ABSTRACT
The present investigation was undertaken to study the genetic variability for different grain yield and malting traits as well as their interrelationship to facilitate the malt barley breeding in the country. Genetic analysis of grain yield and malting traits were conducted on 20 genotypes grown in a randomized block design with three replications at CCS Haryana Agricultural University, Hisar during rabi 2010-11. Considerable amount of variation was found in material under study. Wide range, high coefficients of variation, heritability and genetic advance as percent of mean were recorded for grain yield, husk content, grain plumpness and ?-glucan content revealed the possibilities of their further improvement. In pooled analysis, grain yield/plant found positive but non significant correlation with malt yield, hot water extract. However in independent analysis of two-rowed barley, grain yield/plant found positively and significantly correlated with hot water extract. Also, in six-rowed type grain yield/plant was positively and significantly correlated with malt yield and hot water extract. Path analysis showed that malt yield had the highest direct effect on grain yield/plant. It showed that both grain yield and malt yield can be improved simultaneously in a breeding programme.
