Abstract: This article provides a genetic analysis of the morphobiological traits of F1-F2 plants obtained by hybridization of the intraspecific diversity of G. barbadense L. In particular, it was determined that the heredity of the photoperiodic phenotype reaction in a 15:1 ratio is regulated by the non-cumulative effect of polymer genes. Demanding for photoperiodism of the subspecies subsp. vitifolium is regulated by 3 recessive genes ph1, ph2, ph3, and a neutral reaction to a long daylight is controlled by two dominant genes Rh1, Rh2 and one recessive ph3 gene. In addition, the separation of F1-F2 plants by anthocyanin color was observed in a phenotypic ratio of 15:1 (15 plants with anthocyanin color, 1 green). When analyzing the combination of F2 f. brasiliense x subsp. vitifolium, among 212 plants examined 196 were plants with anthocyanin coloration, and stem 16 and plants were green, with ?2=0.60, P was in the range 0.50-0.20. It was determined that the anthocyanin color of plants is driven by two genes when the plant genotype was Rp Rp Rp.
Key words: photoperiodism, genetic analysis, anthocyanin coloration, heredity, intraspecific diversity, hybridization.
