Promising spring durum wheat lines resistant to brown rust in northern Kazakhstan

The breeding of spring durum wheat varieties resistant to leaf rust is considered a topical issue. The aim of our research is to identify promising spring durum wheat lines resistant to leaf rust with a complex of economically valuable traits. In 2022-2024, 163 spring durum wheat lines were studied for resistance to brown rust, growing season, grain yield, specific weight, vitreousness, and protein content. Immunological evaluation of spring durum wheat varieties was carried out using standard laboratory methods on seedlings grown in a greenhouse. The physical and physicochemical properties of the grain were evaluated using standard methods. The selected spring durum wheat samples will be recommended to breeders as sources of resistance to leaf rust, as well as sources of high quality for the creation of new competitive varieties adapted to the conditions of Northern Kazakhstan.
