title: [Process of meiosis in interspecific hybrid F1 Lycopersicon esculentum Mill. x Lycopersicon chilense Dun].
abstract: The investigation concerns meiosis behaviour in embryo-culture-obtained Lycopersicon esculentum Mill. (mutant seedline Mo 638) x L. chilense Dun. F1 hybrid and its parental forms. It was determined that chiasma frequency decreased while univalent and meiotic disorder frequencies increased in F1 plants in comparison with parents forms. Univalent number and the percent of main disorders lowered with bud tier increasing. The conclusion was made about meiosis regularity connection with the influence of environment factors and heterozygous genotype of F1 plants Lycopersicon esculentum x L. chilense.
