Online Published on 14 August, 2024. Abstract Thirty-eight genotypes of basmati rice were evaluated to identify drought-tolerant genotypes by using leaf rolling and leaf senescence scores under drought conditions, and further validation was done with PCR studies using drought tolerance genes. The genotypes Taravadi, Pusa Sugandh-5, Hariyana Basmati-1, Hariyana basmati-2, Palim basmati, Vallabh Nagina-1, Ranbir basmati, Sanwal basmati, Vallabh basmati-21, Vallabh basmati-22, Vallabh basmati-24, Kasturi, Malviya and Type-3 were found as suitable drought tolerant genotypes. The selection criteria based on leaf rolling and senescence could be useful for breeding drought-tolerant genotypes of basmati rice.
