Formation of husker grains in naked oat lines

The research was carried out in 2022–2024 at the Federal State Budgetary Budgetary Institution FANTS of the North-East. The purpose of the research is to study the naked oat breeding lines of the FANTS of the North-East for the formation of grain with husk under unstable climatic conditions of the Kirov region. It was revealed that all genotypes formed of grain with husk, their quantity depended on weather conditions by 42.3 %. Favorable conditions for the formation of grain with husk of were formed at an average daily air temperature of 18.6 °C during the period “stooling – milk maturity”, and at an air temperature of 19.7 °C, the 61h21 and 4h18 lines had only husker grains. The formation of grain with husk was facilitated by drier conditions during the “seadling – tillering” and “tube–sweeping” periods with precipitation totals of less than 15 mm. A weak reaction
