“…Nax1 promotes leaf longevity, better photosynthetic rate and stomatal conductance [ 10 ]. ‘Kharchia-65’ is a salt-tolerant variety native to the village of ‘Kharchi’ in the ‘Pali’ district of Rajasthan, capable of withstanding up to pH 9.4, making it suitable candidate for developing salt-tolerant varieties worldwide [ 11 , 12 ]. WH 1105 is a high yielding cultivar from the Northwest Plain Zone of India, resistant to yellow and brown rusts, flag smut, leaf blight and powdery mildew diseases.…”

Background Salinity is a significant abiotic stress that affects plants from germination through all growth stages. This study was aimed to determine the morpho-physiological and genetic variations in BC1F2, BC2F1 and F3 generations resulting from the cross combination WH1105 × Kharchia 65. Results A significant reduction in germination percentage was observed under salt stress in BC1F2 and F3 seeds. Correlation, heritability in the broad sense, phenotypic coefficient of variability (PCV) and genotypic coefficient of variability (GCV) were measured for all traits. The presence of both Nax1 and Nax2 loci was confirmed in twenty-nine plants using the marker-assisted selection technique. Genetic relationships among the populations were assessed using twenty-four polymorphic SSR markers. Conclusion Cluster analysis along with two and three-dimensional PCA scaling (Principal Component Analysis) revealed the distinct nature of WH 1105 and Kharchia 65. Six plants closer to the recurrent parent (WH1105) selected through this study can serve as valuable genetic material for salt-tolerant wheat improvement programs.
