Abstract

Using genomic in situ hybidization, among the common wheat cultivars produced in West Siberia (Siberian Research Institute of Agriculture, Omsk) with the involvement of the winter wheat cultivar Kavkaz carrying the wheat-rye 1RS.1BL translocation we identified three cultivars with this translocation: Omskaya 29, Omskaya 37, and Omskaya 38. The protein and crude gluten contents in the grain of these cultivars are equal to or exceed the levels observed in cultivars without the wheat-rye translocation. The common wheat cultivars carrying the wheat-rye translocation were evaluated in terms of resistance of plants reaching wax ripeness to leaf rust and powdery mildew in the natural field conditions. The cultivars Omskaya 37 and Omskaya 38 displayed a high field resistance to leaf rust and were resistant to a variable extent to powdery mildew. The cultivar Omskaya 29 was susceptible to leaf rust and powdery mildew pathogens. Importance of the selection direction and the role of the genetic background in developing common wheat cultivars carrying the wheat-rye translocation is discussed.
