Annotation:

La leyenda troyana se configura como relato literario a lo largo de la Antigüedad expandiendo y modificando los diferentes episodios que la componen. El estudio de la utilización de la leyenda en los poemas conservados del puño y letra de Dioscoro de Afrodito, autor del siglo VI, nos permiten aproximarnos a la evolución y configuración del canon troyano, así como a las obras clásicas todavía disponibles en su época y al resto de fuentes que le sirvieron como modelo para sus composiciones.The Trojan legend becomes a literary narrative throughout Antiquity expanding and modifying its different episodes. The study of this legend in Dioscorus of Aphrodito’s autograph poems (from 6th century BC), allows us to grasp the evolution and configuration of the Trojan canon, the classical works still available in his time, and other sources used as a model for his compositions.

Annotation:

AbstractThe neglected area of later Greek syntax is explored here with reference to the future optative. This form of the verb first appeared early in the classical age but virtually disappeared during the Hellenistic era. Under the influence of Atticism it reappeared in later literary texts, and this paper is concerned largely with its revival in late legal and epistolary texts on papyrus from Egypt. It is used mainly in set legal phrases of remote future conditions, but we also see it in letters to express wishes (again, largely formulaic) for the future, both of which uses are foreign to Attic Greek. Finally, the future optative's appearance in conjugations on grammatical papyri from Egypt is used to demonstrate the form's presence in education even at the end of the classical world there, with the archive of Dioscorus of Aphrodito uniquely showing both this theoretical knowledge of it and examples of its application in legal documents.

Sommaire : Augustin est connu pour son esprit de service qui le porte à produire des écrits en réponse aux requêtes d’amis, de connaissances ou même de personnes étrangères qui sollicitent son aide. En 410, il reçoit une lettre (ep. 117) de Carthage, de la part de Dioscorus, jeune homme d’origine grecque, qui lui envoie de nombreuses questions sur les dialogues de Cicéron. Sa recherche est motivée par la crainte de paraître ignorant devant ceux qui lui poseraient des questions sur ces sujets de retour dans sa patrie. Augustin saisit l’occasion pour le détourner des ambitions de la vaine gloire et lui montre, en exposant sa connaissance des écoles philosophiques antiques, qu’il ne sert à rien de s’imbiber des opinions des philosophes quand on ne recherche pas dans l’humilité la vérité elle-même. Cet article présente et analyse l’exposé d’Augustin des théories et des contradictions de ces philosophies antiques, et montre les recours aux références bibliques presque inaperçues présentes dans la lettre.

В данном исследовании рассматривается церковная политика императора Василиска (475–476) и предлагается богословский анализ его указа под названием «Энциклика», которая стала первым официальным имперским документом, направленным против Халкидонского Собора (451) и его учения о двух природах во Христе после воплощения. «Энциклика» ставит Халкидонский Собор вне церковной традиции, противопоставляя его трём предыдущим Вселенским Соборам. На этом фоне даётся анализ седьмого правила Ефесского Собора (431), позиции Диоскора Александрийского и сопутствующих исторических событий. This study examines the church policy of Emperor Basilisk (475–476) and offers a theological analysis of his decree entitled «Encyclical», which became the first official imperial document directed against the Council of Chalcedon (451) and his doctrine of the two natures in Christ after the incarnation. The «Encyclical» places the Council of Chalcedon outside the church tradition, contrasting it with the Three previous Ecumenical Councils. Against this background, the analysis of the seventh rule of the Council of Ephesus (431), the position of Dioscorus of Alexandria and the accompanying historical events is given.

Abstract The threefold summons of an absent defendant in the context of synodal proceedings – which had been admittedly formed by influence from the respective process in Roman law – is an important component of the ecclesiastical judicial procedure. In this paper I examine in detail all the extensive narratives of threefold summonses preserved in conciliar acts of the fifth and sixth centuries, that is, the cases of Nestorius of Constantinople and John of Antioch at the council of Ephesus (431), the case of the archimandrite Eutyches at the Resident Synod of Constantinople (448), the case of Athanasius of Perrhe at the local synods of Hierapolis (early 440s) and Antioch (445) as well as at the Council of Chalcedon (451), the case of Dioscorus of Alexandria at the Council of Chalcedon, and the case of Anthimus of Constantinople at the Resident Synod of Constantinople (536). In the final part I proceed to an assessment of this process’ evolution over the period in question. The principal conclusion is that by the time of Justinian the ecclesiastical threefold summons procedure had become consolidated and systematised.

Abstract This paper, reflecting Fergus Millar's work on linguistic and cultural diversity in the Roman empire, surveys the evolving relationship of Latin and Greek as languages for Roman law. Normative texts remained predominantly Latin until the completion of Justinian's codification (534), even though that was a genuinely bilingual product. However, following the already existing pattern in the Greek east, a vast corpus of Greek materials was then quickly created to teach the codification in the official law schools. Designed to aid engagement with the source-texts, these ended up superseding them. Roman legal Greek, a mixture of Latin terminology plus standardized Greek vocabulary, became stabilized. After 534, new legislation was most often in Greek, necessitating parallel Latin materials to help Latin-speaking students, although sixth-century collections of Novels (‘new laws’) were still bilingual. In practice, however, in most of Justinian's empire, a lawyer (such as Dioscorus of Aphrodito) could function with limited Latin. Soon Roman law would bifurcate into two monolingual traditions, Greek in the east, Latin in the west.

Annotation:

Yam (Dioscorea. sp.) is an edible starchy tuber with potential for being a commercial source of starch for industrial purposes, but yam starch is underutilized. The dynamic oscillatory and thermal properties of yam starches from sixteen varieties each of Dioscorea. rotundata, Dioscora. alata, Dioscorea. bulbifera and one variety of Dioscorea. dumetorum from Nigeria were studied to determine their potential for industrial utilization. The storage modulus, loss modulus, damping factor and complex viscosity as a function of frequency (ω) of the dioscorea gels, as well as the onset temperature (To), peak gelatinization temperature (Tp), end of gelatinization (TC), and gelatinization enthalpy of the starches were determined by standard procedures. Results showed that all the dioscorea starches showed a typical elastic behavior with the magnitude of G′ greater than G″ while tan δ < 1 in all varieties. Thus, the starch gels were more elastic than viscous. All the starch gels exhibited shear thinning characteristics and showed frequency (ω) independence characteristics of weak gels. D. rotundata varieties had the lowest ∆Hgel, while D. bulbifera varieties had the highest. The diversity of the visco-elastic and thermal properties of the yam starch gels from different varieties and species can be an advantage in their utilization in both food and non-food industries.

Annotation:

The radical nature of the Lateran Synod of 649 – which anathematized three patriarchs from Constantinople, one from Alexandria, two imperial laws, and one bishop identified as the heresiarch – was unprecedented in the history of the church. Hence the Synod represents the high point of the Monothelete controversy. This article analyzes its acts in order to identify the kind of synod which the Lateran gathering understood itself to be, thereby demonstrating that this papal synod, the most important of the early middle ages, constituted itself as a court of justice and pretended to go through a so-called synodal accusatory legal process. Patterning their proceedings after the example of the fifth-century lawsuit against Eutyches, Nestorius and Dioscorus, the gathering claimed to be following, in a canonically faithful manner, the standing synodal legal procedure according to the church’s statues. However, the examination of the actual trial reveals serious breaches of legal procedure. The mandatory summons of the accused was omitted, thereby taking away any possibility of their defense. Moreover, the absolute separation of prosecutor and judge was undermined and, because they were written beforehand, not only the record of the process but also its judgement were a farce. Relying on a theology of Roman primacy, the synod posited a Roman competence which challenged the actual authority of an ecumenical council convened by the emperor. In this respect, here is the first early medieval attempt to replace the institution of the ecumenical council with a papally led Concilium universale. Conceptionally organized by Maximus the Confessor with Popes Theodorus I and Martin I, and staged as a literary product by him and his students, the Lateran Synod was, according to canonical and imperial law, an illegal event which rendered any agreement in the theological controversy impossible.

Annotation:

Poetaster, plagiarist, parrot, and so on. During the last two centuries, Colluthus has been widely reputed an utterly bad poet by both amateur readers and professional scholars: his reputation is not much better than that once enjoyed by, say, Eudocia or Dioscorus of Aphrodito. It is therefore unsurprising that the literary features of his poem have won very little attention from the res publica philologorum. Efforts have been made to emend its (very badly transmitted) text, and much ingenuity has been devoted to the study of its sources and its diction; but few scholars have tried to analyse the Rape of Helen as a literary work. The present paper hopes to be a first step towards such a goal. Let me say from the very beginning that I am not concerned at all with Colluthus' inspiration, skill or the quality of his poetry. This is not what I mean by speaking of a ‘revaluation’ of our poem. Nor am I trying to follow in the steps of Giangrande, who once made a sustained effort to demonstrate that Colluthus was fond of learned allusion in an almost Alexandrian way—Giangrande rightly pointed to Colluthus' irony, but his interpretations of single passages and phrases were for the most part ill-founded, and it was quite easy for Livrea, in a spirited reply to Giangrande, to dispose of them. My concern is a simple one: what was the aim of the Rape of Helen? Are there any ‘signs of life’ in those 394 hexameters—to put it in other words: are we sure that Colluthus aimed at a slavish rewriting of the story of Paris and Helen with the bare addition of some Nonnian flavour, or rather may we suppose that his poetical project was slightly more ambitious?

Abstract A soluble viscous protein was purified from yam (Dioscorea opposita Thunb.) tuber mucilage tororo by chromatographic steps, and its functional properties were estimated. The purified dioscorin having the molecular weight of about 200 kDa exhibited high scavenging activities against hydroxyl radicals (IC50 = 195.1 μg/ml) and superoxide anion radicals (IC50 = 92.7 μg/ml). Moreover, it showed extremely high angiotensin I-converting enzyme inhibitory activity (IC50 = 41.1 μg/ml). The results suggested that yam D. opposita tuber has a wide spectrum of strong antioxidative and antihypertensive activities and it could be utilized as a source of natural antioxidant.

Annotation:

In contributing to the debate on the transformation of late Roman world, some scholars have claimed that the boundaries between religious groups were fluid with external and internal factors. Christian identity was not characterised by clear indications of religious belief, observance, and practice. Some intriguing surveys have shown that the difference between Christians and pagans can be seen as part of a discursive binary. While the North African evidence of their identity allows us to consider the question of what it means to be a Christian, it is noteworthy that there is a comprehensive framework for the understanding of human behavior and thought: the ‘spiritual exercises’ in the Greco-Roman tradition. In the fourth and fifth centuries, Christian thinkers began to pursue the matter in question as being linked with the context of his concern for Christianness in late North Africa, the correlation still remains in question. In this article, therefore, first I examine how he referred to the Christian code of behavior in his letters. In particular, focusing my attention on epistolary correspondence of Augustine with two seemingly ‘pagans’, I show how he tried to impose the idea of ehe Christian norms of behavior on his correspondence –with Dioscorus (epp. 117 and 118) and with Volusianus (epp. 132, 135, and 137). Then I ask what Augustine understood by spiritual training. For the sake of clarity, I have divided the letters along he thematic line into three groups –the intellectual and therapeutic (ep. 26, 37, 56, 102, 162, 193, 202A, and 2*), the religious and eschatological (ep. 92, 130, 131, 137, and 157), and the exegetical aspect (ep. 28, 137, 149, 199, and 213). In each group I consider them chronologically as far as possible. Finally, I consider the principal feature of spiritual training, thereby coming to the enhancement of spiritual affinities, and mutual relationships of which he made use in speaking about Christian identity.

Gastric ulcer is a pathological condition characterized by damage to the mucosal and submucosal tissue layers of the stomach. The main proteins targeted in the treatment of gastric ulcers are CCKBR, CHRM3, CHRM5, and H2R because of their roles in the regulation of gastric acid secretion. Dioscorea alata (DA) is known to contain various active compounds with high sapogenin, diosgenin, and dioscorin content, in addition to its carbohydrate content. We investigated the potential of DA compounds to bind to these proteins in silico. Compound and protein structures were retrieved from PubChem (https://pubchem.ncbi.nlm.nih.gov), ChemSpider (http://www.chemspider.com), and the RCSB PDB (https://rcsb.org). Proteins and compounds are prepared first, and then docked to obtain the interactions that might form, and finally visualized to observe the interactions that have been constructed. The results showed that diosgenin and prosapogenin have potential as inhibitors of CCKBR and CHRM5, and diosgenin and dimethyl batatasin IV have potential as inhibitors of CHRM3 and H2R. We conclude that diosgenin, prosapogenin, and dimethyl batatasin IV in DA compounds have the potential to inhibit CCKBR, CHRM3, CHRM5, and H2R for gastric ulcer treatment. It is necessary to further study the effect of Dioscorea alata in vitro through a gastric ulcer model study.

The main proteins targeted in the treatment of gastric ulcers are CCKBR, CHRM3, CHRM5, and H2R because of their roles in the regulation of gastric acid secretion We performed an in-silico study to investigate the potential of DA compounds to inhibit these proteins. Compound and protein structures were retrieved from PubChem, ChemSpider, and the RCSB PDB. Proteins were prepared with Swiss PDB viewer v. 4.10. Compounds were prepared with Open Babel in Cytoscape v.3.9.1. Docking was done with AutoDock Vina in PyRx v.0.9.7. Visualization was done with Discovery Studio v. 19.1 We determined that several DA compounds have the potential to act as inhibitors of CCKBR, CHRM3, CHRM5, and H2R by reviewing the predicted binding energy, competitive properties based on literature studies and the bioactivity and molecular docking analysis. The results of this study are expected to be the basis for further gastric ulcer treatment research GRAPHICAL ABSTRACT

Annotation:

This review paper notes that the nutritional essence of an indigenous people’s diet can, broadly, be outlined in terms of their food-inherent bioactive chemical functions. Two food crops; Yam (Dioscorea spp.) and the Oil-palm (Elaeis guineensis), define Forest West Africa, agriculturally, as Yam or Palm belt. They can also be said to, broadly, define the diet of the region, which staple base they constitute, as the Yampalm Diet type. Some unique, bioactive, chemical functions of yam identified include; dioscorin, lipoic acid, potassium, biotin and, thiocyanate, while those of oil-palm include; tocotrienols, carotenoids, retinoids and lauric acid. These alkalizing food functions are, in theory, complementary to the acidic tropical physiology of Forest West Africans. Fed on other than the Yampalm diet, Forest West Africans have been demonstrated to be highly susceptible to metabolic syndrome due to adopted alien diets. Examples are lactose intolerance from milk and inflammation reaction to wheat gluten. Some food functions of Yampalm diet; dioscorin in yam and tocotrienol from oil-palm, as examples, are efficacious in metabolic syndrome management. They are potential ‘Gene-adapted food-function supplements’ for emigrants from this area who adopt alien diets. Experiments have shown that restoration of the Forest West African diet ameliorates metabolic syndrome among the people, including their Diaspora in America. Restoration of, genetically or epigenetically, adapted indigenous diet among peoples recommends itself as part of management strategy for modernization diseases.Key terms: Yampalm diet, food function, dioscorin, tocotrienol, alien diet, lactose intolerance, metabolic syndrome, epigenetic adaptation.

Annotation:

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

Annotation:

Species of the genus Dioscorea are widely distributed throughout the world. It is a resource used in different countries because theyproduce tubers that offer numerous benefits for human health due to their diosgenin content, a compound that is used as: anti-inflammatory, androgenic, estrogenic and in the preparation of contraceptive drugs; It is also mentioned that these compounds havecytotoxic, antitumor, antifungal, immunoregulatory, hypoglycemic and cardiovascular properties, they are also used for theprevention and treatment of degenerative diseases. Species such as Dioscorea bulbifera, Dioscorea cayenensis, Dioscorea colletii,Dioscorea deltoidea, Dioscorea futschauensis, Dioscorea nipponica, Dioscorea panthaica, Dioscorea parviflora, Dioscoreapolygonoides, Dioscorea pseudojaponica, Dioscorea spongiosa, Dioscorea villosa, Dioscorea composita, Dioscorea zingiberensis,produce a higher concentration of diosgenin. The tubers and roots of this group are part of the oldest foods consumed by humans,given their high nutritional, ecological and economic level. In many tropical countries, the use of various tubers and roots of thegenus Dioscorea play a very important role as a main source of energy and essential nutrients at low cost, they are also used asfodder for livestock and a source of income. This plant are rich in starch, vitamins, minerals and lipids, and have the potential tofight hunger in third world countries. Currently there is little or no knowledge in Mexico on how to cultivate these species.

Annotation:

Proximate analysis of Dioscorea hispida tubers, collected from five locations around Leuser ecosystem in Aceh Province, showed variations amongst samples. Standard AOAC method for proximate analysis of the fresh weight showed that the water content varied between 15.8 - 37.8%, crude protein 1.13 -6.20%, crude lipid 1.99 - 9.36% and ash 0.29 - 1.24%. The total carbohydrate was high, i.e. between 58.3 -71.9%. The main mineral was phosphorus, with a value of 11.7 - 46.9 mg/100g. These variations could be due to soil, climate and weather factors, as well as postharvest handling. Phytochemical tests showed that all of the samples contained alkaloids and terpenoids. One of the samples (LP) also contained phenol and steroid. The high cyanide content in the tubers (379 - 739 ppm) was easily removed by repeated washing. The cyanide level dropped significantly after the 3rd wash. Information on nutritional content in D. hispida is essential for planning its utilization. Increasing the economic value of D. hispida is expected to attract people around the Leuser ecosystem to cultivate and utilize it, thereby reducing illegal forest encroachment.Keywords: Dioscorea hispida, proximate, Leuser, janeng, gadung, starchREFERENCESBarton H 2014 Yams: Origins and Development, Encyclopaedia of Global Archaeology, p 7943-7947, (Springer.

Nine species (wild and cultivated) and some interspecific (wild × cultivated) hybrids were analysed by flow cytometry. This study confirms various polyploidy levels within cultivated species. DNA index varied by a factor of 1 to 3 for Dioscorea alata, 1 to 2.25 for Dioscorea bulbifera, and 1 to 2 for Dioscorea cayenensis-rotundata, depending on the clone or cultivar considered. In wild species, only one DNA index per species was obtained. Whenever a relationship between DNA index and chromosome number could be established, the size of genome 1C was evaluated in picograms and base pairs. Two genome sizes were observed: genome A in D. cayenensis-rotundata, Dioscorea abyssinica, Dioscorea mangenotiana, and Dioscorea praehensilis and genome B in Dioscorea togoensis. These genomes were small sizes, only 1.5 to 2.1 times larger than that of Arabidopsis. Key words: yams, Dioscorea, flow cytometry, DNA index, genome size.

Annotation:

The quest for a food secure and safe world has led to continuous effort toward improvements of global food and health systems. While the developed countries seem to have these systems stabilized, some parts of the world still face enormous challenges. Yam (Dioscorea species) is an orphan crop, widely distributed globally; and has contributed enormously to food security especially in sub-Saharan Africa because of its role in providing nutritional benefits and income. Additionally, yam has non-nutritional components called bioactive compounds, which offer numerous health benefits ranging from prevention to treatment of degenerative diseases. Pharmaceutical application of diosgenin and dioscorin, among other compounds isolated from yam, has shown more prospects recently. Despite the benefits embedded in yam, reports on the nutritional and therapeutic potentials of yam have been fragmented and the diversity within the genus has led to much confusion. An overview of the nutritional and health importance of yam will harness the crop to meet its potential towards combating hunger and malnutrition, while improving global health. This review makes a conscious attempt to provide an overview regarding the nutritional, bioactive compositions and therapeutic potentials of yam diversity. Insights on how to increase its utilization for a greater impact are elucidated.

Annotation:

Four different molecular techniques were used to assess relationships among 21 accessions of Guinea yam (Dioscorea rotundata and Dioscorea cayenensis) and 21 accessions belonging to seven putative progenitor species. Random amplified polymorphic DNA (RAPD) and microsatellite-primed PCR (MP-PCR) analysis yielded 246 informative characters that were transformed into a matrix of pairwise distances and analyzed by neighbor joining or split decomposition. Both methods gave congruent results. Well-separated groups were formed that corresponded to their species designation. Dioscorea rotundata and D. cayenensis accessions were clearly separated from each other, supporting the concept that both are distinct species. Two morphological intermediates grouped together with D. rotundata. All investigated species fell into two main clusters, one comprising D. rotundata, D. cayenensis, Dioscorea abyssinica, Dioscorea liebrechtsiana, and Dioscorea praehensilis, the other comprising Dioscorea smilacifolia, Dioscorea minutiflora, Dioscorea burkilliana, and Dioscorea togoensis. The same grouping was also obtained by comparative sequence analysis of chloroplast DNA, which supports earlier studies of nuclear rDNA variation and chloroplast restriction fragment length polymorphisms. We also analyzed the same set of Dioscorea samples with the recently developed random amplified microsatellite polymorphism (RAMPO) technique. A series of diagnostic RAMPO bands was identified that clearly distinguished between D. rotundata and D. cayenensis. Some of these bands could also be traced back to the putative progenitors of both species. The evolutionary origin of Guinea yam is discussed in light of the present results.Key words: random amplified polymorphic DNA, RAPD, random amplified microsatellite polymorphisms, RAMPO, chloroplast DNA, genetic relatedness.

The record of 2n=40 chromosome in the sexual phenotypes of Dioscorea hamiltonii, Dioscorea glabra and Dioscorea pubera are the first time report from Tripura, North East India. Moreover the somatic chromosome counts of 2n=60 in Dioscorea pentaphylla would be attributed as a new cytotype. However at the respective ploidy level no difference in somatic chromosome count was observed between their sexes.

This study was driven by the stringent environmental legislation concerning the consumption and utilization of eco-friendly materials. Within this context, this paper aimed to examine the characteristics of starch and fibres from the Dioscorea hispida tuber plant to explore their potential as renewable materials. The extraction of the Dioscorea hispida starch and Dioscorea hispida fibres was carried out and the chemical composition, physical, thermal, morphological properties, and crystallinity were studied. The chemical composition investigations revealed that the Dioscorea hispida starch (DHS) has a low moisture t (9.45%) and starch content (37.62%) compared to cassava, corn, sugar palm, and arrowroot starches. Meanwhile, the Dioscorea hispida fibres (DHF) are significantly low in hemicellulose (4.36%), cellulose (5.63%), and lignin (2.79%) compared to cassava, corn hull and sugar palm. In this investigation the chemical, physical, morphological and thermal properties of the Dioscorea hispida fibre and Dioscorea hispida starch were examined by chemical composition investigation, scanning electron microscopy (SEM), particle size distribution, thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), and Fourier transform infrared (FTIR), respectively. It was found that Dioscorea hispida waste is promising alternative biomass and sustainable material with excellent potential as a renewable filler material for food packaging applications.

AbstractDevelopment of core collection representing the diversity in the entire germplasm creates a better access and enhanced utilization of the main collection thus allowing rapid evaluation in crop improvement programs. Core collections are dynamic in nature and needs revisiting when additional germplasm and information becomes available. In the current study, an attempt was made to re-define the previously developed yam (Dioscorea spp) core collection using 56 morphological traits. Information on additional acquired germplasm and presence of duplicates or mislabelled accessions in the entire collection was also used. The re-defined core collection consisted of 843 accessions and represented about 20% of the entire collection. It included six Dioscorea species, of which accessions of Dioscorea rotundata are in the majority (73.54%) followed by Dioscorea alata (21.35%), Dioscorea bulbifera (1.66%), Dioscorea cayenensis (1.42%), Dioscorea dumetorum (1.42%) and Dioscorea esculenta (0.59%). The Shannon weaver diversity index and principal component analysis revealed the maximum diversity captured in the core from the base collection. This re-defined core collection is more valuable than the original core since it represents true-to-type accessions ensuring reliability for enhanced utilization of germplasm in yam improvement programs.

Dioscorea spp (Yam) is one of the potential local food producers. It has advantage of high species diversity, containing high carbonhydrate and easy to grow. The aim of this research is to determine the variants of Dioscorea spp, examine the structure and composition of trees around Dioscorea spp habitat and determine the enviromental factors of Dioscorea spp habitat. The research was carried out in May-June 2017. The sampling technique was using exploration and quadratic method by plotting the trees into 5 squares (10 m x 10 m) with diameter of stem more than 10 cm. The name of each species, number of individuals and stem diameter measurement of each plot were recorded. The data of diversity Dioscorea spp and environmental factors were analyzed by sort of descruptive set and the trees was analyzed by vegetation analysis. The results showed that 4 species of Dioscorea spp. There are D. hispida, D. bulbifera, D. alata and D. esculenta. D. alata has 3 variants called uwi ireng, uwi ungu and uwi bangkulit. D. esculenta has 2 variants called gembili bebek and gembili terpong. The trees around Dioscorea spp obtained 21 species with the most important index is banana (Musa paradisiaca) and sengon (Albizia chinensis). The environmental factors were indicated the appropiate growth of Dioscorea spp. Key words: Dioscorea spp, local food stuffs and variant types
