New knowledge was obtained about the activity of photosynthesis, resistance to extreme environmental factors and consumer qualities of grain from promising varieties and lines of spring wheat. It is concluded that in spring wheat selection the work focused on the creation of varieties with high activity of leaves photosynthesis can be effectively conducted, using effectively the identified sources of the properties of the genotypes. The selective material of winter wheat in hybrid and selective nurseries is studied, intraspecific and interspecific hy-bridization is conducted, the hybrids are studied and selections from hybrid populations are performed, the offspring is evaluated on economically useful characteristics. On the basis of the study, preliminary conclusions are made and the selective material to create new varieties of winter wheat is received.
