Zhuravlyova N. Selective valuation of collection samples of winter wheat for the development of initial material in the conditions of the right-bank Forest-Steppe of Ukraine.

Object of research - new samples of winter soft wheat a different geographical origin. The purpose of research - to create an initial material for selection of a winter wheat on the basis of the allocated perspective sources of economic-valuable attributes from a genofund new collection samples of winter soft wheat from the different countries of the world in conditions of right-bank Forest-Steppe of Ukraine. Research receptions - field and laboratory methods of research of collection and hybrid materials, methods of correlation and dispersive analyses, devices for definition of quality of a grain and frost resistance samples. Theoretical results and novelty. For the first time in conditions of right-bank Forest-Steppe of Ukraine the principles of distribution of the sources of precocity, winter resistance and shortness in the different geographically distsnt forms of winter wheat were revealed. New sources of selection-valuable attributes for the use in the further breeding research were found. New hybrid material is developed.It as a result of genetic recombination combines the attributes of precocity, high winter resistance, shortness, crop productivity and high seed quality in the conditions of the right-bank Forest-Steppe of Ukraine. Practical value of the received results. Practical recommendations on the use of sources of separate and complex economic characters were developed for the involving in breeding process of the research institute of wheat the Mironovka and other institutions of the UAAS. For selection behind separate economic-valuable attributes and their complex 78 samples are recommended. 42 hybrid populations are created at attraction 31 samples from a collection of a winter wheat behind geographically remote principle of selection of pairs. Subject and introduction. Hybrids of the second generation of a winter wheat. The hybrid material created as a result of carried out researches, passes the further studying in laboratory of intensive variety of winter wheat the Scientific resarch institute of wheat named by V.M.Remeslo, UAAS, the Mironovka, in laboratory of selection and seed-growing of Agronomical station of National agrarian university and other selection establishments. Area of use are research institutes.
