Abstract:

Thirty genotypes of maize were evaluated for genetic diversity using Mahalanobis D2 statistics for various morpho physiological traits during kharif, 2013. The data on 21 quantitative traits were recorded and on the basis of Mahalanobis’ D2 statistics, all the 30 genotypes of the present study were grouped into six clusters. Maximum number of genotypes (11) were included in cluster III followed by cluster-II (9), cluster-I (7) and remaining clusters were solitary with single genotype. Considering the inter cluster distances, it was highest between cluster IV and V (361.39) followed by IV and VI (357.02). Among the 21 characters studied, grain yield plant-1, stover yield plant-1, kernels per row, ear height contributed maximum towards the total divergence and were found to be responsible for primary differentiation.


Keywords: Maize, Genetic divergence, D2-statistics.
