Abstract:

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. The heritability was recorded high for number of fertile grains per panicle, total number of spikelets per panicle, panicle density index, 1000 grain weight, leaf area, relative water content, proline content, root biomass and grain yield per plant across the environments. High heritability coupled with high genetic advance over mean was observed for fertile grains per panicle, total grains per panicle, panicle density index, leaf area and root biomass in irrigated as well as in stress condition suggesting that direct selection of these characters may be useful for future improvement of genotypes under respective environments along with improvement in drought tolerance and grain yield.
