In order to access the genetic diversity, twenty five diverse strains of barley were subjected to D2 statistics for nine quantitative traits viz. days to flowering, plant height, number of productive tillers per plant, ear length, number of grains per ear, grain weight per ear, 1000 grain weight, seed hardness and grain yield per plant. Genotypes were grouped into five clusters. Cluster I and II were most divergent. The genotypes of these three clusters may be used for hybridization programme. 1000 grain weight and plant height contributed more towards total divergence.

Abstract


In order to access the genetic diversity, twenty five diverse strains of barley were subjected to D2 statistics for nine quantitative traits viz. days to flowering, plant height, number of productive tillers per plant, ear length, number of grains per ear, grain weight per ear, 1000 grain weight, seed hardness and grain yield per plant. Genotypes were grouped into five clusters. Cluster I and II were most divergent. The genotypes of these three clusters may be used for hybridization programme. 1000 grain weight and plant height contributed more towards total divergence.
