Abstract:
The present study comprised of of five generation viz., P₁, P₂, F₁, F₂ and F₃ of following three crosses of rice (Oryza sativa L.) were used to study heritability and genetic advance of yield, its components and qualitative traits. The present investigation was carried out at Main Rice Research Centre, Navsari Agricultural University, Navsari during kharif 2018-19. High heritability coupled with high genetic advance was estimated for productive tillers per plant in all the crosses; 100 grain weight in cross-I and cross-II; grain yield per plant in cross-II; straw yield per plant in cross-II and cross-III; L:B ratio in cross-I and amylose content in cross-III which indicated that heritability of these traits were under the control of additive gene action. For improvement of such traits, selection will be rewarding.
