Results of the research - in order to isolate the genotypes of millet with valuable traits, a breeding nursery of 21 hybrids with features of technological qualities of grain (high mass of 1000 grains, optimum fluidity, high evenness of grain and spherical shape of the grain) was put together, which combined resistance in various ratios and most correlation aggressive races are Rs2, Rs3 and Rs12. In the nursery for the study of the racial-specific resistance of millet breeding material against soot against artificial contamination after evaluation of 21 hybrids with features of technological qualities of grain, 11 samples were shown, which showed resistance against the most virulent and aggressive races of Rs2, Rs3 and Rs12, as well as group resistance . All 11 lines of own breeding are not inferior to the standards on separate traits, and 4 genotypes (l.1745-04, l.1477-08, l.2098-14, l. 2155-14) were distinguished by the complex of economic and valuable features. standards for search features: anti-seizure resistance (8-8.5 points), resistance to melanosis (0%), low fluidity (13.5-15.91%), racospecific resistance to soot damage (resistant to damage 7- 11 pathotypes of soot).
