The genetic resistance to stem lodging of cultivated oat of the Western Siberian selection with different levels of mineral nutrition in the conditions of the Northern Trans-Urals has been studied. The experimental scheme provided for three new varieties of intensive oat: Talisman, Otrada, Foma. Various levels of the agricultural background were created by applying mineral fertilizers that ensure the planned yield of 3.0, 4.0, 5.0 and 6.0 t/ha of grain. In the course of research, it was found that the Talisman variety has a tendency to lodging at the genetic level. The Otrada variety is able to withstand a yield of up to 5.0 t/ha of grain, Foma – at least 6.0 t/ha. It was revealed that the resistance to lodging has a negative correlation with the length of the upper internode (r=-0.7) and panicles (r=-0.8), as well as a positive correlation with the plant height (r= 0.8). Resistance to stem lodging by 34.3% depends on the level of mineral nutrition, 11.5% - on the genetics of the variety and 6.1% - on the growing season’s weather conditions.
