Varieties with salinity tolerance at seedling stage promote an efficient growth at early stages in salt affected soils, leading to healthy vegetative growth that protects crop yield. Saltol major QTL confers capacity to young rice plants growing under salt condition by maintaining a low Na⁺/K⁺ molar ratio in the shoots.<h4>Results</h4>Marker-assisted backcross (MABC) procedure was adopted to transfer Saltol locus conferring salt tolerance at seedling stage from donor indica IR64-Saltol to two temperate japonica varieties, Vialone Nano and Onice. Forward and background selections were accomplished using polymorphic KASP markers and a final evaluation oRice (New York, N.Y.)Marker-Assisted Introgression of the Salinity Tolerance Locus Saltol in Temperate Japonica Rice.PMC9837369Grant Agreement N. 678168Gavina GVale GNogues SCourtois BBrottier LFrouin JFinocchiaro FTondelli ANegrini NGrenier CZampieri ETacconi GPesenti MBundo MSerrat XCavallaro VSacchi GASan Segundo BCattivelli LMare CMonaco SBovina RfalseMarker-Assisted Introgression of the Salinity Tolerance Locus Saltol in Temperate Japonica Rice.<h4>Background</h4>Rice is one of the most salt sensitive crops at seedling, early vegetative and reproductive stages.
