Search for promising genotypes to regulate lipid complex in grain during targeted oat breeding

The aim of the study is to evaluate the collection of hulled and naked oats for oil content to identify promising parental forms for targeted selection. The studies were conducted on an experimental field located in the northern forest-steppe of the Trans-Urals. The collection was represented by 106 genotypes of domestic and foreign selection, of which 80 belonged to the hulled subspecies, 26 to the naked one. In the grain of naked samples, the oil content varies from 4.4 to 8.7 %, while in hulled ones it is 3.3-7.4 %. The minimum oil content was recorded in the naked forms: Large hulless × Red rustproof, Sibirskij golozernyj, Numbat, Sallust, Pomor - an average of 4.4-4.7 %. Among the filmy genotypes, the following were distinguished: Marshal, Foma, Prem'er, Eklips, Uralec, Pamyati Bogachkova, Atlet, Sibirskij kormovoj, which had oil content within 3.3-4.1 %. The listed genotypes were characterized by minimal variability of oil content in grain over the years, which makes them promising for breeding aimed at creating new varieties for food purposes. In the studied collection, genotypes with the maximum oil content in grain were noted. Among the naked varieties, these are Samson 57, Azil', Tajdon, Vyatskij golozernyj - the lipid content in the grain was maximum - 7.7-8.7 %. Among the hulled varieties: FF 64-74, Wandering, Grajcar, L'govskij 82, Korifej, Slawko, PJ 244467, Vista, Ulov, Pc 96, AC Rebel, Petrovich - the oil content varied from 5.6 to 7.4 %. These genotypes are promising for breeding oat varieties for grain feed.
