Study of Spring Soft Wheat Collection Material for Economically Valuable Traits in the Conditions of Southern Dagestan

In 2023–2024, at the Dagestan Experimental Station of the Vavilov All-Russian Institute of Plant Genetic Resources, 1916 samples of spring soft wheat from the world collection of the Vavilov All-Russian Institute of Plant Genetic Resources (VIR) were studied under irrigation conditions during winter sowing for a set of valuable breeding traits. Field and laboratory assessments were carried out according to VIR guidelines. As a result of the field study, accessions of spring soft wheat with a set of valuable breeding traits and combining high grain productivity were identified. The most valuable for selection are samples that combine resistance to a complex of diseases (powdery mildew, brown rust and yellow rust) with high productivity: These are samples from Tunisia – k-16554, from Algeria – k-45177, from Spain – k-20619, from Italy – k-19643 and from Zimbabwe – k-48218.
