Abstract

The experiment was carried out at the College of Agriculture, Raichur, during rabi 2020. It was undertaken to assess the nature of genetic variability and diversity among 120 colored sorghum genotypes. The study revealed wide variation for yield and yield attributing traits, high GCV and PCV coupled with high heritability and genetic advance was observed for neck of panicle, peduncle length, 100-grain weight. The traits viz., plant height, neck of panicle, peduncle length, panicle length, 100-grain weight, panicle weight and grain yield per plant showed high heritability and genetic advance as percent of mean. Wide genetic diversity was observed among the genotypes as evidenced by the formation of seven clusters for the 120 colored genotypes based on different traits studied. Out of ten characters studied, contribution of plant height towards genetic divergence was the highest followed by panicle weight.
