Study of biomorphological features of Phlox paniculata L. varieties from the collection of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy

The article presents the results of research on the study of biomorphological features of Phlox paniculata L. varieties from the collection of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy for the most important ornamental and economically valuable features. A methodology was developed and carried out to assess the ornamental features of some Ph. paniculata varieties to obtain breeding material promising for use in urban landscaping, as well as agro-industrial facilities and private gardening. Ornamental and economically valuable traits were considered according to the approved methodology for testing varieties for distinctiveness, uniformity and stability for two years. The tallest plants in the collection are the Zemlyanichnoe Sufle and Miss Olga varieties (on average, 70.0 cm). The most frequent leaf is green (34 varieties). The greatest length of the leaf blade was noted in the Junior Abundance and Casablanca varieties (on average 13.0 cm), the width – in the Berendey and Flamenco varieties (4.3 cm). The maximum flower diameter was found in the Faina Ranevskaya and Younique Mouve varieties (5.2 cm), inflorescence diameter – in the Flamenco variety (20.8 cm). The most frequent inflorescence shape in the studied varieties is rounded-conical (13 varieties). As a result of the assessment of the main morphological features, domestic and foreign varieties of Ph. paniculata varieties promising for breeding and producing high-quality floral products were identified: Zemlyanichnoe Sufle, Miss Olga, Knyaz Ryurik, Flamenco, Faina Ranevskaya, Chaika, Spatsommer, White Sparr, Dusterlohe, Casablanca, Darwin’s Joyce, Younique Mouve. The most ornamental variety is Darwin’s Joyce (64–75 points) characterized by a dense and compact bush, a rather strong and ornamental inflorescence consisting of large flowers of uniform, non-fading color. The possibility of using some varieties for cutting was considered.
