A wide genetic variability among the genotypes was revealed by the D2 analysis, where in 49 genotypes were grouped into ten clusters. Based on average inter-cluster distance, the clusters VII and VIII were found to be highly divergent from all the clusters, the intercluster D2 value was 500.33, where lowest D2 value was noticed between the clusters IV and VIII (23.35). The genotypes LRB- 461, LRB-462, LRB-463, LRB-464, LRB-465, LRB-466, LRB-467, LL-476, LRB-491, LRB-498 and LRB-490 were found to be divergent.

Abstract


A wide genetic variability among the genotypes was revealed by the D2 analysis, where in 49 genotypes were grouped into ten clusters. Based on average inter-cluster distance, the clusters VII and VIII were found to be highly divergent from all the clusters, the intercluster D2 value was 500.33, where lowest D2 value was noticed between the clusters IV and VIII (23.35). The genotypes LRB- 461, LRB-462, LRB-463, LRB-464, LRB-465, LRB-466, LRB-467, LL-476, LRB-491, LRB-498 and LRB-490 were found to be divergent.
