INTERSPECIFIC CROSSING IN GOOSEBERRY BREEDING AS THE BASIS FOR THE INDUSTRIAL-TYPE VARIETIES CREATION

Abstract

For optimal cultivation of gooseberries, the presence of industrial-type cultivars plays an important role, therefore, the study of economically useful parameters, such as resistance to diseases and pests, productivity, high commercial qualities of berries, suitability for combine harvesting is relevant. Consequently, the goal of the present research was to study remote gooseberry hybrids obtained on the genetic basis of a mighty gooseberry species (Grossularia robusta) involved in hybridization according to the main economic and biological characteristics. Selected gooseberry forms obtained from the remote (interspecific) hybridization with Grossularia robusta species were the studied material. The degree of damage by the American powdery mildew, the quality of berries and suitability for machine harvesting were assessed. As a result of the long–term study of hybrid offspring obtained from interspecific crosses, promising selected forms F₂ 9-283-1(2) and F₂ 9-283-1(6) (seedlings from the open pollination from the family 142-x36-12 ? Grossularia robusta) have been identified, which are of interest for further practical breeding of gooseberries when creating commercial cultivars of industrial type.
