This study consisted of 33 genotypes including two checks i.e. HPR 1156 and HPR 2656 evaluated in a Randomized Block Design with three replications for various yield traits. Analysis of variance revealed significant differences among the genotypes for all the traits studied and presence of considerable amount of genetic variability for all the traits studied. High heritability coupled with moderate genetic advance and moderate phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was observed for panicle length, grains/panicle, yield/plant, yield/ plot indicated the presence of additive gene action and sufficient variability scope for improvement through selection. On the basis of mean performance for different traits studied viz., HPR 2846, HPR 2875, HPR 2839, HPR 2866, HPR 2867 and HPR 2885 were the best genotypes for yield and other yield contributing traits which may be used for the further rice breeding programme.
