Estimation of heterosis and inbreeding depression for yield, its components and qualitative traits in rice (Oryza sativa L.)
Patel HR and Patel PB
The present investigation was carried out at Main Rice Research Centre, Navsari Agricultural University, Navsari during kharif 2018-19. The experimental material for the present investigation comprising of five generation viz., P1, P2, F1, F2 and F3 of following three crosses of rice (Oryza sativa L.) were used to study heterosis and inbreeding depression of yield, its components and qualitative traits. Heterosis of hybrids over mid parent and better parent varied from cross to cross and character to character. For grain yield per plant only cross-I (IET-25475 x IET-25477) exhibited significant and positive relative heterosis as well as heterobeltosis and cross-I also exhibited positive and significant relative heterosis for three important yield attributing traits viz., productive tillers per plant, grains per panicle and 100 grain weight.
