Abstract

Description of the subject: The genetic diversity of a vetch collection collected in Algeria was assessed by the variation of 78 plant morphological characters and 5ecogeographic parameters of the collection stations. 37 accessions belonging to 7 taxa of the genus Vicia L. were the subject of this study Objective: Characterize the accessions using two different markers and then correlate their results. In parallel, the results are used in the taxonomy and phylogeny of the populations studied Methods: the hierarchical classification in clusters using a Euclidean distance matrix based on a UPGMA – principal component analysis – the Mantel test used to correlate the matrices of ecogeography and morphology Results: Cluster analysis showed clear separation among accessions from their plant morphology but significant differences at subspecies level were observed regarding the results of investigated morphological traits. Important diversity in leaflet consistence, calyx hairness, stem form, leaflet abaxial hair density, leaflet hair elevation, seed colour, spongy inside legume and peduncle length was found in most accessions of the collection. The dendrogram obtained with ecogeographic parameters did not indicate clear division among accessions. A distribution map of each taxa was produced and data obtained can be used as a guide for future collecting missions. Conclusion: inter and intraspecific differences were obtained by the morphological descriptors. The collected eco-geographic data can be used as a guide for future collection missions. Other markers should be used for the phylogeny of the collection.
