Genetic Variation, Heritability and Genetic Advance in Some Promising Rice Hybrids

Eleven rice hybrids including two check varieties were evaluated to approximate their genetic variability, heritability and advance for ten quantitative traits. The analysis of variance illustrated that all the traits differed significantly indicating enough variation is presenting studied materials. Among desirable number filled spikelet’s per panicle was found have highest both phenotypic genotypic followed by total panicle. Almost characters showed a little between PCV GCV revealing influence environment on expression High coupled with high observed panicle, plant height unfilled Such findings stipulated these governed additive gene actions which are fixable may be accounted reliable index selection. genotypes G3 (IR79156A × EL108R) G6 EL253R) selected as response superior promising achievable yield advantage 49% 23%, respectively over best varieties. Therefore, proposed extensively further trial variety release.
