Abstract: In the present study, during kharif 2017 and 2018, genetic variable, the genotypic and phenotypic coefficients of variation and heritability for fifteen characters in one hundred and thirty RIL populations derived from a cross between Basmati 370 and Pusa basmati 1121of rice was studied. All the characters taken under observations among the genotypes showed that there were highly significant differences for analysis of variance. Genotypic coefficients of variation were lower than the corresponding phenotypic coefficients in all the traits studied, indicating considerable influence of the environment on the expression of the traits. High heritability was estimated for panicle length (99%), grain length (75%), length breadth ratio (74%), plant height (67%), kernel elongation ratio (63%) and kernel elongation(60%) suggesting these traits are under high genetic control. High phenotypic variation was observed for yield per plant (65.73%), grain weight (40.24%), grains per panicle (20.20%) and plant height (18.39%) while number of effective tillers per panicle (11.02%) and remaining traits revealed low genotypic coefficient of variation (<10%) except for grain per panicle (14.53%). Therefore, the results suggest that these traits can be used for grain yield selection.
