Forming of domestic blackcurrant stock in Non-Chernozem Region of Russia

Abstract

Research was conducted with the blackcurrant genetic stock collection at the Kokino base station of Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Bryansk Region) during 2014-2020. We studied 110 varieties and 30 selected forms isolated in different years for main marketability criteria. Te study aimed at the selection and creation of cultivars and forms of blackcurrant with economical and breeding advantages to optimise the zoned stock with domestic varieties for industrial and home gardening in the south-west Non-Chernozem Region of Russia and promote further breeding effort. Source material processing and breeding work were carried out using the generally accepted protocols. Cultivars and promising forms with the good winter hardiness, resistance to Sphaerotheca powdery mildew, strength, uniform size and taste of berries have been selected. Of interest are the cultivars producing an average fruit mass >=2.0 g under optimal weather and agrotechnical conditions: Litvinovskaya, Dar Smolyaninovoy, Podarok Astakhova, Yadryonaya, Kudmig, Bryanskiy Agat, Debryansk, Mif, Kudesnik, Istok, Nos. 68-03-1, 36-27-4/05, 5-66-5, 5-03-8. Te best-yield (up to 12.5 t/ha) cultivars identified were: Barmaley, Bryanskiy Agat, Debryansk, Mif, Favorit, Dar Smolyaninovoy, Litvinovskaya, Selechenskaya-2, Kudmig, Tamerlan, Shalunya, Ladushka, Lentiay, Iskushenie, Kipiana, Orlovskiy Valz, selections 68-03-1, 36-27-4/05, 5-66-5 and others.
