Resumo:

A composição química e a qualidade biológica da torta de colza obtida da semente, variedade CTC-4, foram determinados. A farinha foi preparada me diante prensagem da semente e extração da gordura com solvente, lixiviada durante 2 horas, com água corrente na proporção de 1:5, e agitação constante, a fim de reduzir os níveis de glicosinolatos. O efeito tóxico foi observado através do peso dos órgãos e da histopatologia dos órgãos em experimento de 60 dias. A qualidade biológica da torta desintoxicada, ao nível de 5% e 10%, foi semelhante ao da caseína (PER controle 3,18 vs 3,08, 5% e 2,98, 10%). O PER da torta crua foi de 2,28. Os ratos que receberam a farinha crua tiveram órgãos maiores. As tireóides dos ratos submetidos as dietas 2 e 3, não demonstraram alterações que suspeitassem de um efeito bociogênico e as alterações ocorridas nas tireóides dos animais que receberam, D-4 foram semelhantes àquelas ocorridas nos grupos 2 e 3. Não houve danos célulares graves em relação ao fígado, os rins, o coração, baço e supra-renais para todos os grupos observados. O método de extração dos fatores tóxicos da colza foi eficiente de acordo com os resultados obtidos para o presente estudo.

Resumo:

A canola (Brassica napus L. var oleífera) é uma oleaginosa, pertencente à família Brassicaceae, resultado do cruzamento interespecífico entre repolho silvestre (Brassica oleracea L.) e mostarda (Brassica rapa L., syn. campestris). O boro é considerado um micronutriente, que atua na translocação de açúcares, formação de proteínas, crescimento do tubo polínico, germinação dos grãos de pólen, desenvolvimento das sementes e das paredes celulares. O objetivo desta pesquisa foi estudar as interferências nos componentes produtivos de dois híbridos de canola com a aplicação de adubação com boro por via foliar. Para tanto, instalou-se um experimento em condições de campo num delineamento experimental de blocos ao acaso em arranjo fatorial 2 x 3. Utilizou-se os híbridos Hyola 433 e Hyola 575 CL e três doses de boro foliar (0;100; 200) g ha-1 de B. As seguintes características foram avaliadas: número de plantas, número de síliquas por planta, massa de parte aérea, massa de 100 grãos e produtividade. Com a aplicação de boro houve aumento da massa de grãos independente do híbrido. Para produtividade houve aumento somente para o híbrido Hyola 433, sendo a maior produtividade alcançada na dose de 200 g ha-1. O híbrido Hyola 575 CL não teve sua produtividade alterada com a aplicação de boro. Palavras-chave: ácido bórico; Brassica napus L. var. oleífera; colza; massa de 100 grãos; oleaginosa. Leaf boron fertilization in two rapessed ABSTRACT: Rapessed (Brassica napus L. var oleífera) is an oilseed, belongs to Brassicaceae family, resultated between inter specific crossing of wild cabbage (Brassica oleracea L.) and mustard (Brassica rapa L., syn. campestris). Boron is considered a micronutrient, acting in sugars translocation, protein formation, pollen tube growth, pollen grain germination, seeds and cell wall development. The aimed was to study the interferences in productive components of two rapessed hybrids with application of boron fertilization by leaf application. For this, a field experiment was installed by using experimental design of randomized blocks in a 2 x 3 factorial scheme. Hyola 433 and Hyola 575CL hybrids and three doses of leaf boron (0; 100 and 200) g ha-1 of B were used. The following characteristics were evaluated: plants number, number of pods per plant, mass of one hundred grains and yield. With boron application there was an increase in grain mass independent of the hybrid. In relation grain yield there was increase only for Hyola 433 hybrid, with the highest yield reached at 200 g ha-1. The Hyola 575CL hybrid did not have its productivity altered with the application of boron. Keywords: boric acid; Brassica napus L. var. oleífera; mustard; mass of a hundred grass; oilseeds.

Se analizaron dos poblaciones M3 de colza derivadas de las variedades Target y Pachuca (Brassica napus y B. campestris) irradiadas con Co60, con el objeto de detectar plantas con alto contenido de aceite y bajo contenido de ácido erúcico, así como determinar la influencia de las radiaciones ionizantes sobre estos componentes. Se encontraron coeficientes de variación altos para el contenido de aceite en las variedades Target y Pachuca irradiadas, coñ relación a los testigos no irradiados; se detectaron también plantas con altos y bajos contenidos de ácido erúcico en las irradiadas; estos resultados se atribuyen a la presencia de mutaciones causadas por las radiaciones. El comportamiento observado en las poblaciones irradiadas para el contenido de ácido linoleico y el peso de semilla por planta fue semejante al de las poblaciones no irradiadas.

The effect of increasing NaCl concentrations up to 170 mM on the lipid composition of leaf membranes was studied on rape (Brassica napus L. var. oleifera Metzg) in hydroponic culture for one month. At NaCl concentrations lower than 102 mM, the polar glycerolipid biosynthesis was stimulated. NaCl concentrations higher than 102 mM reduced the contents in total lipids, monogalactosyldiacylglycerol, digalactosyldiacylglycerol, and phospholipids. In contrast, the neutral lipid contents increased with increasing NaCl concentration. An increase in NaCl induced a decrease in linolenic and hexadecatrienoic acid contents and an increase in linoleic and palmitic acid contents in all lipid groups. Key words: rape, lipids, sodium chloride.

Resumo:

Straw mulch cover is one of the most important soil erosion control measures applied to reduce runoff and soil loss in cultivated areas. However, in developing countries such as Iran, without a clear tradition or knowledge about soil erosion control measures, the use of straw mulch is rare, and its impact in the most extended crops is not well understood. We investigated the separate and combined effects of colza (Brassica napus L.) and corn (Zea mays L.), to mitigate the activation of soil loss and runoff in sandy-loam soils, under different antecedent soil moisture conditions, in a rainfed plot in Northern Iran. Under laboratory conditions, we used a rainfall simulator device. The experiments were performed by using a rainfall intensity of 50 mm h−1, with a duration of 10 min and an inclination of 30%, with three replications. These conditions were used to evaluate the soils under extreme meteorological and topographical conditions. Two types of straw mulch, colza and corn, separated and combined with three different cover levels (25, 50 and 75%) and four distinct antecedent soil moisture conditions (0, 15, 20 and 30%), were used. The results showed that the applied straw mulches had significant effects on the reduction of soil loss and sediment concentration, by almost 99%. The maximum reduction of soil loss and sediment concentration was observed for the treatments with 0% moisture and 75% of corn, colza + corn and colza, with a reduction of 93.8, 92.2 and 84.9% for soil loss, respectively, and 91.1, 85.7 and, 60.7% for sediment concentration, respectively. The maximum reduction of runoff was also obtained with 0% soil moisture and a cover of 75%, reducing 62.5, 48.5 and 34.8% for colza, colza + corn and corn, respectively. The corn straw mulch showed the highest effectivity on reducing soil loss and sediment concentration toward colza treatment. But the colza straw mulch showed the best results on reducing runoff toward corn treatment. We conclude that the application of straw mulch is affordable and useful in reducing soil loss and runoff, instead of bare soils.

Se evaluó el efecto de cuatro edades de cosecha (90, 120, 150 y 180 días) sobre el rendimiento de biomasa aérea y composición química de la colza, así como su uso como suplemento henificado para vacas lecheras en pastoreo a 3279 msnm. El rendimiento forrajero y la composición química se evalúo en 16 parcelas, 4 por tratamiento, de acuerdo con un diseño de bloques completos al azar. La biomasa de colza cosechada fue henificada y picada a 1 cm de longitud, suministrada diariamente a razón de 3 kg por vaca. Dieciséis vacas Holstein cruzadas y multíparas se distribuyeron en cuatro tratamientos que consistieron en henos elaborados de acuerdo con la edad de cosecha. La producción de leche por vaca se registró durante seis semanas. Los sólidos totales, grasa, proteína y lactosa se determinaron en la última semana del estudio. A medida que la edad de la colza fue mayor se incrementó la biomasa forrajera y la fibra detergente neutra (FDN), y disminuyó la concentración de proteína cruda; sin embargo, la producción de leche y sus componentes lácteos no se vieron afectados por la suplementación de los cuatro tipos de heno, con excepción del heno de colza cosechada a 90 días de edad, que incrementó el contenido de proteína láctea.

The use of technologies is increasingly present in agriculture. The seed coating is one of these technologies. However, to obtain it, it’s demanded the use of machines and technics which are restricted to production companies, burdening the price on this type of product. Given the above, it was aimed to develop and evaluate a prototype capable of coating small seeds. To elaborate the conceptual design of the prototype it was employed the computer program for modeling 3D SketchUp, version 2014. The prototype measures were expressed in millimeters (mm). The prototype has three main parts: (1) support base, (2) seed coating bowl, and (3) cementing material container. To evaluate the prototype, bentonite, gypsum and kaolin were used as filling materials of the colza seed (Brassica napus L.). As cementing material the PVA glue was used in the percentages of 20, 30, 40 and 50%. The studied variables were prototype yield, production cost of the coated seeds and residue generated in the coating process. The prototype has a compact size, answering the needs of laboratory and/or small producer. It presented cost and residues in an acceptable level and yield up to 88%.

Abstract The purpose of the research was a comparative evaluation of the disease affection of spring and winter forms of Brassica napus and Brassica juncea on the central zone of the Krasnodar region. Phytosanitary monitoring of diseases was carried out from the seedling stage. In 2011-2020, there were identified the diseases affecting winter and spring crops Brassica napus and Brassica juncea to the same extent: the occurrence frequency of downy mildew and powdery mildew was high, of Alternaria blight – from medium to high, of phytoplasma and bacterial blight – low. Differences are established for Sclerotinia disease, Phoma rot, Fusarium blight, white rust, gray rot. The occurrence frequency of Sclerotinia disease on winter form of Brassica napus and Brassica juncea varied in research years from low to medium, of Phoma rot – from medium to high; on spring forms, these diseases were noted in certain years with the low frequency. Fusarium blight affected only sowings of spring forms of Brassica napus and Brassica juncea with medium and high frequency, except for 2018-2019, when it was low. White rust affected only spring from of Brassica napus, gray rot – only winter forms of Brassica napus and Brassica juncea in certain years with the low frequency.

Brassica napus and B. rapa are native to Eurasia. In Canada, these species are commonly referred to as volunteer canola, while feral populations of B. rapa are referred to as birdrape. Brassica napus and B. rapa have been grown commercially for their seed oil content in western Canada since the middle of the last century and volunteer populations are common in fields. Escaped populations of both species are also found along roadways, railways and in waste areas; however, only B. rapa is known to have naturalized, self-sustaining feral populations in these habitats in eastern Canada. Despite these escaped and feral populations, B. napus and B. rapa are mainly a concern in agricultural fields where their combined relative abundance has increased over the past few decades. In the mid 1990s, herbicide-resistant genotypes of B. napus were released for commercial production. Herbicide-resistance and the stacking of genes in volunteer populations conferring resistance to multiple herbicides have contributed to increased difficulties in controlling volunteer B. napus in some crops. However, yield loss resulting from volunteer populations is not well documented in Canada.

Brassica is the second-largest oilseed crop after Soybean. The total production of Brassica in the overall world is 71 million tons. In Pakistan, its total production per unit area is very low. Biotic and abiotic stresses mainly affect the brassica crop. In agriculture, shattering is the dispersal of crops seeds before their ripening. The pod wall shatters and breaks apart when it loses its hydration and cells split in a dehiscence zone organized at a suture between the edge of the lignified pod and the vascular tissue replum. The degeneration of middle lamella and loss of cellular cohesion in the dehiscence zone are the main reasons for pod shattering and seed losses. Grain yield losses in Brassica vary from 10 to 25 percent due to shattering. More than 400 kg has-1 or 12% seed losses can be occurred due to pod shattering under unfavorable conditions. Insect pest and disease damage also accelerate ripening and pod shattering. The main breeding techniques for developing rapeseed grain yield potential are a good knowledge and application of the morphological, physiological, and genetic basis of grain yield. Modern technologies, such as embryo rescue, marker-assisted breeding, and novel variation (mutation), may make it much simpler to introduce new rapeseed types having shattering tolerance than traditional methods. Thus, an overview of anatomical and physiological aspects and genetics of shattering is presented in the context of recent advances in molecular genetics and several agronomic managements to avoid shattering in Brassica.

Resumo:

The diversity of inflorescence architecture in angiosperms relates to attracting pollinators and allowing the effective dispersal of seeds. Molecular understanding of the genetic factors regulating inflorescence architecture from the model system of Arabidopsis could provide critical insights for addressing this developmental process/pathway in a closely related crop species like Brassica napus L. Towards this objective, we have isolated and characterized the orthologs of the homeobox gene BREVIPEDICELLUS (BP) in three Brassica species, B. napus (BnBP), Brassica rapa L. (BrBP), and Brassica oleracea L. (BoBP). These Brassica orthologs show a high degree of conservation at the nucleotide and amino acid level, including the homeodomain and the intron positions. The B. napus ortholog complemented the Arabidopsis bp null allele and overexpression of BnBP in B. napus transgenic lines resulted in altered leaf phenotypes. Together, these results suggest that Brassica BP genes are functional orthologs of Arabidopsis BP. Ectopic expression of AS2, a negative regulator of BP encoding a LOB domain transcription factor, in transgenic B. napus produced compact inflorescence architecture reminiscent of the loss-of-function bp mutant phenotype described previously in Arabidopsis. These results provide evidence in support of BP as a potential target gene for modifying inflorescence architecture in Brassica crop species.

The worldwide climate changes every year due to global warming, waterlogging, drought, salinity, pests, and pathogens, impeding crop productivity. Brassica napus is one of the most important oil crops in the world, and rapeseed oil is considered one of the most health-beneficial edible vegetable oils. Recently, miRNAs have been found and confirmed to control the expression of targets under disruptive environmental conditions. The mechanism is through the formation of the silencing complex that mediates post-transcriptional gene silencing, which pairs the target mRNA and target cleavage and/or translation inhibition. However, the functional role of miRNAs and targets in B. napus is still not clarified. This review focuses on the current knowledge of miRNAs concerning development regulation and biotic and abiotic stress responses in B. napus. Moreover, more strategies for miRNA manipulation in plants are discussed, along with future perspectives, and the enormous amount of transcriptome data available provides cues for miRNA functions in B. napus. Finally, the construction of the miRNA regulatory network can lead to the significant development of climate change-tolerant B. napus through miRNA manipulation.

Environmental abiotic stresses limit plant growth, development, and reproduction. This study aims to reveal the response of Brassica napus to salt stress. Here, transcriptomics, metabolomics, and proteomics analysis were performed on 15 Brassica napus leave samples treated with salt at different times. Through functional enrichment analyzing the differentially expressed genes (DEGs), differential metabolites (DMs) and differentially expressed proteins (DEPs), the key factors that dominate Brassica napus response to salt stress were identified. The results showed that the two key hormones responding to salt stress were Abscisic acid (ABA) and jasmonic acid (JA). Salt stress for 24h is an important milestone. Brassica napus adjusted multiple pathways at 24h to avoid over-response to salt stress and cause energy consumption. The increased expression in BnPP2C is tangible evidence. In response to salt stress, JA and ABA work together to reduce the damage caused by salt stress in Brassica napus. The increased expression of all BnJAZs after salt stress highlighted the function of JA that cannot be ignored responding to salt stress. In addition, some metabolites, such as N-acetyl-5-hydroxytryptamine, L-Cysteine and L-(+)-Arginine, play a critical role in maintaining the balance of ROS. Proteins like catalase-3, cysteine desulfurase, HSP90 and P450_97A3 were the most critical differential proteins in response to salt stress. These findings of this study provide data support for Brassica napus breeding.

AbstractThe oviposition preferences of Lygus lineolaris (Palisot de Beauvois) were studied on Brassica carinata A. Braun, Brassica juncea (L.) Czern, Brassica napus L., Brassica rapa L., Sinapis alba L. (high glucosinolates), Sinapis alba L. (low glucosinolates), and Sinapis arvensis L. in a choice test during a 14-day period in field cages. Host-plant discrimination occurred on at least two levels. The first level occurred at the generic level; ovipositing females first selected species of Sinapis on which to lay eggs and later laid on species of Brassica. On species of Sinapis, 80% or more of the total number of eggs were laid during days 1–6, whereas only 35–58% were laid during this period on species of Brassica. The second level occurred at the species level in both Brassica and Sinapis. In Brassica, significantly more eggs were laid on B. carinata and B. napus than on B. juncea; in Sinapis, significantly more eggs were laid on S. alba (high glucosinolates) than on S. arvensis. The numbers of eggs did not differ significantly among B. carinata, B. napus, and S. alba (high glucosinolates). The numbers of eggs on B. rapa and S. alba (low glucosinolate) were not significantly different from those on the other five Brassica and Sinapis hosts tested. Host-plant selection seemed to be unaffected by glucosinolate levels in the seed of S. alba.

Can. J. Plant Sci. 91: 889–896. Increased demand for biodiesel feedstock has encouraged greater napus canola (Brassica napus L.) production, but there may be a need for greater production of other oilseed crops for this purpose. A multi-site field study was conducted to determine the oil yield potential of various crops relative to that of napus canola in the semi-arid, short-season environment of the Canadian prairies. Oilseed crops evaluated included rapa canola (Brassica rapa L.), juncea canola (Brassica juncea L.), Ethiopian mustard (Brassica carinata L.), oriental mustard (Brassica juncea L.), yellow mustard (Sinapis alba L.), camelina (Camelina sativa L.), flax (Linum usitatissimum L.), and soybean [Glycine max (L.) Max.]. Crop emergence and growth were generally good for all crops, but soybean did not fully mature at some locations. The number of site-years (out of a total of 9) that crops attained similar or greater yields compared to napus canola were camelina (6), oriental mustard (5), juncea canola (3), flax (3), soybean (3), rapa canola (2), yellow mustard (2), and Ethiopian mustard (1). The ranking of seed oil concentration was napus canola=rapa canola= juncea canola=flax>camelina=oriental mustard>Ethiopian mustard>yellow mustard>soybean. Considering yield and oil concentration, the alternative oilseed crops exhibiting the most potential for biodiesel feedstock were camelina, flax, rapa canola and oriental mustard. Oils of all crops were easily converted to biodiesel and quality analyses indicated that all crops would be suitable for biodiesel feedstock with the addition of antioxidants that are routinely utilized in biodiesel fuels.

Two types of monosomic plants of Brassica napus L. were discovered among the backcross progenies of crosses between Diplotaxis muralis L. and B. napus and between Brassica juncea L. and B. napus. These monosomics were designated mono-1 and mono-2, respectively. Morphologically the monosomic plants were virtually indistinguishable from their sib disomic plants. Seed production on both mono-1 and mono-2 plants was normal. Cytological examination revealed that most pollen mother cells (85%) of mono-1 plants formed 18 bivalents plus one univalent at diakinesis, while the remainder (15%) formed 17 bivalents plus a trivalent. The univaltn in mono-1 was submetacentric and its two arms were always stained more lightly than the centromeric region. Later meiotic stages in mono-1 plants appeared normal. The plants of mono-1 produced two types of pollen grains which were different in size. Both the large and small pollen grains of mono-1 were deeply stained with an I2–KI solution. Meiotic behavior of mono-2 plants was similar to that of mono-1 plants, but the frequency of trivalent formation was higher (62%). The univalent in mono-2 was longer than the two chromosomes it paired with to form a trivalent. Pollen produced on mono-2 plants was uniform in size and comparable to that of the normal disomics.Key words: Brassica napus, Brassica juncea, Diplotaxis muralis, aneuploidy, monosomics.

The genetic control of seed glucosinolate content in oilseed rape was investigated using two intervarietal backcross populations. Four QTLs segregating in the population derived from a Brassica napus L.'Victor' × Brassica napus L.'Tapidor' cross, together accounting for 76% of the phenotypic variation, were mapped. Three of these loci also appeared to control the accumulation of seed glucosinolates in a Brassica napus L. 'Bienvenu' × 'Tapidor' cross, and accounted for 86% of the phenotypic variation. The three QTLs common to both populations mapped to homoeologous regions of the B. napus genome, suggesting that seed glucosinolate accumulation is controlled by duplicate genes. It was possible to extend the comparative analysis of QTLs controlling seed glucosinolate accumulation by aligning the published genetic maps generated by several research groups. This comparative mapping demonstrated that high-glucosinolate varieties often carry low-glucosinolate alleles at one or more of the loci controlling seed glucosinolate accumulation.Key words: backcross, comparative mapping, genetic linkage map, marker-assisted breeding, QTL.

The β-amylase (BAM) gene family, known for their property of catalytic ability to hydrolyze starch to maltose units, has been recognized to play critical roles in metabolism and gene regulation. To date, BAM genes have not been characterized in oil crops. In this study, the genome-wide survey revealed the identification of 30 BnaBAM genes in Brassica napus L. (B. napus L.), 11 BraBAM genes in Brassica rapa L. (B. rapa L.), and 20 BoBAM genes in Brassica oleracea L. (B. oleracea L.), which were divided into four subfamilies according to the sequence similarity and phylogenetic relationships. All the BAM genes identified in the allotetraploid genome of B. napus, as well as two parental-related species (B. rapa and B. oleracea), were analyzed for the gene structures, chromosomal distribution and collinearity. The sequence alignment of the core glucosyl-hydrolase domains was further applied, demonstrating six candidate β-amylase (BnaBAM1, BnaBAM3.1-3.4 and BnaBAM5) and 25 β-amylase-like proteins. The current results also showed that 30 BnaBAMs, 11 BraBAMs and 17 BoBAMs exhibited uneven distribution on chromosomes of Brassica L. crops. The similar structural compositions of BAM genes in the same subfamily suggested that they were relatively conserved. Abiotic stresses pose one of the significant constraints to plant growth and productivity worldwide. Thus, the responsiveness of BnaBAM genes under abiotic stresses was analyzed in B. napus. The expression patterns revealed a stress-responsive behaviour of all members, of which BnaBAM3s were more prominent. These differential expression patterns suggested an intricate regulation of BnaBAMs elicited by environmental stimuli. Altogether, the present study provides first insights into the BAM gene family of Brassica crops, which lays the foundation for investigating the roles of stress-responsive BnaBAM candidates in B. napus.

The wall-associated kinase family contributes to plant cell elongation and pathogen recognition. Nine Cruciferous species were studied for identification and molecular evolution of the WAK gene family. Firstly, 178 WAK genes were identified. A phylogenetic tree was constructed of the Cruciferous WAK proteins into four categories, of which the Brassica rapa, Brassica oleracea and Brassica napus genes in the U’s triangle were more closely related. The WAK gene family was unevenly distributed in B. napus chromosomal imaging, with the largest number of BnWAK genes located on chromosome C08. In the expression analysis, the expression patterns of the WAK gene family varied under different stress treatments, and some members of BnWAKs were significantly different under stress treatments. This study lays a foundation for further revealing the functional mechanisms of the WAK gene family in Brassica napus.

Construction of Brassica napus (2n = 38) and Lesquerella fendleri (2n = 12) karyotypes revealed that B. napus contains 10 pairs of metacentric, 5 pairs of submetacentric, and 4 pairs of subtelocentric chromosomes, while L. fendleri contains 6 pairs of metacentric chromosomes that are, on average, 1.5 times longer than those of B. napus. By analysing the karyotypes and performing genomic in situ hybridization (GISH), the chromosome complements of somatic hybrids produced between Brassica napus (+) Lesquerella fendleri were studied. Protoplasts fused with no pretreatment, symmetric fusions, resulted in hybrids containing L. fendleri chromosomes in numbers varying from 2 chromosomes to 2 chromosome complements. In the asymmetric fusion experiments, in which L. fendleri protoplasts were irradiated before fusion, plants with from 38 to more than 76 chromosomes were obtained. In the hybrids with 38 chromosomes, the presence of L. fendleri chromosomes was not detected by GISH analysis, even though L. fendleri DNA was revealed by Southern blotting. Intra- and inter-genomic recombinations were observed in hybrids from both symmetric and asymmetric fusions. The rearrangements were more prevalent in plants resulting from asymmetric fusions. Modifications of the phenotype and reduced fertility of the hybrid plants were correlated with increased dosages of the L. fendleri genome. At least one genome complement of L. fendleri was required to express its morphological features.Key words: Agrobacterium rhizogenes transformed root cultures, Brassica napus, Lesquerella fendleri, somatic hybrids, chromosome translocation.

A Brassica napus L. crop called nabicol traditionally has been grown by farmers in northwestern Spain for many years and is an important horticultural product during the winter season. The relationship of nabicol to other B. napus crops has been studied based on simple sequence repeat (SSR) data. However, molecular and morphologic classifications often disagree. The objectives of this research were to study the morphologic and agronomic relationships of nabicol landraces to other B. napus crops and to compare those relationships with the ones already known, based on SSR data. Thirty-five B. napus populations from different geographic origins and uses were evaluated. Data were recorded on 17 morphologic and agronomic traits. Principal component analysis and cluster analysis were performed to classify the populations. Eight principal components (94% of the total variability) were standardized to produce the Mahalanobis' generalized distances, and a cluster analysis was conducted using the unweighted pair group method with arithmetic averages. There are no major differences between B. napus var. pabularia (DC.) Rchb. (nabicol, couve-nabiça, forage rape) and B. napus var. oleifera DC. (oilseed rape), and they probably share a common origin. Rape kale (B. napus var. pabularia) and rutabaga [B. napus var. napobrassica (L.) Rchb.] cultivars are separated from the rest and probably they have an independent origin or domestication. Molecular and morphologic classifications are complementary, and both are necessary to classify germplasm correctly and to clarify genetic relationships among B. napus crops.

Twenty five polyhaploid plants (2n = 2x = 19, genome formula AC) of Brassica napus (2n = 4x = 38, AACC) were cytogenetically studied. Seven of these were found among field populations and the rest were derived through anther culture of B. napus cv. Regent. Meiotic behaviour at diakinesis and metaphase I revealed nine bivalents and one univalent in more than 40% of the more than 400 pollen mother cells analyzed. However, when the chromosome number of the polyhaploids was doubled using colchicine, 19 bivalents were observed. These doubled plants (2n = 4x = 38, AACC) also had normal behaviour identical to a regular B. napus at other meiotic stages. Quadrivalent associations were observed when the chromosome numbers were doubled to the octaploid level (2n = 8x = 72, AAAACCCC). It is suggested that A and C are homoeologous genomes. If homologous partners are present, chromosomes would pair within the same genome to form bivalents as occurred in the allotetraploids and to form quadrivalents as occurred in the allooctaploids. However, when a homologous partner is not available, the homoeologous chromosomes would then pair to form bivalents in those polyhaploids.Key words: Brassica napus, polyhaploids, genome relationship, meiotic behaviour, homoeologous pairing.

In the present study, the response of primary attributes (seedling growth, percent emergence, seedling fresh and dry biomass, and seedling moisture contents) and nutrient contents (Calcium, Magneisum, Iron, Manganese, Zinc, Copper) of Brassica napus L. was evaluated as a function of glucose-induced priming and salinity. The priming comprised 30 minutes, 60 minutes and 90 minutes of seeds soaking in glucose solution (0.50 M) and salinity stress was simulated by the solutions of 0, 15, 18, 21, and 24 milli Molar (mM) NaCl. The results revealed that doses of salinity induced significant changes in the fresh weight of Brassica napus L. The response of selected nutrients (except Magnesium) as a function of salinity was also highly significant (P≤0.05 %). The salinity doses reduced plants' mineral contents (except Mn) compared to control. The priming of seeds for 90 minutes significantly (P≤0.05 %) enhanced certain early growth traits (plumule growth, radical growth, fresh weight and dry weight) of Brassica napus. On the other hand, for improving germination (%) and moisture contents (%) of Brassica napus, soaking durations of 30 minutes and 60 minutes are more suitable. The pre-soaking of seeds for 60 minutes increased the Calcium, Magnesium and Manganese contents (mg/litre) of Brassica napus. The Iron and Zinc contents (mg/litre) showed hype in seedlings raised from seeds primed for 30 minutes. The priming of seeds for 90 minutes was found to be stimulatory for Copper (mg/litre) only. The influence of factors interaction (treatments × priming durations) on the initial growth attributes and the studied minerals of Brassica napus L. was highly significant (P≤0.05 %). From the gathered evidence, the present study concludes glucose as a potent priming agent that can boost oil-yielding plants' performance under saline conditions.
