The genetic architecture of resistance to septoria tritici blotch in French wheat cultivars.

ABSTRACT:

Background

Septoria tritici blotch (STB) is one of the most damaging wheat diseases worldwide, and the development of resistant cultivars is of paramount importance for sustainable crop management. However, the genetic basis of the resistance present in elite wheat cultivars remains largely unknown, which limits the implementation of this strategy. A collection of 285 wheat cultivars originating mostly from France was challenged with ten Zymoseptoria tritici isolates at the seedling stage. The collection was further evaluated in seven field trials across France using artificial inoculation.

Results

Genome-wide association study resulted in the detection of 57 wheat QTL, among which 40 were detected at the seedling stage. Three quarters of these QTL were in genomic regions pr
