Kyrylenko V. Efficiency of the development of winter bread wheat breeding initial material with group resistance to causal agents of diseases in the Forest-Steppe.

Subject - the forming process in hibrid, populations of winter common wteat with group resistance to causal agents. Purpose - the development of breeding material of winter common wheat with group resistance to causal agents and high productivity. Methods are field and laboratory with the use of genetic , breeding and statistic ones. Value and novelty of research - the methods of winter common wheat variety development with group resistance to causal agents with the use of artificial combined infectious background of pathogens directly in the breeding process links in the Ukrainian Forest-Steppe are improved. Ten selected lines that have group resistance combined with economic characters are obtained. Introduction - the samples of winter common wheat are submitted to the National Centre of Genetic Resources of Plants of Ukraine and other institutions. The varieties of winter common wheat Ekonomka and Myronivska Storichna are developed. Field of application - breeding research institutions.
