Abstract:
Genetic divergence analysis in 65 genotypes of Indian mustard [Brassica juncea (L.) Czern & Coss.] by applying Mahalanobis’s D2 statistics indicated the presence of wider genetic diversity among the materials for 8 characters. The genotypes were grouped into nine clusters by Tocher’s method. Cluster IV was the largest group comparing with 15 genotypes, whereas cluster III and V was the second largest group consisting 10 genotypes followed in order by cluster VI and VII (8 genotypes), cluster II and VIII (5 genotypes), cluster IX (4 genotypes) and cluster I (2 genotypes). The highest intra-cluster distance was observed for cluster III (0.22). The highest inter-cluster distance was observed between cluster VI and IV (2.22). The maximum contribution to divergence was from seedling dry weight (44.71%) followed by speed of germination (30.1%), germination (8.85%), shoot length (5.67%), vigour index-I (3.66%), vigour index-ii (3.08), root length (2.02%) and seedling length (1.92). these findings could be utilized in breeding high quality seed parameters in Indian mustard.
