Red Currant

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’.

In the production of planting material, it is important to choose a healthy, highly productive source material, with typical varietal characteristics, and, if necessary, their disinfection), as well as reliable protection against dangerous pests at further stages of cultivation. This requires a scientifically based methodological approach and phytosanitary measures in several areas. First of all, it is required to study and classify in detail hazardous pests and pathogens, select methods for accounting and identifying in accordance with their degree of danger and the quality category of planting material. Apply comprehensive measures to prevent the entry of pests in the territory of growing planting material and timely eliminate the centers of potential threat.

Crop System

Parasitoids are currently considered for biological control of the spotted wing drosophila (SWD) in berry crops. Releases of mass-reared parasitoids require the presence of all resources necessary to ensure their effectiveness in the crop system. The use of floral resources to feed Trichopria drosophilae, one of the candidate species, was investigated in a laboratory study. The life expectancy of males and females increased by three to four times when they had access to flowers of buckwheat or of two cultivars of sweet alyssum. Female realized lifetime fecundity increased from 27 offspring/female exposed to water only to 69 offspring/female exposed to buckwheat flowers. According to this almost threefold increase in parasitoid fitness, it is advisable to introduce flowering plants into the crop system, when parasitoid releases are carried out. Sweet alyssum offers the advantage of not growing too tall in combination with an extended blooming. However, adult SWD were also able to feed on flowers of both plants and survived for at least 27 days, much longer than starving flies. The introduction of flowering plants to promote natural enemies therefore requires further consideration of the risk–benefit balance under field conditions to prevent unintended reinforcement of this pest.

Debnath, S. C., Siow, Y. L., Petkau, J., An, D. and Bykova, N. V. 2012. Molecular markers and antioxidant activity in berry crops: Genetic diversity analysis. Can. J. Plant Sci. 92: 1121–1133. An improved understanding of important roles of dietary fruits in maintaining human health has led to a dramatic increase of global berry crop production. Berry fruits contain relatively high levels of vitamin C, cellulose and pectin, and produce anthocyanins, which have important therapeutic values, including antitumor, antiulcer, antioxidant and anti-inflammatory activities. There is a need to develop reliable methods to identify berry germplasm and assess genetic diversity/relatedness for dietary properties in berry genotypes for practical breeding purposes through genotype selection in a breeding program for cultivar development, and proprietary-rights protection. The introduction of molecular biology techniques, such as DNA-based markers, allows direct comparison of different genetic materials independent of environmental influences. Significant progress has been made in diversity analysis of wild cranberry, lowbush blueberry, lingonberry and cloudberry germplasm, and in strawberry and raspberry cultivars and advanced breeding lines developed in Canada. Inter simple sequence repeat (ISSR) markers detected an adequate degree of polymorphism to differentiate among berry genotypes, making this technology valuable for cultivar identification and for the more efficient choice of parents in the current berry improvement programs. Although multiple factors affect antioxidant activity, a wide range of genetic diversity has been reported in wild and cultivated berry crops. Diversity analysis based on molecular markers did not agree with those from antioxidant activity. The paper also discusses the issues that still need to be addressed to utilize the full potential of molecular techniques including expressed sequence tag-polymerase chain reaction (EST-PCR) analysis to develop improved environment-friendly berry cultivars suited to the changing needs of growers and consumers.

A comprehensive study comparing virus detection between high throughput sequencing (HTS) and standard protocols in 30 berry selections (12 Fragaria, 10 Vaccinium and 8 Rubus) with known virus profiles was completed. The study examined temporal detection of viruses at four sampling times encompassing two growing seasons. Within the standard protocols, RT-PCR proved better than biological indexing. Detection of known viruses by HTS and RT-PCR nearly mirrored each other. HTS provided superior detection compared to RT-PCR on a wide spectrum of virus variants and discovery of novel viruses. More importantly, in most cases where the two protocols showed parallel virus detection, 11 viruses in 16 berry selections were not consistently detected by both methods at all sampling points. Based on these data we propose a four sampling times/two-year testing requirement for berry and potentially other crops to ensure that no virus remains undetected independent of titer, distribution or other virus/virus or virus/host interactions.

The paper defines the structural distribution of sown area of crops. The dynamics of production of cereals and legumes, sugar beets, sunflowers, potatoes, vegetables, fruits and berries. The clustering of regions of Ukraine under similar conditions of development of the enterprises of the agricultural sector specializing in crop production is carried out. According to the results of the analysis, 3 clusters were identified, which gave rise to the possibility of forming (developing) joint effective organizational and economic mechanisms to enhance the development of crop enterprises, favorable for implementation within the cluster. In the course of this study, we focus on the development trends of enterprises specializing in crop products. The lion's share (54.7 %) of sown areas falls on cereals and legumes. Technical crops occupy, which is 32.6 %, and potatoes, vegetables and melons – 6.5 %. It is important to note the long-term positive dynamics of production of cereals and legumes and the growth of production can be traced to all categories of farms – in farms and households. The production of sunflower and vegetable crops was also marked by positive dynamics. The decrease was observed in the production of sugar beets, potatoes, fruit and berry crops. In the context of the study, it is important to identify similar conditions (environment, resources, etc.) for the development of agricultural enterprises between the regions of Ukraine. For this purpose, multifactor statistical analysis (cluster analysis) of key factors of their development was used on the basis of a matrix of 25 selected indicators of development of enterprises specializing in crop production in all regions (600 indicators). To enhance the objectivity of the results, the analysis was conducted in 2010, 2015 and 2019. According to the results of the analysis, taxonomic groups (clusters) were singled out, which made it possible to single out similar regional conditions within each group. Since 2010, there have been significant changes in the regional distribution of Ukraine's agricultural potential. However, during 2015–2019 there is a relative stability in terms of resource provision and use within specific clusters. According to the results of the analysis, three clusters are distinguished: I. Volyn, Zakarpattia, Ivano-Frankivsk, Lviv, Rivne, Chernivtsi, as well as Donetsk and Luhansk regions. II. Dnipropetrovsk, Zhytomyr, Zaporizhia, Kyiv, Mykolaiv, Odesa, Ternopil, Kharkiv, Kherson, Khmelnytsky regions. III. Vinnytsia, Kirovohrad, Poltava, Sumy, Cherkasy and Chernihiv regions.

Genetic resources of temperate berry crops were collected 7 to 27 July 2004 in Hokkaido, Japan, under a bilateral agreement between the United States and Japan. This expedition was a collaborative effort between the United States Department of Agriculture (USDA), the Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF), the University of New Hampshire, and Akita Prefectural College of Agriculture, Japan. Additional assistance was provided by the Hokkaido Governmental Plant Genetic Resources Center, several Forest Research Stations of the Hokkaido University, and private botanists. The expedition obtained 100 accessions encompassing eight genera and 29 species. In all, 84 seedlots, and 23 plants were obtained. The genera collected included: Actinidia, Fragaria, Lonicera, Morus, Ribes, Rubus, Sambucus, and Vaccinium. Plant and seed accessions from this trip are preserved and distributed from the USDA ARS National Clonal Germplasm Repository in Corvallis, Ore., and from MAFF. The target genus for this expedition was Fragaria, so the trip was planned for July. Multiple samples of the two Japanese diploid strawberry species, Fragaria iinumae Makino and F. nipponica Makino (synonym = F. yezoensis H. Hara) were obtained during their prime ripening time. Ribes, Rubus, and Vaccinium fruits ripened later in the summer, but were collected when fruit were observed. Unfortunately, seeds of some of these accessions proved to be immature or nonviable upon extraction. We suggest that expeditions to collect these genera should be planned for late August. Morphological and molecular evaluation of collected germplasm is underway at the USDA ARS Corvallis Repository and at the University of New Hampshire.

Results. Provides information on new economically important species Halyomorpha halys Stål., which is rapidly spreading in Europe. In Ukraine, the marble bug has the status of a quarantine, but there is a risk of further spread. His first appearance on the territory of our country has registered in 2018 Threat of invasive species, a polyphage, which causes significant damage to agricultural, forest and decorative cultures. Pest can cause damage to fruit, berry crops, vineyards, beans, soy, corn, and weeds. The list of host plants includes over 300 species of plants from 49 families, however, the preference for Halyomorpha halys gives the members of the family Rosacea. Danger of falling of the pest in Ukraine of the European countries of planting material, plant products, wood packaging materials, Luggage etc. The absence of natural enemies promotes the active dispersal of the pest. The focus should be directed on the study of natural brown marble bug. The rapid spread of Halyomorpha halys in the EU countries is of great concern to scientists. The experience of foreign scientists shows that effectively regulates its abundance parasitoid Trissolcus japonicas (Ashmead) and entomoparasitic fungus Beauveria bassiana. Conclusions. There is an active resettlement of the pest in Europe. There is a risk of introduction and spread of the species Halyomorpha halys Stål, is a threat to the country.
