The use the VIR world collection in the selection of new varieties and hybrids of sugar sorghum for arid regions of the Russian Federation

Relevance . Currently, a highly productive agricultural crop, unique in drought resistance, sugar sorghum is traditionally used the crop industry of agro-industrial complex mainly for fodder purposes production hay, silage, haylage, monofeed, briquettes from biomass, and recent years direction related to technical food processing has been developing. Breeders are widely attracted source material world collection VIR, on basis which new varieties hybrids created, characterized by high content juice stems, as well maturing conditions cultivation region. The multidirectional selection with specified economic characteristics relevant providing raw materials various branches complex. Methods field assessment morphometric indicators, yield biomass seeds studied samples was carried out according Methodology state variety testing crops, Broad unified classifier cultivated species genus Sorghum bicolor (L.) Moench. Results study gene pool made it possible identify 18 that donors economically valuable traits, included working creation forms. Some several signs: 6 signs — Volonter, 5 Scheherezada, k-302, L-39/12; 4 Izolda, Sahara, Seviliay, k-256, k-257, k-10092, L-66/13, L-67/13; 3 Moment, Chaika, k-327, L-44/13. According developed model results tests, Izolda isolated, surpassing zoned Volzhskoe 51 21,0% 11,1% 2020–2021.
