Breeding and seed production of soft winter wheat. The purpose of the work. Obtaining new knowledge about the genetic composition of sorts and varieties of soft winter wheat, identifying donors of economic and valuable features by using methods of classical selection with the involvement of molecular genetic markers, statistical analysis. Creation of the source material of winter wheat, studying and selection of plants in breeding nurseries. In-depth study of candidates for varieties on the basis of plant resistance to biotic and abiotic factors, yield and quality of grain. Research methods. Creation of the source material by hybridization method with the use of spring and winter forms of soft wheat and the use of other types of wheat. Study of breeding material according to the complete scheme of breeding process. Study of the stability of samples against rust diseases in the field and laboratory - the identification of genes with the help of molecular genetic markers. Determination of grain quality indices on Infratec 1241 and SDS-30 devices. Research results and their novelty. A new breeding material was created according to the task and hybrid combinations of I-III generations in four areas of research in the volume of 300 combinations of crossing F1 based on the evaluation of elements of productivity, winter resistance, resistance to harmful diseases and lodging, grain quality indices and identification of valuable genotypes by means of PCR analysis and electrophoresis of spare proteins. The best lines of the control nursery, preliminary and competitive variety testing in each research point are allocated. Selected lines that provide a high yield increase in all points. In 2016 were transferred to the State variety testing new varieties of soft winter wheat Zaotar, Osyaina, Rusyava, Prestigna. Product Description popup.authors Буряк В.Ю. Голик Л. М. Заїка Є.В.
