ABSTRACT
Genetic diversity for yield and yield attributing characters was studied in maize using thirty nine inbreds
of maize. The thirty nine inbreds of maize were categorized into twelve clusters. Based on genetic
divergence intra cluster values ranged from 0.00 (mono genotypic clusters III, IV, V, VI, VII, VIII, IX, XI
and XII) to 9.25 (cluster X). The minimum inter cluster distance was observed between cluster VI and
cluster VIII (8.21) followed by between Cluster III and cluster V (8.28). The maximum inter cluster
distance was observed between cluster III and cluster XI (16.89) followed by between cluster III and
cluster XII (16.54). The contribution of each character towards total genetic diversity, in that out of 12
characters, grain yield per plant (31.71%), days to 50% tasseling (22.81%) and 100 grain weight
(18.62%) contributed high for divergence.
Keywords - Genetic diversity, Zea mays, Genotypes, Hybrids.
