Unlabelled: The present study was conducted to identify the novel QTLs controlling salinity and sodicity tolerance using MAGIC rice population. Phenotyping was carried out in salinity (EC ~ 10 dS/m) and sodicity (pH ~ 9.8) at the seedling stage.

- Identification of 65 and 49 Meta-QTLs related to salinity tolerance at the seedling and reproductive stages was performed using data from 45 QTL mapping studies, involving 915 individual QTLs.
- Eight highly tolerant and susceptible genotypes were selected from a hydroponic setup to validate these Meta-QTLs, but only one microsatellite marker, "RM5635," successfully differentiated genotypes for seedling tolerance.
- The study also highlighted Os04g0423100 as a key gene linked to salinity tolerance traits, suggesting that the findings could be valuable for improving rice through marker-assisted backcross breeding.
Rice is a staple food crop in Asia and plays a crucial role in the economy of this region. However, production of rice and its cultivating areas are under constant threat of soil salinity. A major QTL, , responsible for salinity tolerance at seedling stage has been mapped on chromosome 1 using Pokkali/IR29 Recombinant Inbred Lines (RIL) population.
