Abstract:
The experiment was carried out during summer and kharif 2018-19 at Main Rice Research Centre, Navsari Agricultural University, Navsari. Six diversified elite lines of rice (IET-24772, IET-24783, GNR-2, GNR-3, GR-11 and GR-15) were used to study heritability and expected genetic advance under selection. High heritability coupled with high genetic advance were estimated for productive tillers per plant in all the three crosses; 100 grain weight in cross-II (GNR-2 x GNR-3) and straw yield per plant in cross-III (GR-11 x GR-15) which indicated that heritability of these traits were under the control of additive gene action. For improvement of such traits, selection will be rewarding.
