Direct and Indirect Effects of Yield Contributing Traits in Rice (Oryza sativa L.)

At the Field Experimentation Centre of Department Genetics and Plant Breeding, 20 rice genotypes, including one check variety, were assessed in order to research genetic variability, heritability, progress, correlation, path coefficient for 13 quantitative features. In Kharif 2022, experiment was carried out utilising a Randomised Block Design with three replications. Over NDR 359 (check), BRRI DHAN-75 (26.133) A.K.DHAN (23.067) demonstrated greater yield. Number spikelets per hill, panicles Biological yield, tillers Grain yield Harvest index, Panicle length, Test weight, Days maturity, height all had high moderate estimations GCV, PCV, Genetic Advance as Percent Mean. Estimates heritability ranging from moderate, progress quantity panicle, biological yield,plant height, days 50% blooming. both phenotypic genotypic levels, grain showed strong positive connection number harvest index. index significant direct influences on hill. Thus, current experimental materials, these qualities are recognised effective prospective indirect selection increase
