Abstract
Aim. The creation of adapted cultivars of black currant with high (15 - 17 t/ha) stable yields, large fruited (average fruit mass 2g or more), content of vitamin C in fruits 200 mg/100g or more, sugars 10%, simultaneous maturation, dry separation and durable skin of berries, 80% self-fertility, suitability for mechanized harvesting. Methods. The selection work was carried out taking into account the main provisions of the «Program and Methods of Breeding of Fruit, Berry and Nut- Bearing Crops». The requirements of the «Program and Methods of Breeding of Fruit, Berry and Nut-Bearing Crops» have been taken into account during the cultivars study. Results. The created cultivar collection allowed identifying the most perspective cultivars for cultivation in the local conditions, and genetic sources for further breeding. As a result of breeding researches, 12 cultivars of black currant have been created, 7 of which are included in the State Register of Breeding Achievements admitted to be used. Main conclusions . By the present time, a large and substantial work on the breeding of black currant has been carried out and effectively continues on the Kokino Base Station of FSBSI of the All-Russia STIHN. Genetic sources of the main economic and valuable signs are allocated: - high hardiness: variety Dar Smolyaninovoy, Lentjy, Litvinovskaya, Pamyati Ravkina, Partisanka bryanskya, Selechenskaya 2, Tamerlan, Gamayun, Favorit, Tharodey, Kudesnik, Podarok Veteranam, selections 4-18-12, 5-66-5, 33-27-1, 8-03-15, 8-2-97, 8-4-5, 18-18-6/05 et al.; - resistance to powdery mildew, leaf spots and bud mite: varieties Gratsiya, Kipiana, Tamerlan, Nara, Litvinovskaya, Spharovidnaya, Kudesnik, Podarok Veteranam, Strelets, Chudnoe mgnovenie, selections 2-7-1/08, 4-34-8, 5-4-2/08, 33-27-1, 33-27-7, 36-14-1, 36-17-8, 44-8-1, 63-35-1 et al.; - large fruits: varieties Bryansky agat, Debryansk, Mif, Kudesnik, Istok, selections 5-03-8, 5-66-5, 6-14-3, 6-14-4, 37-27-4/05, 21-12-1, 68-03-1, 11-6/05; - high density of berries: varieties Tamerlan, Sudarushka, Partisanka bryanskya, Myf, Tharodey, Kudesnik, Vera, selections 5-66-5, 8-2-97, 8-4-5, 9-3-97, 18-18-6/05, 33-27-1, 68-03-1, 73-03-2 et al.; - increase the level of accumulation of vitamin C (> 200 mg/100 g): varieties Sudarushka, Barmaley, Istok, Bryansky agat, Kudesnik, Podarok Veteranam, selections 8-2-97, 8-4-5, 33-27-1, 45-55-1, 33-14-3 et al.
