Abstract:
A total of 40 lines, along with a check, were evaluated in Randomized Complete Block Design (RCBD). All the traits except number of number of primary branches per plant showed significant variation among the lines. Based on D² values, 41 genotypes were grouped into four clusters. The cluster II consists of maximum 21 genotypes followed by cluster IV, cluster III and cluster I, which had 10, 6 and 4 genotypes, respectively. Whereas, days to maturity (25.50) followed by days to 50% pod setting (19.58), days to 50% flowering (14.23) and harvest index (10.59) contributed maximum diversity. Based on cluster Euclidean distance matrix genotypes C-205 and CSJ-1100 had recorded maximum diversity (10.152). The PF Score creates a perfect base for the estimation of variability and for proper selection among complex characters. PCA-1 and PCA-2 join together come up with (51.61%) of variation among seed yield characters. Based on cluster means, cluster distances and per se performance C-205, CSJ-1100, ICC-21168, C-1028 and C-223 were identified for inclusion in hybridization programme in this region.
