Abstract. The results of the state testing of red currant varieties in the Prokopievsky Fruit-Berry State Station of Variety Testing (West-Siberian region) in 2015–2017 are presented. The task of the research was to test the Russian Research Institute of Fruit Crop Breeding red currant varieties in the soil-climatic conditions of the West-Siberian region. Methods. 13 varieties from the All-Russian Research Institute of Fruit Crop Breeding (Orel region), 5 varieties from the Novosibirsk Zonal Fruit-Berry Experimental Station (Novosibirsk region) and 3 varieties from the South-Urals Research Institute of Fruit and Potato Growing (Chelyabinsk) were studied. The red currant variety “Red Cross” in the West-Siberian region was taken as a standard. The observations and records were carried out according to the Methods of the state variety testing of agricultural crops. Results. For three year of the study, on the average, the productivity of the standard was 63.3 centner per hectare. The varieties from the former Novosibirsk Zonal Fruit-Berry Experimental Station “Valensiya”, “Khrustyashchaya” and “Eliza” were on the same level of productivity with the standard, while “Rozita” was inferior to the standard. The varieties from the South-Urals Research Institute of Fruit and Potato Growing significantly exceeded the standard in terms of the crop load: “Ilyinka”, “Ural’skaya krasnaya” and “Ural’skaya belaya” (93.3–84.4 centner/ha). The varieties from the All-Russian Research Institute of Fruit Crop Breeding had higher rate of productivity: 122.5 centner/ha (“Marmeladnitza” – 102.6 centner/ha (white-fruit variety “Belka”). “Gollandskaya krasnaya”, “Khrustyashchaya”, “Belka”, “Uralskaya belaya” and “Roza” are characterized by a dessert taste (5.0 point). In conditions of the Kemerovo region the varieties “Asya”, “Dar Orla”, “Dana”, “Ilyinka”, “Marmeladnitza”, “Orlovchanka”, “Podarok leta”, “Ural’skaya krasavitsa”, “Niva” and “Belka” are characterized by large size of fruit with maximal berry weight of 0.9–1.3 g. “Ilyinka”, “Marmeladnitsa”, “Ural’skaya krasnaya”, “Belka” and “Ural’skaya belaya” demonstrated a complex resistance the main diseases of red currants- anthracnose and septoria. Scientific novelty and practical importance. The results of the introduction showed that the All-Russian Research Institute of Fruit Crop Breeding red currant varieties have high environmental adaptability to the conditions of the sharply continental climate. As a result of the testing, the varieties “Asya”, “Dana”, “Marmeladnitsa”, “Orlovchanka”, “Dar Orla” and “Podarok leta” (Orel breeding) are included in the State Register of breeding achievements admitted for use in the West-Siberian region.
