On the new forms of perennial phlox (Plox paniculata - Polemoniaceae)

The aim of the study was to select seedlings of Phlox paniculata L. with the most decorative features and crop-stable, their description. Research objectives are: to provide conditions for cross-pollination of parent plants, the formation of fruits and full-fledged seeds, selection of conditions for seed germination and successful growth of seedlings, selection of the most decorative and resistant forms, monitoring the biological characteristics of selected plants. Observations were carried out from 2014 to 2020. As a result, 12 seedlings were selected, which are characterized not only by high decorativeness, but also by resistance to adverse factors, originality and ease of vegetative reproduction. The paper gives a diagnosis and highlighted the typical material for 12 cultivars, of which 3 have a rich, bright color - Zharovsk (red), Nadezhda Alexandrovna (red-purple), Igor Krom (violet-purple); 6 - a peculiar color and shape of the flower - Polkovnik, Nadezhda Antonova, Shuravi, Perlamutr, Mozharka, Tanzybeyskiy Sitetz; 5 - large, massive inflorescences - Belaya Panama, Professor Schweingruber, Polkovnik, Afganetz, Mozharka; 2 - large flowers - Nadezhda Alexandrovna (up to 5 cm in diameter), Perlamutr and Shuravi (up to 4.5 cm); 2 - long flowering period (early July - first half of August) - Nadezhda Alexandrovna, Polkovnik; 6 - early flowering dates (first half of July) - Nadezhda Alexandrovna, Mozharka, Belaya Panama, Perlamutr, Professor Schweingruber, Afganetz. All cultivated varieties are resistant to the climate conditions of Southern Siberia, unfavorable factors. For new cultivated varieties, photographs and information about their features (size and shape of inflorescences and flowers, corolla color, height and habit of plants) are given. Information about the most similar varieties and their differences is given. The largest number of valuable cultivars was obtained from the old varieties of Phlox paniculata: Uralskiy Samotsvet, Rumyany, Chernomor, Novinka.
