ABSTRACT

Fifty three genotypes collected from IRRI, Philipines and one variety from research station were grown in randomized block design with three replications under three environments during rabi (dry) season 2013-14. Significant mean squares for genotypes indicated the presence of variability for all the characters under study. The phenotypic coefficient of variation (PCV) was higher than the genetic coefficient of variation (GCV) for all the characters studied. Small differences between GCV and PCV were recorded for most of the characters studied which indicated less influence of environment. The high heritability coupled with high genetic advance as percent of mean was observed for the characters viz., grains per panicle, straw yield per plant, grain yield per plant and 1000 grain weight indicate that most likely the heritability is due to additive gene effects and selection may be effective.
