PROMISING HYBRID FORMS OF CROWN ANEMONE, CREATED IN HUMID SUBTROPICAL CONDITION

Crown anemone (Anemone coronaria L.) is a representative of the buttercup family (Ranunculaceae). One anemone flower blooms for 7–9 days on average, and the plant blooms for up to two months. Its flowers are diverse in color and have a plane, semidouble and double shape of the perianth. The cultivars collected in FRC SSC of RAS were imported from the Netherlands, but did not have a sufficient adaptability to adverse weather conditions in the subtropical climate (the Black Sea coast of the Caucasus). Russian cultivars are being created using the methods of interparietal and interspecific hybridization. For competitive cultivar trial among hybrid forms of crown anemone, the experiment is laid in three repetitions. The number of tubers in one repetition is 25–30 pcs. In order to compare the characteristics of hybrid forms, zoned anemones collected in FRC SSC of RAS have to be planted. The period from seedling emergence to flowering of the studied crown anemone hybrids and their control cultivars is from 13 to 16 weeks during autumn planting. From the presented crown anemone hybrids, this development phase has been recorded as the shortest in the hybrid form G-13-162 (13.6 weeks), and as the longest in hybrids P-6-6 and P-2-11 (15.4 weeks). The earliest flowering among the studied hybrids has been noted for the form G-13-162 (April 7). The duration of flowering among the hybrid forms presented in the table averaged 56 days (8 weeks), and among their control cultivars – 50 days (7 weeks). The height of crown anemone’ peduncle determines the product category (cut), so this indicator is taken into account when studying the hybrid forms obtained. The height of the hybrid forms’ peduncle is on average 9.4 cm (34.4 %) higher than that of the control cultivars.
