Abstract:

A field screening of thirty four drought tolerant rice genotypes was conducted during Kharif 2017 and Kharif 2018 with the objective to identify different genotypes under drought stress condition. Significant variation was observed among genotypes for all studied traits including leaf rolling, leaf drying and relative water content. The tolerant lines maintained high leaf water status, membrane stability and plant biomass under reproductive stage drought condition. All thirty four genotypes were distributed in nine clusters. Out of thirty four genotypes seventeen were placed in cluster I, eight in cluster II, three genotypes in cluster III while in rest of the clusters are mono genotype. The findings of this study indicate that the cluster III, IV, VI, VII and IX showed the higher distance under drought stress condition.
