Agro-morphological characterization of beans of the phaseolus genus and identification of their cultivated species in Benin (West Africa)

The local cultivars of the Phaseolus genus present within communities constitute a considerable source genes and consequently genetic diversity which would lead to success varietal creation beans. ¶Nevertheless, these resources suffer from significant erosion because climatic requirement but also difficulties related their cultivation methods. ¶The objective this study is identify phenotypical distinctive features species cultivated in Benin for permanent management. ¶To achieve goal, an agro-morphological characterization was carried out on two years (2019-2020) March August each, at Ahossougbéta (Abomey-Calavi) following completely randomized blocks design with three replications. Data were collected on¶ twenty-three measured characters 88 accessions. subjected descriptive analysis, analysis variance multivariate analyses. Results showed great variability among accessions studied cultivars.¶ Three major groups identified characterized by AFD.¶ more shape first leaves, color flowers, integuments, width pods, times flowering appearance pods length pods. These results are significantly important classification beans genus. In addition, morphological molecular characterizations necessary each specie order define strategies improvement conservation Benin.
