The results of the investigations of resistance winter common wheat varieties to leaf rust are given. The high resistance to the pathogen manifest varieties that contain resistance genes: Lr9, Lr19, Lr37, Lr42 + Lr24, Lr43 (Lr21 + Lr39) + Lr24, Lr9 + Lr26, Lr10 + Lr24 are ascertained. The genes Lr13, Lr34, Lr37 in combination with other resistance genes provides long-term protection to leaf rust wheat. Winter wheat varieties, created at the V. M. Remeslo Myronivka Institute of Wheat, contain resistance genes Lr23, Lr24, Lr26, Lr34. The varieties Vesta, Snizhana, Demetra are protected by the resistance genes Lr26 + Lr34, variety Zolotokolosa– Lr24 + Lr34, Ekonomka – Lr3 + Lr26, Myronivska storichna – Lr3 + Lr23 + Lr10 + Lr26. The allele Lr34 (+) is contained in varieties: Kryzhynka, Vesta, Snizhana, Volodarka, Demetra, Vdiachna, Pamiati Remesla, Sviatkova, Podolianka, Berehynia myronivska, MIP Dniprianka, and Balada myronivska. Sustainability is an important element of an integrated system of plant protection against many diseases, and to ensure increased yields it is necessary to create and distribute sustainable varieties that will be an environmentally promising way to develop the agro-industrial complex of Ukraine.
