The article examines the features of self-pollination in certain species of the genus Crataegus L. under conditions of introduction (Arkhangelsk). Studies conducted in 2023 and 2024 showed that self-pollination results in few or no fruits being formed, and mainly produces empty seeds. Under free pollination, it was noted that the quality indicators are somewhat higher, but still remain low, which is characteristic of the genus Crataegus L.
