Genetic variability, correlation and path coefficient studies in F2 generation of short slender aromatic and medium slender non-aromatic rice (Oryza sativa L.)
Genetic variability, correlation, direct and indirect effects between yield and yield component traits were studied in the F2 population of MDU 6 × VGD 1 and Improved Samba Mashuri × VGD 1 for six characters. Number of filled grains per panicle and single plant yield recorded high PCV, GCV and high heritability coupled with high genetic advance as per cent mean in both the crosses which indicated the presence of additive gene action and selection may be effective for these traits. Number of productive tillers per plant had moderate PCV, GCV, heritability and genetic advance as per cent mean in both crosses. Number of productive tillers per plant also had significant positive correlation with maximum direct effect on single plant yield in both the crosses. This indicated that the selection for high number of productive tillers per plant will bring concurrent improvement in yield as well.
