Abstract:

The experiment was conducted in randomized complete block design with two replications during Kharif 2016 at Rice Research Centre, Agricultural Research Institute, Rajendranagar, Hyderabad. A total of thirty three genetically diverse genotypes were considered for the study. Analysis of variance was found to be significant for all the traits, indicate that there is existence of genetic variability for all the traits varying from lower to higher coefficients of variance. The results found that the moderate genotypic and phenotypic coefficients of variance were recorded for number of productive tillers per plant, number of grains per panicle and seed yield per plant. High heritability with high genetic advance was observed for number of productive tillers per plant, 1000 grain weight, number of grains per panicle and seed yield per plant. The traits were found to have higher values of variance and selection for such traits will be practiced based on phenotypic observation.
