Abstract:
A field experiment was conducted during Kharif-2017 and Kharif-2018 involving seven diversified aromatic and non-aromatic elite lines of rice, four F₁ hybrids and their corresponding F₂ populations to study the inbreeding depression and heterosis for grain yield, yield contributing traits and quality traits. Out of four hybrids studied all the four hybrids exhibited positive and significant heterosis and heterobeltiosis for grain yield per plant. The highest heterosis and heterobeltiosis were exhibited by cross IET-26215 x GNR-2. Out of four hybrids, three hybrids viz., GR-104 x IET-26215, IET-24617 x NWGR-9081 and IET-26214 x GAR-1 showed positive and significant heterosis for productive tillers per plant and 100 seed weight.
