Breeding and seed production of soft winter wheat. The purpose of the work. To create a variety of winter wheat with the use of methods of classical breeding and technological, with the involvement of molecular genetic markers and statistical analysis, adapted to the conditions of Polissya and northern Forest-steppe of Ukraine. Selection in the selection and control nursery of numbers that can be donor of high productivity, early ripeness and resistance to rust diseases. Research methods. Creation of the source material by hybridization method with the use of soft and winter wheat and winter wheat forms and the use of other types of wheat. Study of breeding material according to the complete scheme of breeding process. Studying the stability of samples against rust diseases in the field and identifying genes with molecular genetic markers. Determination of grain quality indices on Infratec 1241 and SDS-30 devices. Research results. An estimation of winter resistance of varieties and lines of control nursery, preliminary and competitive variety testing was conduct. It was evaluated for resistance to powdery mildew, Wheat leaf rust for numbers of breeding, control nurseries and the lines of preliminary and competitive variety testing. Selected in the breeding and control nursery rooms, which can be donor high yield, quickness and resistance to irregular diseases. A new selection material is created according to the task and hybrid combinations. The analysis of F2 hybrids on the allelic state of the Wx-A1, Wx-B1 and Wx-D1 genes was performed. The best lines of the control nursery competitive variety testing are selected. Bread was made from 50 lines and the best lines were selected. Product Description popup.authors Буряк В.Ю. Голик Л. М.
