Meiosis passing in the first- and second-year-plants of F1 interspecific hybrid Solanum linnaeum L. Ч Solanum incanum L. has been carried out. Fruit with seeds were formed during a second year of vegetation. The quantities of uni- and tetravalents and main disorders frequency lowered with plant age. Meiosis in parental forms was normal. The conclusion was drawn about F1 Solanum linnaeum L. Ч Solanum incanum L. meiosis regularity connection with heterozygous genotype, influence of environmental factors and plant age.

Key words: Solanum linnaeum L., Solanum incanum L., F1 hybrid, bud, meiosis, meiotic disorders, chiasma, tetravalent, univalent
