Abstract
A cytogenetic analysis of the seed progeny of Pinus sylvestris L. trees growing in the Voronezh Oblast during differing weather conditions (optimal and drought) was performed. It was established that in the years of drought frequency of mitosis pathologies level increased, but did not go beyond the norm. The spectrum of pathologies in these years is expanded, but should be assumed that some of them may contribute to the reallocation of genetic material between chromosomes, that in turn would expand the range of reaction norm of the organism, thereby improving its ability to adapt to changing environmental conditions.
