SELECTION OF INITIAL MATERIAL FOR SELECTION OF MILLET IN CONDITIONS OF THE STEPPE ZONE OF KBR

Abstract

The object of investigation is millet samples from the VIR collection, Cheget’s millet varieties, Elbrus 10 and the Caucasian Zori of the Institute’s selection, as well as lines that have a decent adaptability to the bio and abiotic factors of the environment. In the course of the work, experimental studies were carried out to identify and use sources of valuable features and properties. As a result of the research, new highly productive large-grain, drought-resistant millet samples were first isolated, exceeding the crop yield standard by 3.0-9.2 c / ha. The methods of selection of parental pairs were analyzed. It has been revealed that as a maternal form it is better to use local drought-resistant, heat-resistant samples in crosses, and as a paternal plant, foreign varieties with less heat resistance, drought resistance, but high productivity, resistance to lodging, shedding of grain, diseases, The Caucasian dawns have been created and approved for use in the Southern Federal District. The assessment of energy efficiency, as the final stage of scientific research, attests to the high efficiency of cultivating a new millet grade of Caucasian dawns and is 4.4. To create highly productive millet varieties, it is necessary to use close correlation links of such characteristics as drought resistance, heat resistance, productivity, resistance to lodging and diseases. In agricultural production it is necessary to use the sorts listed in the State Register of Selection Achievements of the Russian Federation: Cheget, Elbrus 10, Caucasian Dawns. Field of application: plant growing.
