Selection and seed production of winter rye. The purpose of the work. To allocate and transfer to the state variety trial a new variety of winter rye with a potential yield of 7.0-8.0 t/ha, with a high-yielding ear, three-grain spikelet in the ear instead of two-grain; select plants on the basis of the multiflowerness of the ear. Research methods. The research was conducted using generally accepted selection methods. The processing of breeding material was carried out according to the complete scheme of breeding process. All observations and evaluations of breeding material in nurseries of different levels were carried out according to the method of state variety testing. Research results and their novelty. The forms were selected in the breeding and control nurseries on the basis of the multiflowerness of the ear with the following indices: productivity - more than 8 points, resistance to diseases 8 points, winter resistance 8 points, drought resistance 8 points, lodging resistance 8 points, protein content 13.5% and more for establishing a level of penetrance of a sign. The best numbers of winter rye, which had an increase in yield from 0.1 to 0.6 t/ha, were selected in the previous and competitive variety tests, of which four exceeded the standard on yield at a reliable level.
