dc.description.abstractSoil salinity is one of the major abiotic stress having multifarious adverse effects on all growth stages of wheat. In Haryana, WH 1105 is widely cultivated wheat variety with many agronomically superior characteristics but is affected by soil salinity. In the present investigationNax1 and Nax2 genes were introgressed from Kharchia 65 into WH 1105 for salinity tolerance through marker assisted backcross breeding. F5, BC1F4, BC2F3 and BC3F1 generations of WH 1105 x Kharchia 65, were evaluated under initial salt stress condition for various morphological traits. On the basis of genotypic and phenotypic variations 57 high yielding plants of WH 1105 x Kharchia 65, were selected. Out of total 210 screened SSRs 30 markers were found polymorphic for WH 1105 and Kharchia 65. These polymorphic SSRs were utilized to produce molecular diversity among selected plants. Cluster tree analysis of parents and all the four generations of the cross, portrayed that all the selected plants were inclined toward recurrent parent WH1105 indicating higher similarity with the recurrent parent. Seven best plants were selected from the cross as high grain yielding and salt tolerant plants. These plants could be further backcrossed with the recurrent parent to develop salt tolerant wheat lines.en_US
