Abstract:
The present investigation was undertaken to study heritability and genetic advance (GA) for grain yield and quality traits in aromatic rice (Oryza sativa L.). Four rice hybrids were evaluated to their genetic heritability and genetic advance for quality traits. The analysis of variance illustrated that all the traits differed significantly indicating that enough variation is presenting the studied materials. High heritability coupled with high genetic advance were observed in cross-III (IET-26214 × GAR-1) for grain yield per plant and kernel breadth for cross-II (IET-24617 × NWGR-9081) and cross-IV (IET-26215 × GNR-2); straw yield per plant for all crosses except cross-III (IET-26214 × GAR-1); protein content for cross-IV (IET-26215 × GNR-2); milling for cross-II (IET-24617 × NWGR-9081) and cross-III (IET-26214 × GAR-1) and hulling (%) for cross-I (GR-104 × IET-26215),which indicated that heritability of these traits were under the control of additive gene action and a good scope of selection using their phenotypic performance. Considering, all of these yield and yield related characters could be used for selection in rice breeding programs.
