Abstract
Twenty (20) aromatic traditional rice varieties of Chhattisgarh with three checks (CG Devbhog, Dubraj Selection 1 and Pusa RH 10.) were evaluated for variability among yield and yield contributing traits in rice at Raipur (C.G.). Analyses of variance indicated that the mean sum of squares due to genotypes was found to be significant for all the traits. The highest GCV was recorded for sterile spikelets/panicle (38.70) followed by pollen fertility (%) (36.82), grain yield (g) (36.45) and biological yield (25.53). The highest PCV was recorded for sterile spikelets/panicle (38.88) followed by pollen fertility (%) (36.83), grain yield (g) (36.49) and biological yield (25.58). The magnitude of PCV was higher than the corresponding GCV for all the traits. The significant genetic variability in any breeding material is a prerequisite as it does not only provide a basis for selection but also provide some valuable information regarding selection of diverse parents for use in hybridization programme.
