Currant Gall Mite Research Articles

Creation of new initial forms of black currant (Ribes nigrum L.) in breeding for adaptation

The article presents the results of studying the black currant varieties collection of the Kokinsky control station of the FSBSI FRC for Horticulture (Bryansk region) for winter hardiness, resistance to Sphaerotheca, and currant gall mite in order to create new initial forms based on the selected genotypes, characterized by a high level of adaptation for their inclusion in the breeding work to improve the crop assortment. The best combinations of crosses (Gamayun × Nara, 33-27-1 × Kipiana, 33-27-1 × Bryanskiy Agat, Favorit × Dar Smolyaninovoy, etc.), the initial forms for inbreeding and free pollination, in the progeny of which the largest number of winter-hardy seedlings, characterized by resistance to Sphaerotheca and gall mite, were identified. Promising winter-hardy Sphaerotheca-resistant forms were identified 4-63-4, 72-03-7, 3-37-26/02, 62-03-7, 1-5-1, 63-35-1, 3-134-01, 28-03-1, 5-82-02, 1-91-01, immune to gall mite.

On some Species of Gall-mites (Eriophyidae) found on Corylus avellana, L.

The nut gall-mite (Eriophyes avellanae, Nal.) is one of the commonest species of gall-mites that occurs in this country, and it may be found infesting the buds of hazel (Corylus avellana) in almost any hedgerow and copse where this plant grows. The species is found also in America and in Continental Europe. Its life-cycle is very similar to that of the black currant gall-mite, E. ribis (Westw.) Nal.
