Object: the enrichment of genetic diversity in common wheat on the basis of mobilization, introduction, identification and documentation of the world gene pool. Aim: the substantiation of the theoretical bases of using common wheat genetic resources in plant breeding, research and educational purposes, and the formation of base and evaluation collections on the basis of establishment of regularity of display of valuable signs. Methods: general scientific, field, measuring and weighing, laboratory and statistical. Novelty: for the first time in Ukraine a scientific problem enrich the genetic diversity of common wheat is theoretically proved and solved. The regularities of valuable characteristics appearance depending on environmental and geographical origin of samples were evaluated. Priorities of introduction were distinguished on this base. The connections between appearance of different parameters and ranges in which reached maximum levels of productivity and other quantitative features were detected. Arrays of the obtained data were processed by methods of cluster and factor analysis. On this basis, a reduction of the data was conducted, the main components were highlighted, and relationship between the regions of origin and the samples were found. Samples of collection were grouped by level of environmental plasticity. Methodological approaches to study genetic resources and summarizing its results were improved. The use of protein markers for the identification of grain quality traits and identified patterns of occurrence of allelic variants of storage proteins, depending on environmental and geographical origin are further developed. Results: sources of complex important traits were identified. They were introduced into breeding practice and genetic research and used in the creation of new source material for breeding. Basic and trial collections with appropriate databases were formed for highly efficient use of wheat genetic resources in theoretical and applied research. Degree of implementation: the identified and created sources of some valuable traits and their combinations were transferred to customers - the total number over 19,000 packages, some of which are used in theoretical studies, breeding practices, varietal trials and the learning process (Institute of Plant Physiology and Genetics NAS, Ukrainian Institute of Expertise of Plants Varieties NAAS, Plant Production Institute NAAS, Institute of Plant Breeding and Genetics NAAS, Southern Center for Biotechnology NAAS, Poltava State Agrarian Academy, Sumy National Agrarian University and other local and foreign institutions). In collaboration with the participation of the applicant two varieties of winter bread wheat Astet and Poverna established and implemented in the agricultural production, 7 more varieties of wheat and triticale submitted to the state trials. Field of Study: academic institutions of NAAS and NAS of Ukraine, the agricultural enterprises of all forms of property in Ukraine.
