A gooseberry (Ribes uva-crispa) hybrid fund in the quantity of 665 plants received from 23 combinations of the convergent crossings of the American and European cultivars and hybrids was studied in the conditions of the Republic of Belarus. There were analyzed five groups of hybrids of a various specific origin on the resistance to the American powdery mildew (pathogen Sphaeroteca mors-uvae (Schw.) Berk et Curt.). Inclusion in hybridization of cultivars and hybrids of two derivative kinds Grossularia succirubra and Gr. reclinata, and also a combination in hybrid descendants of a genetic material of three species Gr. robusta, Gr. succirubra, Gr. reclinata and Gr. robusta, Gr. hirtella,Gr. reclinata promotes hybrids receiving differed by high resistance to spherotech of vegetative and generative plants organs. The basic inheritance type of spherotech resistance of vegetative organs in hybrid gooseberry descendants is a positive domination of resistance. There have been also marked a negative domination and intermediate inheritance. The type of a resistance inheritance of generative organs varied from depression to positive overdominance with prevalence of positive domination.
