Annotation

Chrysanthemum × hortorum is an important flower-decorative culture. The collection of garden chrysanthemum of the Federal Research Centre the Subtropical Scientific Centre of the Russian Academy of Sciences is represented by 62 varieties of domestic and foreign breeding, as well as more than 200 hybrids obtained at the Centre in different years. Since 2006, breeding studies have been carried out at the FRC SSC RAS, the purpose of which is to create decorative, adaptive, productive varieties with different flowering periods, unusual shapes and colors of inflorescences for universal use. Objects of research are a hybrid fund obtained from 10 combinations of inter-varietal crosses and 7 groups of hybrids from free pollination with known maternal varieties. As a result of the research, the nature of the inheritance of decorative features of the inflorescence, such as the type of calathid, the shape and color of the ray flowers, as well as the shape of the leaves, was determined. It has been established that 80 % of seedlings from the studied combinations have inflorescence color different from parent varieties. The form of ray flowers in most cases is a neoplasm. The leaf shape of most hybrid seedlings in 70 % of the studied crosses differs from the original parental plants. Hybridological analysis of the offspring made it possible to identify promising combinations of crossing, such as: ♀ 'Izetka Bernstein' × ♂ Zh-10-10, ♀ 'Izetka Bernstein' × ♂ M-187-1, ♀ 'Mona Lisa White' × ♂ M-182- 1, ♀ 'Sadko' × ♂ 'Amber', ♀ 'Amber' × ♂ 'Sadko', 'Amber' × 'Sadko', 'Symphony' × 'Tigerreg'. Varieties 'Harlequin', 'Symphony', 'Mona Lisa White', 'Izetka Bernstein', 'Sadko' were selected as sources of economically valuable traits.
