Resistance of black mustard to fusarium wilt in the central zone of the Krasnodar region

The different diseases decreasing quantitative and qualitative yield indicators can infected black mustard as the other oil crops of Brassicaceae family. Fusarium wilt is one of the most dangerous diseases for the crop. If plants are infected with disease pathogens (fungi Fusarium spp.) in a phase of 2-4 true leaves root rot developes of young plants that causes their depth. In adult plants, conductive bundles in stems become clogged, causing premature drying of plants. Cultivation of resistant varieties is economically profitable and environmentally safe method of plant protection. The purpose of the research was to estimate new breeding material of black mustard on resistance to fusarium wilt in the central zone of the Krasnodar region. In a phase of yellow-green pod, breeding material of black mustard was estimated on resistance to the disease in a form of tracheomic wilting using 10-point scale of sample infection degree: from 0 to 9 points. All samples of mustard were divided on five group: immune, resistant, weak resistant, weak susceptible, and susceptible. During three years of research, the immune samples of black mustard were not selected. Ten samples of the crop were selected, they were resistant to the fusarium wilting on middle and high natural infection background in all years of the research. It allows recommending them to use in breeding of new black mustard varieties.
