Abstract

Genetic variability, character association and path analysis between yield and its component traits were carried out in 55 genotypes of six-rowed barley (Hordeum vulgare L.). Highly significant differences between genotypes were recorded for all the characters studied. High phenotypic and genotypic coefficient of variation coupled with high heritability and high genetic advance in grain yield/plant and moderate for grains/spike, spikelets/spike, tillers/plant, flag leaf area and plant height. Correlation and path coefficient analysis revealed that harvest index, tillers/plant, grains/spike and 1000-grain weight, were the most important characters for realizing improvement in grain yield in six-rowed barley.
