The combined ANOVA showed significant effects of the genotype, environment, and genotypex environment interaction. The weighted average of the absolute scores biplot (WAASB), a heat map with 21 scenarios based on the WAASB ratio and the multi-trait stability index (MTSI) were utilized to determine the mean performance and stability of the faba bean genotypes. Quijote, Navio6, Baraca and FaraonSC are proposed as ideal lines for cultivation in the region and to be further used in future breeding programs.

Abstract:

In 2003−2005 faba bean accessions were evaluated in laboratory and field inoculation tests with a mixture of differently virulent isolates for susceptibility to anthracnose caused by the fungus Ascochyta fabae Speg. All tested commercial faba bean cultivars, both colour and white flowering, were found to be susceptible or highly susceptible. The highest level of resistance was found only in declared sources of resistance: 29H, L-8 and Petra. Segregation of F2 plants derived from the cross of cultivar Merlin (susceptible, white flowering) with line Petra (resistant, colour flowering) was observed. The plants were moderately susceptible to highly susceptible. This finding indicates a multigenic character of resistance. Repeated selection cycles with the selection of resistant plants in F2 and F3 generations were performed. In the F4 generation, colour flowering lines with a high level of resistance, nearly at the same level as in line Petra, were obtained. In comparison with the parental cultivar Merlin an increase in the resistance of selected white flowering lines was proved. Resistance will be increased/stabilized in further repeated selection cycles.

Abstract:

The diploid cool-season legume species, faba bean (Vicia faba L.), is one of the vital pulses for the people in the world as it maintains the sustainability of agriculture and provides nutrient-rich grains. Biotic and abiotic stresses are, however, challenging the faba bean production in many countries. The foliar diseases of faba bean are among the major constraints for the production and productivity of faba bean. Recently, a new foliar disease “Faba bean gall” caused by plant debris and soil-borne pathogen (Olpidium viciae K.) is rapidly spreading and causing high yield losses in Ethiopia. This review paper presents the distribution, impact, epidemiology, and biology of faba bean gall pathogen and principally illustrates how the application and investigation of the various diseases’ management approaches such as avoiding crop residues, crop rotation, intercropping, use of elicitors to induce host resistance, use of resistant genotypes, bioagents, compost teas, plant extracts, and lastly use of chemical fungicides could be important to control the faba bean gall disease underlying in faba bean.

Abstract:

Effects on penetration and hypersensitive resistance of the cinnamyl acid dehydrogenase (CAD) suicide inhibitor ([(2-hydroxyphenyl) amino] sulphinyl) acetic acid, 1.1 dimethyl ester, which suppresses phenylpro-panoid biosynthesis, and of D-mannose, which sequesters phosphate and reduces energy available in host cells, were studied in faba bean (Vicia faba) genotypes with differing resistance mechanisms to faba bean rust (Uromyces viciae-fabae). Inhibition of CAD reduced penetration resistance in lines 2N-34, 2N-52, V-1271, and V-1272, revealing an important role for phenylpropanoid biosynthesis in the resistance of these lines. Inhibition of CAD also inhibited hypersensitive cell death in these lines. D-mannose had little or no effect on resistance. By contrast, CAD inhibition did not affect penetration resistance of line BPL-261, which has a high degree of penetration resistance not associated with hypersensitive cell death. In BPL-261, D-mannose inhibited penetration resistance. The parallelism between the faba bean genotype responses to rust observed here and the response of barley genotypes with differing resistance mechanisms to powdery mildew after similar inhibitor treatments is analyzed and discussed.

Abstract:

The effects of raw faba bean (Vicia faba L., minor) meal (VFM) and its fractions on the growth and nitrogen utilization of rats have been determined in two experiments. Two commercial varieties of VFM were tested, local VFM (409–439 g/kg diet) and Troy VFM (439 g/kg diet). The bean fractions tested were V. faba lectin-depleted protein (VFDP), V. faba lectin (VFL) and V. faba cotyledon residue (VFCR). All diets were supplemented with amino acids to target requirements. Body-weight, body N and lipid contents of rats fed on VFM were reduced significantly in comparison with control rats fed on lactalbumin. This was due, in part, to the lower digestibility of the protein, lipid and dry matter (DM) of VFM diets. As a result, net protein utilization (NPU) and biological value (BV) of faba bean proteins were less than expected. Urine and urea-N outputs of the VFM-fed rats were also elevated in both experiments. Increasing the energy content of local VFM diets led to significantly higher dry body-weight, body N and lipid contents, with the result that the NPU and BV values of the protein also increased. However, the NPU values for VFM-fed rats were still significantly lower than those for the controls in both experiments. In contrast, true N, lipid and DM digestibilities in rats given local VFM were not significantly affected by the difference in the energy content of the diets. The replacement of two-thirds of the lactalbumin in the diet with VFDP (65 g/kg) reduced dry body-weight, N and lipid contents, NPU and BV compared with the control rats, even though N, lipid and DM digestibilities were not significantly different. The nutritional performance of rats fed on lactalbumin-based diets containing 7 g VFL/kg was similar to that of the controls. Similarly, the inclusion of the cotyledon residue (237 g VFCR/kg diet) had no appreciable effect on any of the variables studied. As VFL and VFCR had no antinutritional effects in these rats, it appears that the low nutritional value of VFM for rats (NPU 0.66) results not only from the low digestibility of the bean proteins, but also from disturbances in N metabolism.

Abstract:

SUMMARYA 2-year field study was conducted in central Greece (Larissa) and was repeated simultaneously in northern Greece (Thessaloniki) to determine the productivity and the competitive ability against corn poppy (Papaver rhoeas L.) of six faba bean (Vicia faba L.)-barley (Hordeum vulgare L.) intercrops grown at three seeding ratios (75:25, 50:50 or 25:75% of the recommended seeding rates) and two crop arrangements (alternate or mixed rows). Faba bean and barley sole crops were also included. Corn poppy dry weights in barley sole crop or faba bean-barley intercrops were 83 to 85% or 50 to 99%, respectively, lower than that in faba bean sole crop. Total dry matter (DM) and total crude protein (CP) yields of faba bean-barley intercrops were, in most cases, not significantly affected by corn poppy competition. The results obtained in both locations indicated that intercropping faba bean with barley could be an alternative practice to that of faba bean sole crop in sustainable production systems, because of its greater productivity, balanced nutritive value and competitiveness against aggressive weeds such as corn poppy.

Abstract:

Chocolate spot, which is caused by the necrotrophic fungus Botrytis fabae, is a major foliar disease occurring worldwide and dramatically reducing crop yields in faba bean (Vicia faba). Although chemical control of this disease is an option, it has serious economic and environmental drawbacks that make resistant cultivars a more sensible choice. The molecular mechanisms behind the defense against B. fabae are poorly understood. In this work, we studied the leave proteome in two faba bean genotypes that respond differently to B. fabae in order to expand the available knowledge on such mechanisms. For this purpose, we used two-dimensional gel electrophoresis (2DE) in combination with Matrix-Assisted Laser Desorption/Ionization (MALDI-TOF/TOF). Univariate statistical analysis of the gels revealed 194 differential protein spots, 102 of which were identified by mass spectrometry. Most of the spots belonged to proteins in the energy and primary metabolism, degradation, redox or response to stress functional groups. The MS results were validated with assays of protease activity in gels. Overall, they suggest that the two genotypes may respond to B. fabae with a different PSII protein repair cycle mechanism in the chloroplast. The differences in resistance to B. fabae may be the result of a metabolic imbalance in the susceptible genotype and of a more efficient chloroplast detoxification system in the resistant genotype at the early stages of infection.

In vivo grafting experiments were conducted to determine their potential for improving pulse crop breeding techniques for pea, faba bean and lentil. Four scion×five rootstock genotype combinations were used for pea. Survival of grafted pea scions was not affected by genotype of scions or rootstocks, even for wild subspecies. Some scion-rootstock combinations resulted in reduced flowering time for scions. Total seed production of rootstock regrowth plus grafted scion was greater than for ungrafted controls or rooted cuttings. For faba bean, four scion×four rootstock combinations showed scion-rootstock interaction affected percent survival and flowering time of grafted scions. In vivo grafting of lentil scions to faba bean rootstocks is reported for the first time. Two lentil genotypes were grafted onto four faba bean rootstocks. The effects of lentil scion and faba bean rootstock genotype were significant for percent survival, but not for seed production. Percent scion survival was 85% for pea, 56% for faba bean, and 55% for lentil scions on faba bean rootstocks. In vivo grafting techniques can help to maximize the size of F2 populations for breeding and genetic studies. Intergeneric in vivo grafting of lentil onto faba bean rootstock could be useful for interspecific hybridization studies for lentil.

Abstract:

Experiments involving the intercropping faba bean with each of lupin, fenugreek and Egyptian clover as well as growing faba bean alone were carried out at Assiut University on a farm naturally infested with Orobanche in two seasons. The major objective of the study was to investigate the effect of different intercropping combinations with faba bean on the infestation with Orobanche. The results obtained revealed that intercropping faba bean with each of lupin, fenugreek and Egyptian clover markedly reduced the Orobanche crenata Forsk infestation of faba bean. the number of branches, the height of the first pod, the number of pods, the seed yield and the number and dry weight of Orobanche spikes were significantly affected by the intercropping treatments, but these had no significant influence on plant height, straw yield or 100-seed weight. intercropping faba bean with each of lupin, fenugreek and Egyptian clover increased the faba bean seed yield, consequently the economic return was also increased.

Abstract:

Lactic acid fermentation could be used as a potential modification tool for faba bean flour to enable its incorporation in boosting the nutritional profile of gluten-free breads. Gluten-free breads made with fermented or unfermented faba bean flours were compared with commercial soy flour. The amounts of faba- and soy-bean flours were adjusted to obtain the same protein content in bread (16%). Both fermented and unfermented faba bean flour resulted in larger bread volume (2.1 mL/g and 2.4 mL/g, respectively) compared to bread made with soybean flour (1.5 mL/g). Breads made with unfermented and fermented faba flour had higher porosity (82% and 72%, respectively) than bread with soy flour (61%). The faba breads also were softer than the soy bread. Fermentation of faba flour prior to bread making significantly increased crumb hardness (584 vs. 817 g). Fermentation increased in vitro protein digestibility (72.3% vs. 64.8%). Essential Amino Acid and Biological Value indexes were significantly higher for breads containing fermented faba flour compared to breads made with unfermented faba and soy flour. The Protein Efficiency Ratio and Nutritional Index increased by fermentation from 33 to 36 and 1.6 to 2.7, respectively. Pre-fermentation of faba bean flour improved the nutritional properties of high-protein, gluten-free faba bread. A sensory panel indicated that fermentation did not affect the crumbliness, evenness of pore size and springiness of breadcrumb.

Abstract:

The nutrient profile of zero-tannin faba bean and its effects on performance and carcass characteristics of grower-finisher pigs was investigated. In exp. 1, chemical characteristics were analyzed. Faba bean contained (as fed) 27.5% crude protein (CP), 1.75% lysine, 0.88% threonine, and 0.21% methionine. Twelve 55-kg barrows were fitted with an ileal cannula and fed twice daily at 3 x maintenance either a 96% faba bean diet or a 62% faba bean diet containing cornstarch to measure apparent total tract energy and ileal amino acid (AA) digestibility, respectively, and calculate standardized ileal digestible (SID) AA and net energy (NE) content. After a 6-d acclimation, faeces were collected for 2 d and ileal digesta for 2 d. Apparent total tract energy digestibility, and digestible energy and NE content were 88.5%, and 3.47 and 2.27 Mcal kg-1 (as fed), respectively. Apparent ileal digestibility was 85.9, 76.1, and 74.1%, and SID AA content was 1.54, 0.70, and 0.16% (as fed), for lysine, threonine, and methionine, respectively. In exp. 2, 100 grower pigs in 20 pens were fed either a soybean or faba bean-based diet regimenfrom 35 to 115 kg. Diets were formulated to equal NE and SID [Grower (35 to 60 kg), 2.40/3.95; Finisher 1 (60 to 90 kg), gilts 2.38/3.15, barrows 2.38/2.76; Finisher 2 (90 to 115 kg), gilts 2.38/2.92, barrows 2.35/2.55; Mcal kg-1 NE/g SID lysine Mcal-1 NE, respectively] using determined NE and SID values for faba bean. Pigs were weighed, feed intake was measured, and carcass measurements were obtained. From 35 to 115 kg, average daily feed intake (ADFI; 2.58 and 2.56 kg d-1, respectively) and gain (0.96 and 0.98 kg d-1) did not differ between faba bean and soybean meal. Feed efficiency was 0.02 higher for soybean meal than for faba bean in the Grower phase (P < 0.05). At slaughter, back fat thickness did not differ; however, loin depth was 4.0 mm thicker for soybean meal than for faba bean (P < 0.05). In summary, zero-tannin faba bean has an attractive nutrient profile and does not alter ADFI or average daily gain (ADG) of grower-finisher pigs at inclusion rates up to 30%.The reduced feed efficiency in the Grower phase and reduced lean thickness for pigs fed faba bean indicate that dietary AA supply might have been limiting for the faba bean diets early in the study. In conclusion, the zero-tannin faba bean is a worthwhile energy and protein feedstuff to consider in swine feed formulation.

Abstract:

The effects on faecal mineral excretion of two commercial varieties (local cultivar and Troy cultivar) of raw faba beans (Vicia faba L., minor) meal (VFM) and its fractions have been studied in growing rats. Diets contained local-VFM (dark seed coat) and Troy-VFM (light seed coat) at 474–500 g/kg diet, hull (VFH) from both varieties at 65 g/kg diet, and the insoluble cotyledon residue (VFCR) obtained from the Troy variety at 237 g/kg diet. Rats were pair-fed on diets which had been supplemented with amino acids to target requirements and contained similar amounts of zinc, manganese, iron and copper. With VFM diets the apparent absorption of Zn and Mn was significantly reduced. On the other hand, with hulls the apparent absorption of Fe was reduced while that of Cu slightly increased. As the amounts of calcium, phosphorus and magnesium in VFM and VFH diets were higher than in the controls, the increased intake resulted in a significant increase in both the apparent absorption and the faecal excretion of these minerals. The inclusion of VFCR in the diet had no significant effect on the mineral content of faeces. The relatively low concentrations of phytate in the bean seeds of 7.8 and 6.7 g/kg for the local and Troy cultivars respectively, could not adequately account for the increased mineral excretion. The results suggest that other seed constituents, possibly the soluble non-starch polysaccharides, may be involved in the elevated loss of Zn and Mn in rats fed on diets containing faba bean for extended periods, while some insoluble structural hull components may interfere with the absorption of Fe from the gut.Faba bean (Vicia faba): Faecal mineral excretion: Rat.

Abstract:

The faba bean plant (Vicia faba L.) is one of the world’s most important legume crops and can be infected with various viral diseases that affect its production. One of the more significant viruses in terms of economic impact is bean yellow mosaic virus (BYMV). The current study used the molecularly identified Rhizobium leguminosarum bv. viciae strain 33504-Borg1, a nitrogen-fixing bacteria, to biosynthesize silver nanoparticles (AgNPs) to control BYMV disease in faba bean plants. Scanning electron microscopy (SEM), a particle size analyzer (PSA) with dynamic light scattering (DLS), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR) were used to characterize the prepared AgNPs. The DLS, SEM, and TEM analyses revealed that the AgNPs were spherical and rough, with sizes ranging from 13.7 to 40 nm. The FTIR analysis recognized various functional groups related to AgNP capping and stability. Under greenhouse conditions, spraying faba bean leaves with the AgNPs (100 µg/mL) 24 h before BYMV inoculation induced plant resistance and reduced plant disease severity and virus concentration levels. Contrarily, the AgNP treatment enhanced plant health by raising photosynthetic rates, increasing the fresh and dry weight of the faba bean plants, and increasing other measured metrics to levels comparable to healthy controls. Antioxidant enzymes (peroxidase and polyphenol oxidase) inhibited the development of BYMV in the faba bean plants treated with the AgNPs. The AgNPs decreased oxidative stress markers (H2O2 and MDA) in the faba bean plants. The plants treated with the AgNPs showed higher expression levels of PR-1 and HQT than the control plants. The study findings could be used to develop a simple, low-cost, and environmentally friendly method of protecting the faba bean plant from BYMV.

Proteins were extracted from urediospores of the bean rust fungus (Uromyces phaseoli var. typica: two isolates), of the cowpea rust fungus (U. phaseoli var. vignae; two isolates), and of the faba bean rust fungus (U. viciae-fabae; one isolate) and separated by two-dimensional isoelectric focusing – polyacrylamide gel electrophoresis under denaturing conditions. The two isolates of the cowpea rust fungus had identical polypeptide patterns; the two isolates of the bean rust fungus differed by 19 polypeptides. The polypeptide patterns of the bean rust, cowpea rust, and faba bean rust fungi differed markedly from each other. There were 277 polypeptides detected in extracts of the faba bean rust fungus, while more than 335 polypeptides were detected in extracts of each isolate of the other two fungi. While U. phaseoli var. typica and U. phaseoli var. vignae shared 183 polypeptides, U. viciae-fabae had only 149 and 146 polypeptides, respectively, in common with the other two rust fungi. This is consistent with the view that the two varieties of U. phaseoli are more closely related to each other than to U. viciae-fabae. However, when all detected polypeptides were compared, the differences between the two varieties were as extensive as those found between species. It is suggested, therefore, that the designation, by some mycologists of the cowpea rust fungus as a separate species, U. vignae, is correct.

Abstract:

Faba bean (Vicia faba) is an ancient legume species known for its high protein content. The usage and consumption of the faba bean is limited by a glycoside, vicine-convicine (VC). Consumption of VC causes haemolytic anemia in individuals with the genetic condition called favism. Faba beans with low VC concentration are opening the possibility of reduction of favism disease, but there are many challenges in analyzing VC concentration. The objective of this study was to develop expressed sequence tag (EST) markers that can differentiate between low VC content (LVC) and high VC content (HVC) faba bean genotypes. Three single nucleotide polymorphisms (SNPs) were discovered that distinguished between LVC and HVC genotypes. The SNPs were validated using Kompetitive Allele Specific PCR (KASP) and mass spectrometry phenotyping. Molecular marker SNP 316 (Intron of Medtr2g009270 at 1,851,012 bp) was the most successful marker in differentiating between LVC, HVC, and heterozygous faba bean genotypes. This marker has applications in seed selection and acceleration of breeding programs, which is the first step towards allowing all consumers concerned with the effects of favism to enjoy the nutritional value of faba bean.

The diversity and phylogeny of 30 rhizobia isolated from nodules of faba bean plants grown on 5 geographic regions located in the East Azerbaijan province of Iran were examined using rep-PCR fingerprinting, sequence analysis of 16S rRNA accompanied with nodC genes. Based on cluster analysis of rep-PCR fingerprints, faba bean rhizobia isolates were differentiated into five clusters (A to E) at 80% similarity level. The cophenetic correlation coefficient for the dendrogram obtained from the combined dataset of BOX and ERIC primers was 0.942. The percentage of polymorphic loci was 59.2% using the BOX-PCR primer and 67.3% using the ERIC-PCR primers. The data obtained by rep-PCR fingerprinting showed high apparent correlation between genetic diversity and geographical origin of the isolates. The phylogenetic analysis based on 16S rRNA and nodC sequences showed that representative isolates were closely related to R. leguminosarum bv. viciae and R. fabae. To the best of our knowledge, this is first report of isolation and characterization of R. fabae from Iran.

Abstract:

Faba bean (Vicia faba Roth) and pea (Pisum sativum L.) are grown worldwide as protein sources for food and feed and can be used as cover crops after wheat (Triticum aestivum L.). However, faba bean is underutilized in upper Midwest farming systems. This study was conducted to determine how faba bean relates to pea as a forage, cover crop, and in cycling of nutrients to maize (Zea mays L.) in the following season. Five faba bean cultivars and two pea cultivars, a forage pea and a field pea, were established after wheat harvest in North Dakota, in 2017 and 2018. Faba bean and pea cultivars averaged 1.3 Mg ha−1 of biomass, enough to support 1.5 animal unit month (AUM) ha−1 for a 450 kg cow (Bos taurus L.) with calf, at 50% harvest efficiency. Crude protein content was highest in faba bean cv. Boxer (304 g kg−1), with faba bean cv. Laura and forage pea cv. Arvika having similar content, and field pea having the least (264 g kg−1). Cover crop treatments did not affect maize in the following year, indicating no nutrient cycling from faba bean and pea to maize. Both cover crop species tested provided high protein forage, suitable for late grazing, with a more fibrous crop residue. Faba bean has potential as a cover crop in the upper Midwest while providing greater quality forage than pea.

Abstract:

Faba bean (Vicia faba L.) is an important cool-season legume crop that ranks fourth after chickpea (Cicer arietinum L.), field pea (Pisum sativum L.) and lentil (Lens culinaris L.) in terms of total production. The global production of faba bean was 4.8 Mt in 2017, with China, Ethiopia and Australia being the largest producers (1.8, 0.93 and 0.37 Mt, respectively). However, its area of production is not increasing relative to other crops, mainly because of high yield instability. This can be attributed to several factors related to plant traits (e.g. phenology, morpho-physiology) and biotic and abiotic stresses. Faba bean has a very poor flower:pod ratio, with a maximum 20% of flowers resulting in pods. Environmental stresses such as frost, heat and drought cause significant damage to flowers and young pods; therefore, matching phenology of crops to the environment is important for avoiding or minimising detrimental effects of unfavourable environmental conditions. In order to improve adaptation and yield, we need to understand the main factors affecting plant growth, including biotic stresses, identify the main yield components, and find traits associated with tolerance to frost, heat and drought.

Abstract:

Faba bean (Vicia faba L.) is an important grain legume with high protein content (approximately 25–30%) and high nutritional value. It is broadly cultivated in temperate areas both for human consumption and as animal feed. According to FAOSTAT (2020), the total cultivated area of faba bean reached approximately 2.5 million ha, yielding more than 4.5 million tons. The characterization of the genetic diversity in faba bean is an important parameter for genetic and biodiversity studies, germplasm characterization, and for introducing genetic variability in plant breeding. The present study aims to assess the genetic diversity among 53 Greek, varied faba bean populations provided by the Hellenic Agricultural Organization “DEMETER” seed bank. To determine the genetic diversity of the studied populations, six SCoT DNA markers were used. A total of 114 loci were obtained with 37.95% being polymorphic and 62.05% monomorphic within or between populations. SCoT markers are a useful tool for the detection of genetic diversity among faba bean populations and encourage targeted crossing strategies. The present study is the first step towards the development of an efficient breeding program.

Abstract:

Mixed cropping of teff (Eragrostis tef) with faba bean (Vicia faba) was compared with sole cropping in the 2002 and 2003 growing seasons at Holetta Research Centre, in the central highlands of Ethiopia. The treatments were sole teff (25 kg seed ha−1), sole faba bean (200 kg seed ha−1) and 12.5, 25, 37.5, 50 and 62.5 % of the sole seed rate of faba bean mixed with a full teff seed rate. A randomized complete block design replicated four times was used. Treatment effects were significant for seed and biomass yields of each crop species. Increasing the seed rate of faba bean in teff/faba bean mixture increased faba bean seed yield but decreased teff grain yield. Nonetheless, mixed cropping of faba bean with teff increased land use efficiency and gave higher total yields compared to growing either species in sole culture. Teff yield equivalent, land equivalent ratios (LERs) and system productivity index (SPI) of the mixtures exceeded those of sole crops especially when the seed rate of faba bean in the mixture was increased to 50 kg ha−1 (25 %) or more. The relatively high crowding coefficient values indicated yield advantages from mixed cropping of the two species. The highest values of teff yield equivalent, LER and SPI were obtained when faba bean was mixed at a rate of 62.5 % with the full seed rate of teff. We suggest that, at the current prices of the respective crops, up to 62.5 % of faba bean can be mixed in normal teff to get better total yield and income than sole culture of either species.

Abstract:

The nutritional value of zero-tannin (ZT) faba bean for starter pigs is poorly characterized. Five mash diets containing 0, 10, 20, 30 or 40% ZT faba bean in substitution for soybean meal were fed to 75 pens of 5-wk-old pigs for 21 d. Increasing the dietary level of ZT faba bean did not affect average daily weight gain, feed intake or feed efficiency (P > 0.05) for each weekly period and the entire study (days 0 to 21). Increasing the dietary level of ZT faba bean linearly increased apparent total tract digestibility of crude protein and P (P < 0.05), but not of dry matter, gross energy and Ca (P > 0.05). In conclusion, young pigs can be fed up to 40% raw, ground ZT faba bean (var. Snowbird) in full substitution for soybean meal in the starter diet.Key words: Digestibility, faba bean, growth performance, soybean meal, starter pig
