Abstract
Long-term researches showed that representatives of cultivars of Saintpaulia H. Wendl. are most long flowering plants of family of Gesneriaceae Dumort. in the protected soil of Oles Gonchar Dnepr National University Botanic Garden. The decorativeness of cultivars was determined on morphometric and biological descriptions: to correlation to the diameter of flower with a width and long sheet plate, to the form of flower, double, fringed of edge of petal, and also general proportion of corolla, the phenology of flowering and other. Descriptions of the most perspective cultivars of Saintpaulia getting top marks on the scale of estimation are considered. A brightness, chromaticity, maintenance of these qualities during all life of flower (more than 2 months at some cultivars), beauty and harmoniousness of picture at multicoloured Saintpaulia, was taken into account. Studies and observations were conducted in the stock conservatory of the laboratory of tropical and subtropical plants from 1997 to 2018.We used garden classification of The Special Comity of The African Violet Society of America – AVSA, scale of assessment of economic-biological and decorative features. A complex evaluation of 60 cultivars from the genus Saintpaulia from the laboratory of tropical and subtropical plants of the botanical garden of the DNU was carried out.
 It is educed, that most showily plants look with flowers, having a size of corolla, equal to the width of sheet plate, or less than her no more, than on one centimeter. Most objects driven to this article respond to this request and have the highest productivity of flowering. The evaluation of ornamental properties and prognosis of the succesful introduction of 20 taxsons (the sorts: EK-Boy Bykov, ЕК-Belaya Koroleva, EK-Zhemchujniy Zephyr, Arctic Frost, Blue Dragon, Kilauea et al) have been given. Perspective for cultivation in closed soil species have been selected. Modern varieties for indoors greenbelt setting have been listed.
 The got results served in future for creation of scale of cultivars of Saintpaulia and complex estimation of their decorativeness. All studied cultivars are used in an educational process.

Summary
MORPHOMETRICAL AND BIOLOGICAL INDICATORS IN DEFINITION DECORATIVE REPRESENTATIVES TO THE. A complex evaluation of 60 cultivars from the genus Saintpaulia from the laboratory of tropical and subtropical plants of the botanical garden of the DNU was carried out. It is educed, that most showily plants look with flowers, having a size of corolla, equal to the width of sheet plate, or less than her no more, than on one centimeter. Основные биоморфологические и морфометрические признаки представлены в табл. , в которых отражены результаты исследований 20 наиболее перспективных сортов, отобранных из общей массы при комплексной оценке [4]. Также для изучения биоморфологических особенностей генеративной части сортов рода Saintpaulia мы добавили признаки «количество одновременно раскрытых цветков на цветоносе (кцц)», «количество цветоносов на розетке», «продуктивность цветения»
