Studies on PCV, GCV, Heritability, and Genetic Advance in Rice Genotypes for Yield and Yield Components

چکیده

The present experiment was carried out in twelve genotypes including IRRI introgression lines and a Japonica cultivar to analyse the genetic variability, heritability, gain. Significant differences were observed among genotypes. All traits under study recorded high phenotypic coefficient of variation (PCV) than genotypic (GCV) indicating presence environment controlling traits. But, less difference between PCV GCV implies that involvement had negligible role trait expression. High for characters plant height, number productive tillers, 1000 grain weight, L/B ratio, protein content, phenol reducing sugar, representing these are contributed by additive gene action direct selection will improve easily. Among studied, heritability advance obtained days 50% flowering, panicle length, grains per panicle, breadth, ascorbic acid, predominant action.
