Ya. Yuriev of the National Academy of Agrarian Sciences of Ukraine popup.description1 Purpose – to genetically and breedingly improve nutritional properties of winter wheat, to identify sources, to establish inheritance patterns of grain quality indicators in bread wheat, and to create environmental stressor-adapted varieties popup.description2 The object of the study is the breeding process of soft winter wheat. The aim of the study is to create new valuable source material adapted to the conditions of Ukraine, highly productive varieties of soft winter wheat based on the identification of sources and the establishment of patterns of inheritance of grain quality traits. Research methods: field, laboratory, statistical. Scientific value and relevance of the results obtained: the involvement of genetically related wild species in hybridisation makes it possible to include new sources of resistance to diseases and pests, winter hardiness, quality, and increased nutritional value, and will allow the creation of winter wheat varieties with high nutritional properties that are adaptable to environmental stress factors. In 2021–2025, new breeding material was created by hybridisation, resulting in 1,055 hybrid combinations. In F1 and F2 hybrid nurseries, about 2,700 hybrid combinations were studied, and individual selections of more than 120,000 ears were made. A total of 63,162 numbers were studied in the breeding nursery. Careful evaluations and individual selection of the best families from the breeding nursery allowed 7,820 lines to be selected for the control nursery. In the preliminary variety testing, 1,792 lines were studied, and in two competitive experiments, 475 lines were studied. Over five years, 2,174 analyses were conducted to determine the protein content in grain, 1,603 to determine the sedimentation index, 930 to determine the rheological properties of dough, and 460 to determine the overall baking quality. 65 lines created from the collection, control nurseries, and preliminary variety testing were analysed for carotenoid content. During 2021-2025, two working collections were formed, and four lines with identified Psy-A1a and Psy-B1c alleles were transferred to the NCGR, and 6 lines of soft winter wheat created with the participation of related species of different types of development Product Description popup.authors Kateryna Y.
