Abstract:

Genetic diversity is the first and important parameter in crop improvement programme. In the present investigation fifty okra genotypes were assessed to know the nature and magnitude of genetic divergence by using Mahalanobis D2 statistics. The genotypes were grouped into seven clusters. Among seven clusters, Cluster VII was largest with 11 genotypes followed by, cluster IV having 10 genotypes. The intra-cluster was maximum in cluster IV (D2 = 2.54) reveals maximum genetic diversity followed by, cluster VI (D2 = 2.38) and cluster VII (D2= 2.36). The maximum inter cluster distance was observed between cluster II and cluster V(D2 = 5.31) followed by, cluster II and VI (D2= 4.62) and minimum cluster distance was observed between VI and VII (2.32). The length of first fruiting node, length of internode, fruit shape and number of fruits per plant is the qualitative traits in okra and it is considered that the genotypes showed highest mean value among the clusters should be given more weightage. The different clusters have higher mean values for different traits and the genotypes consisting in cluster II. V and VII have higher mean value for these traits deserve to be considered as potent parents for further improvement programme.
