Elucidation of Genetic Parameters Controlling Yield and Quality Traits in Rice (Oryza sativa L.)

Background: Forty two crosses involving seven lines and six testers were studied for economically important yield contributing quality traits to test the magnitude of genetic components diversity. Formulation efficient breeding methodology is possible by targeting architecture genotypes. Methods: The systematic programme involves generating variability besides sorting off diverse genotypes utilizing extreme phenotypes producing stable varieties. Genetic diversity helps achieve greater continuum in segregating populations reach ideal selection progenies. Heritability advance are other parameters retrieving better genotype through selection. Result: Significant differences analysis variance recorded all traits. results signified value phenotypic coefficient variation (PCV) than genotypic (GCV) environment (ECV) pertaining studied. Among agronomical characters, GCV PCV reported be higher estimate number productive tillers per plant, grains panicle, single plant among characters gelatinization temperature (GT), length breadth (LB) ratio, gel consistency amylose content. present study adverted that grain viz., tillers, yield, height, 1000 weight, milling percentage could easily inherited next generation due high heritability. Whereas elongation ratio linear influenced environmental factors their low Further, Gel content exhibited PCV, GCV, heritability hence direct can made target
