Abstract:

The present study was carried out to estimate genetic variability, heritability and genetic advance for 14 yield and yield related traits and 6 grain quality traits in 150 genotypes. The results showed that ANOVA for all the 20 traits under study revealed highly significant differences this indicates that a wide range of variability was present among 150 genotypes. Genetic variability analysis has shown that the variability for the traits namely filled grains, unfilled grains, single plant yield, per day productivity, gel consistency and alkali spreading value was high, for plant height, harvest index and amylose content variability was moderate and low variability was observed for days to 50 % flowering, days to maturity, panicle length and kernel length for the material under study. High correspondence between phenotypic and genotypic variance was observed for plant height, panicle length, thousand grain weight, amylose content, gel consistency, alkali spreading value and kernel length. The high environmental influence was observed for days to 50 % flowering, days to maturity, spikelet fertility, productive tillers and total number of tillers.
