Genetic variability in barley (Hordeum vulgare L.)

Abstract

Twenty two barley genotypes were evaluated for green fodder yield, grain yield and related morphological characters. Genotypes significantly differed for all the 14 characters indicating sufficient variability in the experimental material. The characters plant height, spike length, peduncle length, number of tillers per meter row length, test weight, green fodder yield and grain yield showed high GCV and PCV. High estimates of heritability along with high genetic advance (% of mean) were observed for plant height, spike length, peduncle length, number of tillers per meter row length, test weight, green fodder yield and grain yield. Therefore, selection will be effective for these characters.
