The article reflects the results of a field assessment of nine maize inbred lines based on the intensity of grain moisture transfer in the climatic conditions of 2023. A negative correlation of this trait with the number of plants unaffected by fusarium cobs was revealed (r=-0.72). As a result of the research, a classification of the source material was carried out according to the intensity of moisture transfer of the grain and resistance to fusarium, and the two most promising corn lines were identified (MAN2084 and MAN2297).
