АннотацияThe authors made the phenotypic, genetic-selective and molecular RAPD-analysis of genotypes of progeny of transgenic interspecific hybrid of tomato of Lycopersicon esculentum Mill. (the Fakel variety) × Solanum pennellii Cor. The high genetic variability was revealed in studied variants both on molecular and phenotypic level. Selected tomato forms are of interest for practical breeding.

The high genetic variability was revealed in studied variants both on molecular and phenotypic level. <...> Selected tomato forms are of interest for practical breeding. <...> Keywords: interspecific hybrid of tomato, coadapted blocks of genes, spectrum genotypic variability, alien exogenous DNA. <...> Creation of cultivated plant species with improved adaptability necessitates the transfer into their genomes of wild species’ chromosome loci or groups of coadapted genes for economically valuable quantitative traits (1). <...> Consequently, a practical use of the wild species’ gene pool requires effective methods for increasing the available range of genetic and genotypic variability, which is one of the most important tasks of contemporary selection. <...> Previously, the authors have obtained the transgenic interspecific hybrid of tomato Lycopersicon esculentum Mill. (Cv. <...> Its paternal form was the species-source of valuable adaptive traits - cold hardiness and resistance to a number of viral and bacterial diseases (3). <...> A distinctive feature of this hybrid is its genotype carrying foreign DNA for resistance to kanamycin introduced into the germinating pollen during a natural pollination–fertilization (2). <...> The purpose of this work was to estimate breeding, genetic and molecular features of genotypes in a splitting population of the transgenic interspecific hybrid of tomato carrying foreign exogenous DNA. <...> The object of study were transgenic plants the interspecific hybrid of tomato L. esculentum Mill.
