“…In 2019, as a result of testing the "Joonas-2000" berry harvester (Finland) (Figure 5) on the studied red currant cultivars, it was found that the previously studied limiting and non-limiting signs were fully confirmed in practice. The conclusions made are confirmed in the reports of Dale et al (1994), Gurin (2000), Yakimenko (2001), Barney, Hummer (2005), Danshina (2017), Sazonov (2018), Kanarskiy, Makarychev (2019).…”

“…In this experiment, the biological (morphological) features of the structure of the bush (height, width, volume, compactness) were quite stable due to a small range of phenotypic variability, which was confirmed by the relatively low values of the coefficient of variation (CV). The biometric values of the bushes' growth habit are mostly determined by the genetic characteristics of the cultivar and are not subject to changes in the environmental conditions (Sazonov, Danshina 2016;Sazonov 2018).…”

The physical and mechanical parameters of berries and the morphometric features of the structure of the bush growth habit are important criteria in predicting the use of berry harvesting equipment. In this research, six red currant cultivars have been studied. The berry separation force, the crushing force, and the strength of attachment of the berries to the stalk were assigned to the physical and mechanical parameters and were determined using the "PLODTEST-1" and "Dina-2" devices (Russia). For the optimal operation of the berry harvester, the crushing force of the berries must be more than 2 N, the berry separation force must be in the range of 0.5–1.5 N. A high correlation between the separation and crushing forces was determined (R = 0.71). During the period of technical maturity, the strength of the attachment of the berries in the raceme was more than 0.5 N and, by the end of maturation, this indicator decreased. Most of the studied cultivars have a compact, optimal bush volume. The red currant cultivars Niva, Asya and Vika are promising for mechanised harvesting.

“…A little portion of small fruit plantations in huge specialized households is mostly connected with high labor intensity of hand harvesting which takes up to 70 % of all expenses (Sazonov, 2006;Kazakov et al, 2009). Depending on the crop, variety or yield this operation requires 200-300 man work units/ha, which is 3-5 times higher than is necessary for fruit crop harvesting.…”

It is possible to achieve the target indices of the Russian Doctrine of Food Security (self-sufficiency in fruits and berries should be at least 60 %) by combining the competencies of science and business. At present, hundreds of varieties of small fruit crops are included in the State Register of Breeding Achievements Admitted for Use. Domestic breeders have obtained substantial results; the share of their assortment is 79–100 %. Federal Research Center of Horticulture (Moscow) (101 pcs.), Federal Altai Research Center of Agrobiotechnology (Barnaul) (85 pcs.), Michurin Federal Research Center (Michurinsk) (42 pcs.) are the leaders in the number of created hybrids and varieties. Over the past five years, 133 new breeding achievements of traditional small fruit crops have been submitted to the State variety testing, the originators of which are research institutions, private companies and individuals. The creation of modern seed-breeding (nursery-breeding) centers (SBC) on the basis of leading specialized research institutions is expected to be the solution to the problems of modern breeding and nursery breeding and to give impetus to the development of domestic small fruit growing. The research programs of the SBC involve an integrated approach that combines the knowledge and capabilities of researchers from different disciplines, the concentration of a complex analytical instrument base in the Centers of collective use, the using of biotechnological and molecular genetic research, along with traditional methods of breeding. An analysis of the achievements in small fruit growing in research institutions under the jurisdiction of the Ministry of Science and Higher Education of the Russian Federation revealed a huge scientific potential (genetic collections, hybrid funds) for creating competitive commercial varieties and technologies for their cultivation by establishing plantations with certified planting material in accordance with international requirements. Information from literary sources indicates that one of the main criteria for the value of varieties is resistance to harmful viral diseases. The cultivation of such varieties will reduce the cost of producing planting material for small fruit crops of the highest quality categories. In the near future, the most relevant areas for the breeding of small fruit crops will be: breeding for resistance to the most harmful viruses, winter hardiness, increased transportability and long-term post-harvest storage of fruits, suitability for mechanized cultivation, high content of biologically active substances.

“…An approximate model of the mechanical parameters of black currant berries has been developed to use a mechanized harvester with minimal losses possible with a force of 0.5-1.5 Newton (N) for separation of berries in the cluster and a can rushing force of at least 2.0 N. The physical and mechanical properties of berries can indicate the period of removable maturity, and the commercial qualities of berries will meet the standard criteria [14,22]. However, the most significant disadvantages of black currant cultivars identified during machine harvesting are significant loss of leaves and fragility of branches, causing a reduction in the productive period by about 2-3 years and decreasing the efficiency of harvesters [23][24][25][26][27][28][29][30]. The main parameters such a cultivar should correspond to are distinguished in breeding programs for current technological cultivars.…”

The cultivation of berry crops by the type of "intensive plantings" is an economic and scientific approach in modern horticulture. The principles of forming a red currant assortment adapted to mechanized harvesting are considered. The bush should be compact for mechanized harvesting and have a straight-growing or slightly spreading shape. The morphological structure of the bush is a feature determined by the genotype. The ripening period of berries and the mechanical parameters of berries assess the effectiveness of the berry harvesting process. With the help of agrotechnical techniques, the mechanical parameters of berries cannot be improved and are de-termined by weather, soil, water, and climatic factors. The present study was conducted in the 2021-2022 season using 14 red currant genotypes of different geographical and genetic origins to assess cultivars' suitability for machine harvesting. In most of the studied cultivars, berry quality indicators, the parameters of separation force (Fs) and crushing force (Fc) decreased by the time of biological maturity of the genotype. Several cultivars have shown a non-simultaneous decrease in Fs and Fc. A minor limiting feature determines the duration of harvesting. The high correlation of Fs and Fc (R=0.75-0.85) allows us to predict the most significant period for the high-quality operation of a mechanized harvester. There was no dependence of the strength of the attachment of berries to the peduncle on the thickness of the skin of the berries. Jonkheer Van Tets, Red Lake, Rovada, Rolan, Vika, Asya, and Niva can be attributed to technological cultivars as sources of compact and erect bush habit, Jonkheer Van Tets, Rovada, Rolan, Vika, and Asya are recommended for mechanized harvesting.
