AGRICULTURAL AND BREEDING PREREQUISITES FOR SUCCESSFUL INTRODUCTION OF MIRONOVKA WINTER WHEAT VARIETIES IN THE USSR AS THE BASE FOR INTRODUCING NEW VARIETIES RESISTANT TO SIBERIAN WINTER

Abstract

A broad gene pool has been obtained at the Institute of Cytology and Genetics on the base of the comprehensive  study of frost resistance in wheat supervised by Dr. V.M. Chekurov. The wheat accessions demonstrate both great manifestation of winter resistance and other commercial traits characteristic of cultivars. Therefore, many accessions have been certified as cultivars. They are grown in Siberia. As shown by the experience of the Mironovka Institute of wheat selection and seed production in the USSR, the large scale of the use of varieties raised at the Institute was determined by their winter resistance and the development of varietyoriented technologies, depending on the climatic belt, soil, rotation of crops, watering mode, etc. In our opinion, extensive growing of the new varieties is greatly hampered by the absence of such technologies for Siberia. Recommendations developed by scientists of the Mironovka Institute and the need for their adaptation to Siberian regions are discussed.
