Fertility of pollen grains is their ability to induce full fertilization. This parameter is one of the most important in the selection of pairs when crossing all fruit crops, including sour cherry. The determination of this parameter in selected and elite forms of sour cherry is an urgent direction in breeding. The purpose of these studies was to determine the fertility of pollen in four selected and elite forms of sour cherry breeding in the Russian Research Institute of Fruit Crops Breeding (RRIFCB). The studies were conducted at the laboratory of cytoembryology over 2 years, from 2019 to 2020, and their results are preliminary. As objects of research, 4 selected and elite forms of sour cherry, with high taste and marketability, were taken. The sour cherry variety Turgenevka, obtained at RRIFCB, was chosen as a control. The collection of pollen from cherry forms to determine fertility was carried out during the period of mass flowering of trees in the first ten days of May. The anthers removed from the flowers were dried at room temperature, opened, and the spilled pollen was poured into parchment paper bags and stored in a desiccator over calcium chloride. Fertility was determined by the method of pollen staining with acetocarmine. According to the research results, it was established that, on average, over 2 years of research, cherry accessions 84847, 84854, 84735 stand out for a high degree of pollen fertility (more than 58.64 % in almost all forms), which makes it possible to recommend them for use in crosses to obtain new hybrids . The highest degree of fertility was observed in pollen of the control variety Turgenevka — it was 76.80 % on average over two years. The lowest fertility was observed in the sour cherry form 84595. In this case, it was only 29.61 %.

The article presents the results of a long-term study in the conditions of the Orel region of seven varieties of sour cherry, bred in diff erent years in the Tatar Research Institute of Agriculture: Naumovskaya, Zarya Tatarii, Pamyat Sakharova, Truzhenitsa Tatarii, Tveritinovskaya, Shakirovskaya and Sevastyanovskaya. The varieties were graft ed in stone fruit stands of the Russian Research Institute of Fruit Crops Breeding (RRIFCB, Orel) in 2009. The study was conducted in order to determine the suitability of growing of indicated varieties in the conditions of the Orel region and the possibility of its recommending as sources of economically valuable traits for breeding. The RRIFCB Businka variety was used as a control accession. The study was started in 2010 and lasted until 2018 inclusive. According to the results of research, it was found that all the studied varieties in general correspond to the natural conditions of the Oryol region and can be successfully cultivated in this region. Individual varieties were positively distinguished by a number of parameters. The varieties Pamyat Sakharova and Naumovskaya had the highest fl owering among all the studied accessions. The maximum general degree of fl owering and fruiting stood out for the Truzhenitsa Tatarii variety. Among the studied accessions, all showed a high degree of resistance to the main fungal diseases of this zone – coccomycosis and moniliosis – and did not show a lesion stronger than 2.0 points. Winter hardiness was also relatively high among all the studied accessions, but the varieties Tveritinovskaya, Pamyat Sakharova, and the control variety Businka showed themselves best on this trait. Varieties Sevastyanovskaya and Pamyat Sakharova showed the highest degree of general condition. The variety Pamyat Sakharova, which showed the most positive results in the majority of the studied parameters, can be recommended for cultivation in the production conditions of the Orel region and for further breeding research on sour cherry.

The aim of the research was to establish the features of the inheritance of the size of the fruit in the hybrid families of Prunus domestica. The objects of study were hybrid seedlings of plum selection of the Tatar research Institute of agriculture. Fruit sizes were estimated according to the methodology of the all-Russian research Institute of fruit crops selection. The analysis of the splitting of plum in hybrid families by the size of fruits showed that seedlings with small fruits dominated in the breeding gardens of the Tatar research Institute. The size of the plum fruit is controlled by polygens. All of the original parental forms are heterozygotes for the genes determining the size of the fruit. A small fruit is a dominant trait, a large fruit is a recessive trait. In most hybrid families, plum seedlings have a significant variability in the size of the fruit. Transgressive genotypes with large fruits are formed in hybrid families Eurasia 21 x Renklod Tenkovsky, Eurasia 21 x free pollination and Zyuzinskaya x free pollination. The varieties Eurasia 21 and Zyuzinskaya must be used as sources in breeding of plums for large-fruited.

Relevance. One of the most important directions in the breeding and variety study of fruits, in particular domestic plum European, is the breeding of cultivars with high commercial and consumer qualities of fruits. In this regard, the assessment of some commercial and consumer qualities of fruits in plum cultivars of the RRIFCB gene pool was of great practical and scientific interest. Material and methods. As objects of research, we used 8 plum cultivars of the RRIFCB gene pool and a control cultivar of the RRIFCB breeding Bolkhovchanka. The studies were carried out on the basis of the laboratory of breeding and variety study of stone fruit crops of RRIFCB in 2015-2019. Determination of color, shape, average weight, taste, size of fruit, size and shape of the stone, density of pulp, separation and length of the stalk, color of the juice were carried out in accordance with the "Program and methodology for the variety study of stone fruit crops" and "Pomology". Results. Most of the studied plum cultivars from the gene pool of the Russian Research Institute for Fruit Crops Breeding have valuable commercial and consumer qualities of fruits, which will allow them to be used in further breeding for this trait. Cultivars Californiyskaya krupnaya, Zarechnaya rannyaya, Volgogradskaya can be recommended for further use in breeding as sources of high fruit mass. Cultivars Californiyskaya krupnaya and Bolkhovchanka can be recommended for further use in breeding as sources of high pulp content in fruits and fruit sizes. On the basis of the tasting assessment of the fresh fruits, the fruits of the cultivar Volgogradskaya stood out positively.

The paper presents the results of technological evaluation of red wine varieties breeded by All-Russian Research Institute for Viticulture and Winemaking: Vesta, Cherny, Zhemchug, Au-gusta, Teremnoy, Mugofir. These varieties are characterized by high sugar accumulation. Li-queur wines were prepared using classical tech-nology. The research was conducted in the la-boratory of wine technology in micro-wine production. The weight of one batch of grapes was 10–25 kg. The main physical and chemical parameters of wort and wine were determined. Wine distillate was used as an alcoholic agent. For maintaining and enhancing the varietal aroma of grapes we used technology of frac-tional alcoholization. With the help of degusta-tions, organoleptic characteristics of the ob-tained samples of liqueur wines were carried out, as a result of which preliminary conclusions were made about the feasibility of using the studied varieties for the preparation of red li-queur wines. All the studied grape varieties can be recommended for the production of liqueur wines, pink and red.
