Abstract

New cultivar of mountain ash (Sorbus) Siberian breeding.

Abstract

The northern regions of Russia are characterized by a relatively poor composition of the cultural dendroflora, that due to harsh climatic conditions. To create resistant varieties, it is necessary to attract local highly winter-resistant forms and on their basis to obtain hybrids with foreign species with outstanding characteristics of economically useful traits. As a result of hybridization of the breeding form of S. sibirica with a undersized and large-fruited breeding form of S. sambucifolia was obtained the heterosic hybrid 'Shank' (F1S. sambucifolia x S. sibirica) that combining valuable decorative and nutritional qualities, with ultra-fast of fruiting start and highly winter-resistant.
