Marker-assisted pseudo-backcrossing for developing climate-resilient rice.

ABSTRACT: The increased prevalence of abiotic stresses, such as salt, submergence, and drought, severely affects rice productivity. Developing a rice variety, with inbuilt resistance to these main abiotic stresses, will contribute to a long-term rise in rice yield in adverse environments. In the present study, the rice variety Improved White Ponni (IWP) a high-yielding but highly susceptible to drought, salinity, and submergence variety was introgressed with Sub1 + SalT + DTY2.2 + DTY3.1 + DTY6.1 QTLs for improved abiotic stress tolerance. Foreground markers were employed to select the positive genotypes harboring all five in heterozygote conditions. Among the segregating population obtained from a single plant harboring all the five QTLs phenotypic selection was done to narrow down the plant number
