RESULTS OF BREEDING AT THE NULESU, UKRAINE

Volodymyr MEZHENSKYJ, Dr. Sc., prof. V.L. Symyrenko Horticulture Department, National University of Life and Environmental Sciences of Ukraine Ribes L.

The genus Ribes L. (Grossulariaceae) includes some edible gooseberries and currants which are among popular small crops in Ukraine. Fruit currants are divided into Pursh Ribes nigrum L. (R. nigrum L.), red and whitecurrant (Ribes petreum Wulfen, R. rubrum L., R. spicatum E.Robson and their interspecies hybrids) and goldencurrant (5). Most gooseberry belong to hybrids between European R. uva-crispa L. and some American species.

Ribes rubrum L. Ribes uva-crispa L. Currants and gooseberries in Ukraine

The both gooseberry and currant cultivars are widely grown in commercial and amateur SmalI orchards in Ukraine. The area of currant plantations at bearing age makes 4.5 thousand hectares and the area of the gooseberry plantations makes 0.9 thousand hectares, which are 22.7% and 4.5% of total area, respectively. Ukrainian currant production estimated annually is estimated roughly at 24,5 thousand tons, and gooseberry production is estimated at 6.6 thousand tons. The State Register of Varieties Suitable for Dissemination in Ukraine in 2020 includes 26 black currant cultivars, 11 red and cultivars, and 21 gooseberry cultivars. Petro Sherenhovyj (1924-2016)

The breeding work on Ribes was started at the NULESU (former Ukrainian Agricultural Academy) in 1984. Petro Sherengovyi, as the founder of the breeding program, used methods of cross breeding, either via controlled crosses or via open pollination and as well as bud sports. Initial material was the varieties of small fruit crop early collected by Sherenhovyi which was included a lot of berries, including 98 blackcurrant cultivars. Selections were made in large number of seedlings based initially on subjective evaluation of fruit quality, yield, and plant health. The final selections were used for the observation and replicated plots. Most promising selections were tested according to guidelines for distinctness, uniformity, and stability tests and registered in Ukraine as new cultivars. Origin of currant cultivars

18 new black current, white current, red current, and gooseberry cultivars developed at the NULESU were included to the State Register of Plant Varieties of Ukraine in 1999–2016. They are resistant to main diseases, have high fruit quality, suitability for fresh market and processing, and good adaptability to condition of the northern part of Ukraine. Thank you for attention
