Abstract: 

The article presents the results of studying the fruiting in 9 clematis cultivars under the conditions of the southern coast of Crimea. Morphometric characteristics of seeds, their weight and germination capacity are given. Potential and real seed production was assessed. It was found that the studied cultivars are characterized with high potential seed production, on average from 38.1 to 116.9 ovules per fruit, but relatively low real seed production, on average from 1.3 to 8.3 seeds per fruit. Among the studied cultivars, the largest number of viable seeds formed per plant was noted in 4 cultivars: ‘Jan Pawel II’, ‘Ramona’, ‘Elegia’ and ‘Juulii’. These cultivars are recommended for use in breeding works as maternal parental forms
