Rice is a staple food crop in India as well as whole world. Plant growth and productivity of rice is adversely affected by various biotic and abiotic stress factors. Water deficit is one of the major abiotic stresses, which adversely affects crop growth and yield. Water stress is a limiting factor in agriculture production by preventing a crop from reaching the genetically determined theoretical maximum yield. In present study, a pot experiment was conducted with 20 rice (1 Non Basmati and 19 Basmati) genotypes during kharif season 2018-19 and 2019-20 at field laboratory, Department of Agricultural Biotechnology, S.V.P.U.A.&T., Modipuram, Meerut, U.P., India in Completely Randomized Design (CRD) with three replications. Drought treatment was given for 10 days at flowering stage. The screening of rice genotypes was done on the basis of plant height, panicle length, seed per panicle, yield per plant, test weight and flag leaf area. The rice genotypes Nagina22 followed by Pusa Basmati 1121 showed less percent reduction in yield and yield components comparatively all other varieties. The maximum reduction in yield and other parameters under drought stress condition was observed in Basmati 386 variety. Therefore, on the basis of yield and yield component Nagina 22 showed maximum tolerance in compare to other genotypes.
