PROTEIN POTENTIAL OF NAKED OATS IN THE CONDITIONS OF THE FOREST-STEPPE ZONE OF THE TRANS-URALS

The research was carried out in order to identify high-protein genotypes of naked oats for inclusion in the breeding program to create varieties that are maximally adapted to the conditions of the forest-steppe zone of the Trans-Urals. The object of research was 105 genotypes of naked oats from 19 countries, including 34 of domestic origin. The Tyumen nudibranch was used as the standard. The study took place in 2022–2024 in the Northern Trans-Urals. The soil is dark gray forest, rejuvenated, medium loamy. The availability of nitrate nitrogen is low, and mobile phosphorus is medium. The protein potential was determined by a set of indicators: the content of crude protein in grain, yield, protein yield per 1 ha. Genotypes Large hulless × Red rustproof, Korolek, Pele, UFRGS 106150-3, Sallust, Ba you 14, Local (k-2468, k-4958, k-8427), L 1004-6(479), Belor, MF 9714-32, MF 9714-36, MF 9224-164, Line 120 1/29, Ljusy, Avoine nue rennes, MF 9621-280, Bai yan 1 in the conditions of the Trans-Urals, grains with a crude protein content of more than 17.0 % are formed, while Tyumen nudibranch – 14.9 %. 43 genotypes were identified, whose yield was more than 10 % higher than the standard. There was no correlation between the productivity of the genotype and the protein content in the grain. As a genetic source of high protein content of grain (protein content >17.0 % and coefficient of variation <15 %) of oats, we recommend using MF 9621-280, line 120 1/29, MF 9714-36, MF 9714-32, Mestnji (k-4958). The most promising genotypes with protein productivity exceeding the standard by 20 % or more were identified: Pele; Ba you 14; Line 120 1/29; L 1004-6(479); MF 8891-2021; MF 9224-164; Belor; UFRGS 106150-3; MF 9714-36; MF 9714-32, which are recommended to be included in the breeding program for the creation of high-protein cultivars of naked oats.
