The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

As a result of the studies, we found that the bulk of the studied black currant varieties are more or less susceptible to columnar rust. Both derivatives of the European, Siberian subspecies and dikusha currant and species obtained with usage Scandinavian subspecies are characterized by high sensibility to this disease. In the European zone the most widespread and harmful are the fungal diseases of black currant - septoriosis, anthracnose, powdery mildew. Substantial damage to this culture plantations is caused by epiphytoty which repeated every three to four years. In contrast to American mildew, columnar rust intensely affects plants during the mass ripening of berries, which makes it difficult to carry out protective measures. The most effective method for solving this problem was the remote hybridization which is participation of wild species with the necessary characteristics, but their involvement leads to deceleration of the selection process, as apart from the necessary characteristics they have those that reduce the value of hybrid progeny, and it takes several hybrid generations to achieve the necessary results. In the Institute on the base on disjoining of hybrid progeny was established the oligogenic nature of the inheritance of resistance to columnar rust in currant derivatives. It was revealed that it confers immunity to columnar rust in addition combines immunity with American powdery mildew. As a result, the Re gene was identified, as well as Kipian and Gamma varieties, which are actively used as immunity donors. Assessment of varieties for resistance to diseases and pests was carried out in the areas of primary variety testing according to the methodology for the study of fruit, berry and nut-bearing crops.

 Resistance to diseases and pests is one of the main tasks of a breeder when creating varieties of cultivated plants. On perennial plants, which include black currants, diseases have a significant impact on the quantity and quality of the formed yield, as well as on the laying of the subsequent yield. Constant screening of new breeding material allows not only to select and isolate promising highly resistant forms at the early stages of ontogenesis, but also, as a result, to speed up the entire selection process of creating immune varieties. As a result of our research, we found that the bulk of the studied hybrid seedlings in 2019-2020 were resistant to American powdery mildew and columnar rust. High resistance to American powdery mildew is characteristic of derivatives of glutinous currant and the Scandinavian subspecies of black currant. Also, the derivatives of glutinous currant are characterized by high resistance to columnar rust.

Elite varieties of black currant selected at the Federal Agrarian Scientific Centre of the North-East were studied with the purpose of identifying samples with an optimal combination of high productivity, large fruit, good taste, resistance to big bud mite and powdery mildew. The studies were carried out in 2015–2019 on a site located in the central agro-climatic zone of the Kirov region. 10 elite black currant varieties of 2013 planting were investigated. The varieties of Arkadiya and Vologda were used as control. The counts and observations were carried out using conventional methods. The combination of high productivity, its sustainability and high self-fertility was noted in varieties 71-2-07, 65-1-07 and 64-4-07. In terms of resistance to the pest, two highly resistant samples 71-2-07 and 65-1-07 were identified, which showed no signs of damage during the study period. The damage by big bud mite remained low across the entire experimental site. The average negative effect of big bud mite on the yield was found (r = -0.48). In the following 7 elite forms — 71-2-07, 65-1-07, 70-5-07, 46-1-07, 12-1-07, 15-1-07, 20-1-07 (70.0 % of the studied material), the maximum degree of damage by powdery mildew did not exceed 1.0 points, which indicates their high resistance. The combination of high resistance to big bud mites and resistance to powdery mildew was found in varieties 71-2-07 and 65-1-07. During the study period, 9 elite black currant varieties produced large-fruited berries. Out of these 9 forms, 3 (71-2-07, 64-4-07, 12-1-07) showed significantly higher values of this indicator compared to the Vologda control. Sample 27-1-07 was distinguished by a combination of large fruit, good taste and low acidity, as well as by high contents of ascorbic acid and dry matter. Sources of economically valuable traits were identified in 2 samples: 65-1-07 having a combination of high productivity, large fruit, high self-fertility, good taste, resistance to big bud mites and powdery mildew; 64-4-07 having a combination of high productivity, large fruit and high self-fertility. These genotypes can be recommended as a starting material for further breeding. On the basis of the results obtained, the Ariel variety (71-2-07) was forwarded to the State Variety Testing in 2020.

Important Disease

Powdery mildew, caused by Podosphaera xanthii, is an important disease of melon in the Brazilian Northeast. The objective of this work was to evaluate the reaction of families, lines and cultivars of melon to P. xanthii. Two experiments in simple lattice were carried out under field conditions in the municipalities of Mossoró and Baraúna to evaluate 144 families. In a greenhouse, an experiment was carried out in a completely randomized design to evaluate 19 lines and the cultivars Yellow Queen, Chilton and Hy Mark. Disease was assessed by a severity scale. There was genetic variability among families. The families 4, 5, 11, 14, 18, 23, 33, 42, 101, 112 and 140 were identified in both sites as resistant. The lines LOF-027, LOF-105, LPS-124, MEL-008 and cultivar Chilton showed resistance to race 1 of the fungus.
