The aim of the project is to improve the biological knowledge of resistance to loose smut and to increase resistance against the pathogen Ustilago nuda, especially for organic farming. Therefore, suitable resistance traits will be identified from genetically diverse material and transferred into elite varieties with excellent agronomic and qualitative properties in an optimized crossing approach. First, the aggressiveness of loose smut isolates of different origins will be evaluated based on a differential set. In addition, existing elite varieties and hundreds of barley genotypes from a highly diverse, worldwide collection including genetic resources will be screened for susceptibility to loose smut and analyzed for genotype-barley × genotype-smut interactions. Based on these findings, bi-parental mapping populations will be established by crossing resistance donors with non-resistant genotypes. These populations will be used for the genetic mapping of resistance to loose smut and allow to infer molecular markers. Closely-linked molecular markers will facilitate efficient selection of resistant genotypes and pyramidization of different resistance genes in the future. The project supports breeding of new cultivars with improved resistance to loose smut for both organic and conventional agriculture and contributes to the reduction of plant protection chemicals. It can thus make an important contribution to the implementation of the European Green Deal. Through introgression of resistances to loose smut into breeding material with high yield potential and excellent quality traits in terms of feed suitability and seed quality, an important contribution will also be made to the quality assurance of the winter barley cultivar spectrum.
