Abstract

Altogether, 30 germplasm of Yam bean including two released varieties viz., Rajendra Misrikand-1(RM-1) and Rajendra Misrikand-2 (RM-2) were analyzed for genetic divergence among twelve studied characters. Analysis of variance revealed highly significant differences among the genotypes for all the twelve characters under study. The (PCV) was greater than genotypic coefficient of variance (GCV) for all the characters and high magnitude of PCV and GCV were observed for traits like tuber weight followed by tuber yield indicating that these traits could be used for tuber yield improvement but wide difference between GCV and PCV were recorded for most of the traits except for the tuber yield and tuber weight. All the thirty genotypes were grouped into 6 clusters using D2 statistics. Highest inter cluster distance was observed between cluster I and III (107.53) followed by cluster III and VI (97.61) and cluster I and II (78.54) on the basis of their genetic distances. Tuber yield followed by tuber weight and seed yield were having maximum contribution towards total divergence
