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.

Abstract. The purpose of the research is to characterize the varieties of long-legged flax included in the State Register of Breeding Achievements in terms of resistance to fusarium wilt, rust, anthracnose and pasmo. The research was conducted in 2018–2020 in vegetative, laboratory and field conditions at the All-Russian Research Institute of Flax (currently: A separate division Research Institute of Flax). As an object of research, we used varieties of flax-long-legged flax included in the State Register of Breeding Achievements of the Russian Federation for 2018–2020. Methods. The studies were carried out using modern mycological and phytopathological methods. Laboratory, vegetation and field experiments were conducted according to the All-Russian Research Institute of Flax methods. Results and practical significance. Among the studied 66 varieties, 56.1 % were highly resistant and resistant genotypes to fusarium wilt and 58.3 % – to rust. The specific weight of the Flax Institute varieties for this period was 34.8 %. High resistance to rust and fusarium wilt was characterized by the VNIIL selection varieties: Universal, Diplomat, Alexim, Dewdrop, Zaryanka, Aleksandrit. For the first time, scientists of the Flax Institute have created varieties of flax-long – legged (Diplomat and Tonus) resistant to three diseases: rust, fusarium wilt and anthracnose, and the Caesar variety-to four diseases. All varieties, with the exception of Diplomat and Tonus, a selection of the Flax Institute, were susceptible to anthracnose. The Grant variety of the selection of the Republic of Belarus and the Caesar variety were resistant to pasmo by 59.7 %, the rest were characterized by resistance to damage by 27.8–42.0 %. Scientific novelty. The characteristics of the resistance of the varieties included in the State Register of Breeding Achievements of the Russian Federation are comprehensively described on infectious and provocative backgrounds using natural and synthetic populations of pathogens diseases of flax. Varieties with group resistance to 2, 3, and 4 diseases are identified. The use of flax varieties resistant to the most economically dangerous diseases in flax crops will reduce the infectious potential and its accumulation in nature.

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.

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 yield of black currant is one of the most important economic indicators of the variety. It is determined by many factors; one of them is morphological features of a bush: the number of main branches, length of shoots, the number of tassels (bunches), the number of berries in the bunch and the mass of berries. The article explores differences in the real and prospective productivity of new black currant hybrids in the selection of Far-Eastern State Agrarian University. The researchers investigated two hybrids, identified by the results of many years research in the selection garden. Novosel variety was chosen as a control one as it has higher taste properties of berries and productivity than other zoned variety Amurskiy konservnyy. The research was carried out in accordance with the program and methods of variety study of fruit, berry and nut crops, developed in Russian Research Institute of Fruit Crops Selection in 1999. Prospective productivity of new hybrids of black currant is much higher than that of the control variety Novosel. New varieties of black currant have longer fruit-bearing shoots and greater number of bearing nodes. Otherwise, the real yield does not differ significantly from the control one. The differences in real and prospective productivity are mainly determined by external factors. This indicates the necessity to develop varietal agricultural machinery that reduces crop losses.  The article highlights the reasons that result in decrease in the real productivity of black currant. They are high temperatures in the ripening period. One of the studied hybrids (9-26) is promising for horticulture in Amur region, as it has bigger berries than that of zoned varieties.

The All-Russian Scientific Research Institute for Breeding Fruit Crops is the oldest pomological institution. The scientific direction of the institute is to obtain genotypes of fruit crops that exceed the standard ones in terms of basic economic indicators, including those with an improved chemical composition of fruits. The leading culture is the apple tree. One of the indicators of the chemical composition of apples is the presence of phenolic compounds, the most important natural antioxidants: catechins and polyphenols. Genotypes of different maturation periods, immune (Rvi6) and resistant (Rvi5) to scab, diploids (2x) and triploids (3x), vigorous and intensive type (Co gene), were identified as sources of the studied traits. The best in terms of the accumulation of catechins were the varieties of the autumn ripening period: Sokovinka, Slavyanin, Pamyat Isaeva, Zaryanka, Orlovsky pioneer, origin Antonovka red barrel × SR0523 (159.0-288.0 mg / 100 g); the summer varieties Zhelnoe, Orlovim, Early aloe, Anniversary (152.0-170.0 mg / 100 g), the winter varieties Kurnakovskoe, Olympic, Poetry, Freshness, Bezhin meadow, Kulikovskoe, Start, Health, Academician Savelyev, Festive, Orlovskaya Zarya, Pamyati Blynsky, Vita, Mars, Imrus, Pamyati Semakina, Celandine, Kandil Orlovsky, Morning Star, (161.2-353.5 mg / 100 g). The sources of the total amount of polyphenols (more than 400.0 mg / 100 g) were selected: with the Rvi6 gene Start, Zaryanka, Ivanovskoe, Imrus, Oryol woodland, Zdorov’e, Bolotovskoe, Pamyati Khitrovo, Kandil Orlovsky; with the Rvi5 gene Orlovsky pioneer and Celandine; triploids Memory Semakin, Bezhin lug, Turgenevskoe, Mars, Orlovsky partisan, Trainer Petrov, Patriot, Augusta (404.0-623.9 mg / 100 g), of which the varieties Mars and Trainer Petrov have the Rvi6 gene.
