In 2015, the Council of Plants Genetic Resources agreed to include genus Hemerocallis (daylily) and genus Paeonia (peony) into the collections of genetic resources of the National Program. In addition to the selection of plants suitable for the National Program, we started to prepare descriptor lists for these genera in cooperation with students of the Department of Horticulture Faculty of Agrobiology, Food and Natural Resources Czech University of Life Science, Prague. The descriptor list was supposed to cover botanical characteristics of wild species as well as the advanced garden ornamental varieties, because the species of peonies and daylilieas are medicinal plants and it is therefore appropriate to incorporate them in the National Program. At the same time, it turned out that the descriptor list used for Iris is intended primarily for bearded irises (Iris subgen. Iris). However, in the last twenty years, the Czech breeders have specialized also in other groups of irises, especially in Siberian and Japanese irises and Spuria group, which don’t have any beard on outer tepals and have other differerent characteristics from the subgenus Iris. Therefore, we have decided to extend the existing descriptor list to cover the whole genus except bulb irises.

Designing of new classifiers for peony, daylilies and non-bearded irises in the Průhonice botanic garden.

With accepting new genera (Hemerocallis, Paeonia, Iris subgen. Limniris) into National Program for Genetic Resources, a need for creating new classifiers for cultivar description has risen. When proposing classification characteristics, we have resulted from botanical monographies of the genera, existing classifiers and from experience in cultivar description. In creating and evaluation of the classifier we have cooperated with leading institution, Gene Bank of Crop Research Institute, and Department of Horticulture (FAFNR) at Czech University of Life Sciences, which has submitted it as a diploma and a bachelor thesis. New classifiers will be published in 2019 in GRIN Czech database.
