Abstract: The present study was carried out using 29 parents (25 lines x four testers) and 100 hybrids with the aim of determining the genetic variability and genetic parameters for yield and yield related traits along with 16 traits in rice. The 29 parental genotypes and their 100 F₁^,s were evaluated for yield and its associated traits during Kharif 2018. The analysis of variance revealed highly significant mean sum of squares due to treatments, parents and crosses for all the sixteen characters. PCV was higher than the genotypic GCV for all the traits. High heritability coupled with high genetic advance was observed for leaf area, spikelets per panicle, grains per panicle, L:B ratio and grain yield per plant indicated that additive genetic control in the inheritance of these traits and selection pressure could be profitably applied on these characters for yield improvement in rice.
