The present investigation was carried out at rice research farm ofBihar Agricultural University, Sabour (Bhagalpur), Bihar in kharif, 2019 to assess the extent of genetic variability for yield and yield related traits and to estimate heritability and genetic advance in rice genotypes for drought tolerance. The analysis of variance revealed highly significant variation among the genotypes for all the traits studied, under both the environments. The maximum phenotypic and genotypic variance was exhibited by the traits viz., leaf area and root biomass under both the environments. | Genetic variability parameters for yield and yield related traits in rice (Oryza sativa L.) under irrigated and drought stress condition
