Abstract:
The experiment was consisted of nineteen rice germplasm viz; IET26383, DRR Dhan-49, R-RHZ-1B-80, R-RH-2-M1-93, CGZR-1/IET 23824, Samba mahsuri, DRR Dhan 48, CR Dhan 311, R-RHZ-SM-14, MI 127, R-RHZ-1H-82, IR 64, CGZR-2(IET23824), Zinco rice(IET25477), CR Dhan-310(IET 24780), R-RHP-MI-30(IET 25461), MI156, CR2818-1-11-1-B-1-1-2-B-1 and DRR Dhan 45. The analyses of variance revealed that mean sum of squares were highly significant for all the traits for rice genotypes. Genetic variability, phenotypic coefficient of variability (PCV), genotypic coefficient of variability (GCV), heritability in broad sense and genetic advance in percent of mean were analyzed. High variability was observed in case of plant height cm, grain width and total spikelets. High estimates of heritability were observed for biological yield/plant. The magnitude of phenotypic correlation was higher than the genotypic correlation. Grain yield/plant showed highly significant and positive correlation with panicle length and grain width.
