ABSTRACT
The present investigation was undertaken to study heritability and genetic advance (GA) for grain yield and it's contributing traits in aromatic rice (Oryza sativa L.) Four rice hybrids were evaluated to their genetic heritability and genetic advance forquantitative traits. The analysis of variance illustrated that all the quantitative traits differed significantly indicating that enough variation is presenting the studied materials. High heritability coupled with high genetic advance were observed in cross-I (GR-104 × IET-26215) for harvest index, cross-III (IET-26214 × GAR-1) for grain yield per plant and 100 seed weight and in cross-IV (IET-26215 × GNR-2) for panicle length 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..
