Identification of Novel QTLs Associated with Frost Tolerance in Winter Wheat (Triticum aestivum L.).

ABSTRACT: Low temperature (cold) and freezing stress is a major problem during winter wheat growth. Low temperature tolerance (LT) is an important agronomic trait in winter wheat and determines the plants' ability to cope with below-freezing temperatures; thus, the development of cold-tolerant cultivars has become a major goal of breeding in various regions of the world. In this study, we sought to identify quantitative trait loci (QTL) using molecular markers related to freezing tolerance in winter. Thirty-four polymorphic markers among 425 SSR markers were obtained for the population, including 180 inbred lines of F₁₂ generation wheat, derived from crosses (Norstar × Zagros) after testing with parents. LT₅₀ is used as an effective selection criterion for identifying frost-tol
