Lines derived from spring bread wheat Omskaya 37 and possessing wheat-rye translocation 1RS.1BL have been studied and tested for resistance to fungal pathogens, drought, crop yield, and parameters characterizing ecological plasticity and stability. Three lines have been studied with the use of the C-banding technique. It is shown that these lines, in addition to wheat-rye translocation 1RS.1BL, possess wheat-wheatgrass translocation 7DL-7Ai, where a segment of chromosome 7Ai of Agropyron elongatum (= Thinopyrum elongatum ; = Thinopyrum ponticum ) is translocated to the long arm of wheat chromosome 7D. It is concluded that the complex resistance of Omskaya 37 and its promising lines is related to the influence of a cluster of genes located on segments of rye and Agropyron chromosomes involved in the respective wheat-alien trans-locations. Several promising lines are recommended for further use in breeding programs. One of the lines we consider here, Lutescens 242/97-2-10, is submitted to a state variety trial for registration as the spring wheat variety Omskaya 41.
