QTLs and Potential Candidate Genes for Heat Stress Tolerance Identified from the Mapping Populations Specifically Segregating for F_v/F_m in Wheat.

ABSTRACT: Despite the fact that F_v/F_m (maximum quantum efficiency of photosystem II) is the most widely used parameter for a rapid non-destructive measure of stress detection in plants, there are barely any studies on the genetic understanding of this trait under heat stress. Our aim was to identify quantitative trait locus (QTL) and the potential candidate genes linked to F_v/F_m for improved photosynthesis under heat stress in wheat (Triticum aestivum L.). Three bi-parental F₂ mapping populations were generated by crossing three heat tolerant male parents (origin: Afghanistan and Pakistan) selected for high F_v/F_m with a common heat susceptible female parent (origin: Germany)
