Abstract:
Twenty-nine rice genotypes along with three checks were evaluated with an objective to determine the nature and magnitude of genetic variability for yield and grain quality characters. A study of the analysis of variance showed the presence of a high degree of genetic variability among the genotypes. Phenotypic coefficient of variance and Genotypic coefficient of variance were high for number of filled grains/panicle (23.99, 23.32) and moderate for flag leaf area (19.40, 18.21), grain yield (18.75, 17.82), 100-grain weight (13.47, 13.40), plant height (11.68, 11.21) and number of effective tillers/plant (13.98, 9.73). High heritability along with high genetic advance percentage over mean was observed for no. of filled grains per panicle, flag-leaf area, grain-yield, and 100-grain weight. Most of the genotypes had long-slender grain type with kernel-length ≥6 mm, L/B Ratio ≥3.0, and showed an intermediate range of amylose content, gelatinization temperature, and medium to soft gel consistency.
