Genetic divergence in Leucaena varieties using non-hierarchical euclidean analysis

Nature and magnitude of genetic divergence was assessed in 49 varieties of Leucaena using non-hierarchical cluster analysis for morphological and biomass traits. The population was grouped into 9 clusters. Maximum number of genotypes figured in clusters I and IX, four in 11, and VI and one each in IV and VIII. Intra-cluster distance was found maximum for the cluster VI(2.01). Inter-cluster diversity was found maximum between clusters VI and V(11.69) and minimum between cluster III and IX (1.87). The geographical diversity was not related to genetic diversity. Clusters with small statistical distance were considered less diverse than those with large distances.
