Abstract:
The current study was carried out during 2023 at Department of Rice, CPBG, TNAU, Coimbatore, intending to phenotypically screen the BC3F2 population derived from a cross between CO 52 and APD 19002 against salinity and drought. Salinity screening was done at seedling stage and drought screening was carried out in reproductive stage. Total of 240 BC3F2 plants were utilized from three different high genome recovered plants. These plants are subjected to12 EC and visual salt injury score was taken based on modified SES score given by IRRI. 25% plants were survived from the seedling stage salinity stress. These plants are forwarded to screen for reproductive stage drought stress and leaf rolling, leaf drying and senescence score was taken. In that 90% plants were survived. Eleven plants are identified as tolerant for both salinity and drought based on the score. The selected plants may play a crucial role in addressing the challenges posed by climate change and ultimately benefiting both farmers and consumers.
