The Voandzou [Vigna subterranea (L.) Verdc], is generally cultivated in sub-Saharan Africa, where its production ranks third in seed legumes. The valorization of this crop is therefore one of the best alternatives to ensure the food security of the population in the face of declining production of food crops such as millet and sorghum in a country like Niger. Indeed, the control of the diversity of the voandzou will undoubtedly allow it to be taken into account in the varietal selection programs. The objective of this study is the agro-morphological characterization of thirty (30) accessions from the Nigerian Voandzou collection in the Sudanese agro-climatic zone. The data used are collected through an agronomic test set up on a Fisher device in complete random blocks, with three (3) repetitions. Sixteen (16) characters, including four phenological, six (6) morphological, and six (6) traits related to yield components were evaluated for characterization of accessions. The descriptive statistics analysis showed that the coefficients of variation ranged from 4.16% (maturity date) to 72.51% (shell weight). Significantly high values (CV> 20%) were observed for 12 characters out of 16 analyzed. Characterization revealed very highly significant differences between 11 parameters of the accessions studied. It was found that accessions Di-017, Ma-045, Ta-095 and Ta-096 are early (86 JAS) and give more pods per plant. The Zi-007 accession is the most efficient in performance components. Strong correlations were observed between the dates of the first flowering and that of fifty percent r = 0.840. Correlations of the same order were obtained between the diameter of the plants and the height r = 0.714 and between the weight of the pods and seeds r = 0.954. In order to specify the different groups Principal Component Analysis (PCA) and Ascending Hierarchical Classification (AMP) were performed. The group G3 consists of 7 accessions, are late, more productive in biomass, give better yields, but fewer pods per plant. The G2 group consists of a single accession Zi-007, which is early, more productive in biomass, yield and gives more pods per plant. Then the group G1 consists of 22 accessions that are intermediate to those of the other two groups.

Abstract: (french)
Le Voandzou [Vigna subterranea (L.) Verdc], est généralement cultivé en Afrique sub-saharienne, où sa production occupe le troisième rang des légumineuses à graines. La valorisation de cette culture représente une alternative pour assurer la sécurité alimentaire des populations face à la baisse de la production des cultures vivrières comme le mil, sorgho dans un pays comme le Niger. L’objectif de cette étude est la valorisation de la culture de voandzou pour une amélioration de sa production au Niger. Les données utilisées sont collectées à travers un essai agronomique mis en place sur un dispositif de Fisher (en blocs aléatoires complets), avec trois (3) répétitions. Seize (16) caractères, dont 4 phénologiques, six (6) morphologiques et six (6) liés au rendement ont été évalués pour la caractérisation des accessions. L’analyse de la statistique descriptive a montré que les coefficients de variation varient de 4,16% (date de maturité) à 72,51% (poids coque). Des valeurs significativement élevées (CV>20%) ont été observées pour 12 caractères sur les 16 analysés. La caractérisation a révélé des différences très hautement significatives avec 11 paramètres des accessions étudiés. Il est ressorti que les accessions Di-017, Ma-045, Ta-095 et Ta-096 sont précoces (86 JAS) et donnent plus des gousses par plante. L’accession Zi-007 est la plus performante en composants du rendement. Des corrélations fortes ont été observées entre la dates de la première floraison et celle de cinquante pour cent (r = 0,840). Des corrélations du même ordre ont été obtenues entre le diamètre des plantes et la hauteur (r = 0,714) et entre poids des gousses et des graines (r = 0,954). L’analyse en composante principale (ACP) et la classification ascendante hiérarchique (CAH) ont montré une importante variabilité entre les accessions avec la formation de 3 groupes distinctes. Le groupe G1 constitué de 22 accessions qui sont intermédiaires à celles des deux autres groupes, Le groupe G2 constitué d’une seule accession Zi-007, qui est précoce, plus productif en biomasse, en rendement et donne plus des gousses par plante. Et enfin le groupe G3 constitué des 7 accessions qui sont tardives, plus productifs en biomasse et donnent des meilleurs rendements en poids gousse, mais moins des gousses par plante.
