Abstract: Genetic diversity among 25 genotypes of maize were estimated by using Mahalanobis D2 statistic for eight characters. The genotypes were proposed into seven clusters. The inter-cluster distances were larger than the intra-cluster distance suggesting wider genetic diversity among the genotypes of different groups. The cluster III contained the highest number of genotypes. The cluster III also produced highest grain yield and 1000-grain weight. The highest inter cluster distanced was observed in between cluster III and II and of lowest between cluster IV and V. The highest intra-cluster distance was noticed in cluster IV and lowest for cluster VI.
