When developing the new varieties of food use are developed the dominant trend in breeding is adaptive direction to realization of properties complex in genotypes. Using evolution and statistical approach as well as breeding work in the region there were developed optimal parameters of winter wheat morphotypes for the conditions of the Republic of Belarus and were substantiated the indices of development of the properties in new varieties of food use for three productivity levels: middle intensive, intensive and high intensive. These varieties will posses optimal morphophysiological parameters and will be characterized by even foliage, high density of stand, middle and high grain size, high grain content in an ear and intensive grain filling. the decision of ecological breeding in the Republic of Belarus can be used by the example of the system of winter wheat varieyies with different adaptivity levels where valuable crop properties are centered. the varieties have been applied in industry and now they cover 80% of crop sown area in the region
