The introduction of dwarf bearded irises in South-Ural Botanical Garden-Iinstitute

The article presents the results of the study of introduced varieties of dwarf bearded irises (Filippok, Deep Lavender, Bright White,CherryGarden, Clash, Well Suited, Banbury Ruffl es, 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 varieties 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 evaluation of ornamental features was carried out according to the generally accepted methodology, and also used the scale of comparative variety evaluation developed by theMainBotanical garden. As a result of the phenological observations there was revealed that the timing of fl owering all studied irises, except for the variety Skip Stitch, attributed to the early flowering – the beginning of fl owering is observed in May. The earliest onset of the fl owering phase was observed in the variety April Accent (May 21); at the latest – in the variety Skip Stitch (June 03). The duration of the fl owering phase ranged from 10 (Inscription) to 27 (Lace Caper) days. The life of the fl ower 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 varieties are limited to fl owering. As result of the conducted evaluation of ornamentality, the studied irises received 90 or more points. The Clash and Well Suited varieties were characterized by highest ornamental qualities, which scored 98 points. On the basis of the conducted evaluation it was found that the studied varieties are adapted for cultivation in the forest-steppe zone of the Bashkir Ural.
