- Spring bread wheat is a key crop in Russia and Kazakhstan, heavily impacted by rust pathogens like leaf, stem, and yellow rust.
- A study tested 40 new wheat genotypes for their resistance to these rusts and identified several with significant resistance, including three that were resistant to all rust types.
- Molecular analysis revealed both cataloged and uncataloged resistance genes, indicating improved resistance and genetic diversity in the new wheat genotypes due to the introduction of alien genetic material.
The two recombinant inbred line (RIL) populations developed by crossing Almaly × Avocet S (206 RILs) and Almaly × Anza (162 RILs) were used to detect the novel genomic regions associated with adult plant resistance (APR) and seedling or all-stage resistance (ASR) to yellow rust (YR) and leaf rust (LR). The quantitative trait loci (QTLs) were detected through multi-year phenotypic evaluations (2018-2020) and using high-throughput DArTseq genotyping technology. RILs exhibited significant genetic variation with < 0.

The development and cultivation of resistant genotypes is the most efficient control method. The present study was conducted to explore the yellow rust resistance potential of modern common winter wheat cultivars included in the Russian Register of Breeding Achievements in 2019-2022 using the seedling tests with an array of races and molecular markers linked with resistance genes.
