ABSTRACT
An investigation was carried out to assess the genetic divergence of the newly developed inbred lines of maize in compassing of thirty inbred lines and three testers were evaluated in RCBD during Kharif 2012. Observations documented on fourteen quantitative and unique morpho-physiological traits and analysis of variance reveal highly significant difference among all inbred lines. In addition inbred lines were further grouped into six clusters, indicating the presence of genetic diversity among the inbreds. The cluster I is having highest number of genotypes (17) and the maximum inter cluster distance was observed between clusters II and III (17.08). Highest intra cluster distance was being observed in cluster I (8.09) and wide range of variation was observed in cluster mean performance for the characters studied. These genetically diverse inbred lines can be further used for developing superior hybrids for improved productivity.
Key words: Genetic diversity, Morph-physiological traits Variance, Inbred lines, Cluster and Hybrids.
