Abstract

The present investigation is carried out to study the genetic divergence among 35 finger millet genotypes for fourteen morphological characters using Mahalanobis D2 statistics during kharif, 2014. D2 statistics indicated that the genotypes studied were genetically diverse. The 35 genotypes of finger millet were grouped into 6 clusters irrespective of geographical diversity, indicating no parallelism between geographic and genetic diversity. Clusters I and VI were highest number of 8 genotypes, followed by cluster II and V with 7 genotypes and cluster III with 4 genotypes. Cluster IV was monogenotypic. The highest inter-cluster distances was observed between cluster IV and V followed by cluster IV and VI, cluster II and IV, cluster I and IV, cluster III and V and cluster III and IV suggesting the use of genotypes from these clusters to serve as potential parents for hybridization. Considering cluster mean and genetic distance the crossing of entry of clusters IV with entries of cluster V and those genotypes of cluster VI would be fruitful for obtaining transgrassive segregants for developing high yielding and better quality finger millet varieties.
