Nine significant marker-trait associations related to Zymoseptoria tritici resistance were identified in soft winter wheat.
Notable MTAs were located on chromosomes 1A, 4A, 5B, and 6A, some corresponding to known resistance genes.
The study analyzed 337 wheat genotypes inoculated with Zymoseptoria tritici to assess resistance traits over time.
Identifying both novel and known sources of resistance offers potential for enhancing wheat breeding programs.
