 ABSTRACT

A trial was conducted to study selection parameters for grain yield and related characters in a diallel cross set of 10  parents, 45 F1 s and 45 F2  s  barley were evaluated in randomized complete block design with three replications. The genetic parameters estimated for the traits based on   mean performance, narrow sense heritability and genetic advance. The high heritability coupled with high genetic advance was observed for one character biological yield per plant in F1 generations. Moderate heritability with moderate genetic advance was found for 1000-grain weight in both generation and leaf area index, grain yield per plant in F2 generation, indicating that selection in later generations would be much rewarding. Low heritability with low genetic advance was found for days to 50% flowering and days to maturity in F2 generation.

Key words: Generation, Grand mean Heritability (narrow sense) and genetic advance in per cent of mean.
