Abstract
The genetic diversity of agro-morphogenic traits in 14 genotypes of soybean (Glycine max L. Merr.) were studied in an experiment using a Complete randomizes Design (CRD). Each trait's analysis of variance revealed a substantial difference between genotypes. Multivariate analysis based on thirteen characters of fourteen soybean genotypes was divided into four clusters. The maximum contribution of traits towards diversity was observed by days to 50% flowering, plant height, number of main branches per plant and leaf area index. As a result, these traits could be emphasized during selection of parents for hybridization. The highest inter cluster distance was observed between cluster II and IV and the maximum intra cluster distance was found in cluster III. Considering group distance and other agro-morphogenic performance, genotypes G1 (BADC SV1) from cluster II, G10 (Asset-95) and G7 (BS-29) from cluster VII, G4 (GMOT-43) and G12 (BADC SV2) from cluster IV found potential for future hybridization program.
