THE INTRODUCTION OF DWARF BEARDED IRISES IN SOUTH-URAL BOTANICAL GARDEN-INSTITUTE

The article presents the results of the study of introduced varieties of dwarf bearded irises (Filippok, Deep Lavender, Bright White, Cherry Garden, Clash, Well Suited, Banbury Ruffles, Skip Stitch, Inscription, April Accent, Lace Caper, Double Lament) on the basis of the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of Russian Academy of Sciences. The main purpose of the study was to replenish the collection of the genus Iris with new varieties from the classes MDB (miniature dwarf bearded irises) and SDB (standard dwarf bearded irises), their introduction and selection of the most valuable cultivars suitable for introduction into production, as well as for use in breeding. Seasonal rhythm of plants was studied by the method of phenological observations. The assessment of decorative features was carried out according to the generally accepted «Method of state variety testing of decorative cultures», and also used the scale of comparative variety evaluation developed by the Main Botanical garden. As a result of the phenological observations revealed that the timing of flowering all studied of irises, except for the variety Skip Stitch, attributed to the early flowering – the beginning of flowering is observed in May. The earliest onset of the flowering phase was observed in the variety April Accent (May 21); at the latest – in the variety Skip Stitch (June 03). The duration of the flowering phase ranged from 10 (‘Inscription’) to 27 (‘Lace Caper’) days. The life of the flower from disclosure to wilt averaged from four to six days. It was found that in the forest - steppe zone of the Bashkir Ural half of the studied varieties undergo a full cycle of development: they bloom and bear fruit, the remaining - are limited to flowering. As a result of the evaluation of decorative irises studied received 90 or more points. The highest decorative qualities are characterized by varieties Clash and Well Suited, scored 98 points. On the basis of the assessment it was found that the studied varieties are adapted for cultivation in the forest-steppe zone of the Bashkir Ural.
