摘要

A study of the meiotic process in first- and second-year plants of an F_1 interspecific hybrid of Solanum linnaeum L. x Solanum incanum L. has been carried out. Fruits with seeds were obtained during the second year of vegetation. The numbers of univalents and tetravalents, as well as the percentage of basic impairments, decreased as the age of plants increased. The process of meiosis in the parental forms was normal. A conclusion was made regarding the connection between the regularity of meiosis in the F_1 heterozy-gotes of Solanum lynnaeum L. x Solanum incanum L., on the one hand, and the hybrid nature of the genotype and age and the influence of environmental factors, on the other hand.
