Abstract

In wheat, Na+ exclusion and K+/Na+ have shown to be associated with salinity tolerance, therefore, in order to identify QTLs with additive effects for Na+ and K+ concentration traits in roots and shoots of wheat, 319 BREAD WHEAT recombinant inbred lines (RIL F7), derived from a cross between Roshan (salt tolerant) and Falat cultivars (salt sensitive), along with their parents and two control cultivars (Arg and Moghan3) were studied in two separate randomized complete block design (normal and stress) with three replications in greenhouse in 2012. Measured traits included shoot and root Na+ and K+ concentration, K+/Na+ ratio in root and shoot and root to shoot Na+ and K+ concentrations. Linkage map was constructed with 730 markers (709 DArt markers and 21 SSR markers). The linkage map spanned 4505.71 cM with an average distance of 6.17 cM between adjacent markers. A total of 31 additive QTLs were identified by QTL Cartographer program using single-environment phenotypic values. The results indicated that the biochemical pathways for Na+ and K+ accumulation are highly likely to be independent. Also, results indicated that shoot Na+ concentration and root to shoot Na+ and K+ concentrations could be used as selection criteria between tolerant and sensitive cultivars in SALT STRESS condition.
