Abstract: The present investigation was carried out during kharif 2017-2018, at Main Rice Research Centre farm, Navsari Agricultural University, Navsari. The experimental material for present investigation comprised of Six generations viz., P1, P2, F1, F2, BC1 and BC2 of following four crosses were involved eight diversified cultivars of rice (Oryza sativa L.) were used to study the genetic analysis of quantitative and qualitative traits. The F1s deviated positively from their better parent for days to 50% flowering, days to maturity, plant height, productive tillers per plant, grains per panicle, 100 seed weight, grain yield per plant, straw yield per plant, harvest index, kernel L:B ratio, protein content, amylose content, Fe content, Zn content, leaf area, photosynthetic rate, chlorophyll content, hulling (%), milling (%) and head rice recovery (%) in majority of crosses, indicating importance of heterosis. Hybrid matures late in cross 1 (NAUR-1 X IET-25457) and cross 2 (GNR-3 X IET-25446) than their respective early parent as evidence from the higher value of heterosis.
