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. High heritability coupled with high genetic advance was estimated in all the crosses for grain yield per plant except cross 4 (IET-15429 X IET-25453); plant height for cross 2 (GNR-3 X IET-25446); straw yield per plant for all crosses except cross 4 (IET-15429 X IET-25453); protein content for cross 3 and cross 4 (IET-15429 X IET-25453); Zn content for cross 1 (NAUR-1 X IET-25457) and cross 3 (GNR-5 X IET-25471) and head rice recovery (%) in cross 4 (IET-15429 X IET-25453), suggesting that these characters can be further improved by adopting selections in succeeding generations.
