One of the most promising trends in apple breeding is polyploidy. Triploid cultivars show higher fruiting stability and increased self-fertility. The easiest way to obtain triploids is to cross diploid and tetraploid cultivars among themselves. The main limiting factor in this case is a restricted number of initial tetraploid forms whose characteristics affect the quality and prospects of the resulting hybrid progeny.The staff of Sverdlovsk Horticultural Breeding Station in the Middle Urals produced and analyzed 5 hybrid families using cv. ‘Papirovka tetraploidnaya’ as the paternal source; the latter’s pollen was supplied by Acad. E. N. Sedov from the All-Russian Research Institute of Fruit Crop Breeding. Ninety hybrid seedlings were studied.The study showed that ‘Papirovka tetraploidnaya’ with a high degree of probability conveyed the following traits to its progeny: large fruit size, fruit ripening in early summer, midsummer and autumn, loose or medium density of coarse fruit flesh, and nonoutstanding fruit taste (scoring 3.8–4.2 points).

The results of the analysis of long-term trends in changes in individual climatic characteristics and variations in weather conditions of the growing season in the forest-meadow zone of the Middle Urals for the period from 1958 to 2020 are presented, their influence on the choice of hybrids and some elements of corn cultivation technology are estimated. As a result of calculating the linear trend, a statistically proven trend has been established to increase the sum of active temperatures above 10 °C for May – September. At the same time, random fluctuations of the analyzed parameters over the years have a direct impact on corn development and productivity, and the limiting factor is the lower limit of these fluctuations, the values of which increase throughout the analyzed period. Nevertheless, the variation over the years remains strong, and the lower limit of these fluctuations does not reach the minimum level for the stable maturation of early-maturing corn hybrids. Therefore, for the conditions of the Middle Urals, the previous recommendations concerning the selection of corn hybrids for early maturity, cold resistance and drought resistance remain relevant. At the same time, the revealed climatic trend allows to predict an increase in the probability of obtaining feed with a high content of exchange energy, which characterizes it as positive one.

A careful 63-year-old work on apple breeding, resulting in the creation of 54 its varieties, included in the State Register of breeding achievements admitted for use, makes it possible to speak about the ways of reduction in the time of the actual breeding process and the subsequent stages of accelerating the introduction of new varieties into production. According to the experience of the Russian Research Institute of Fruit Crop Breeding, an average of 19 years is spent from hybridization to the adoption of a variety for State trials, and from hybridization to inclusion in the State Register it is spent 27 years. The requirements for new apple varieties are changing and becoming tougher to a large extent during this period. We off er the possibility of reducing the time to create a new variety by combining in time the actual breeding process and the primary variety study. For this purpose already during the selection and transfer of biannual seedlings to the breeding orchard it is necessary to multiply and include the best seedlings on morphological features with a culture of 5 points (no more than 1 seedling per thousand selected ones) in the primary study. In this case the actual breeding process is combined with the primary study. When transferring the variety to the state trial, it is necessary to lay orchards of a small production testing of 20-40 trees of a new variety in each of the three replications. The time of single breeders is a thing of the past. To create varieties that meet high requirements of production (convenient for cultivation, highly adapted to local conditions, with a certain shape of tree crowns, with the fruits of high commodity and consumer qualities), interdisciplinary teams are needed, which include not only breeders, but also pomologists, geneticists, cytoembryologists, biochemists, physiologists, phytopathologists, and agricultural technicians. Usually years, and sometimes decades are spent on the creation of well-coordinated teams of professionals of diff erent specialties, but only such teams are able to create varieties that meet all main requirements. At Russian Research Institute of Fruit Crop Breeding such a team consists of 22 people.

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.

Russian Research Institute of Fruit Crop Breeding (VNIISPK) is the main supplier of new apple cultivars for the middle zone of Russia. 54 zoned apple cultivars of different dates of maturing have been created at the Institute and included in the State Register of breeding achievements. The reasons of a very long period from the beginning of the breeding process (hybridization) to the wide introduction of a cultivar into broad production are considered in this pa-per. Examples of acceleration and intensification of the breeding process are given. If in 1950s at VNIISPK it took 39-49 years (43, on the average) from the hybridization to transfer a cultivar to the State Register, then in 1980s-1990s it took just 18-23 years (21, on the average). The techniques and methods of reducing this period are given in this paper. Often not less period passes from the inclusion of a cultivar in the State Register (zoning) before introduction of a cultivar in wide production. To reduce this period, it is proposed in the original institution to lay plots of small production cultivar testing of 20-30 trees in each of the 3 repetitions (60-90 trees) for each new cultivar and the control cultivar simultaneously with the transfer of a cultivar to the State Register.

Abstract. The results of the state testing of red currant varieties in the Prokopievsky Fruit-Berry State Station of Variety Testing (West-Siberian region) in 2015–2017 are presented. The task of the research was to test the Russian Research Institute of Fruit Crop Breeding red currant varieties in the soil-climatic conditions of the West-Siberian region. Methods. 13 varieties from the All-Russian Research Institute of Fruit Crop Breeding (Orel region), 5 varieties from the Novosibirsk Zonal Fruit-Berry Experimental Station (Novosibirsk region) and 3 varieties from the South-Urals Research Institute of Fruit and Potato Growing (Chelyabinsk) were studied. The red currant variety “Red Cross” in the West-Siberian region was taken as a standard. The observations and records were carried out according to the Methods of the state variety testing of agricultural crops. Results. For three year of the study, on the average, the productivity of the standard was 63.3 centner per hectare. The varieties from the former Novosibirsk Zonal Fruit-Berry Experimental Station “Valensiya”, “Khrustyashchaya” and “Eliza” were on the same level of productivity with the standard, while “Rozita” was inferior to the standard. The varieties from the South-Urals Research Institute of Fruit and Potato Growing significantly exceeded the standard in terms of the crop load: “Ilyinka”, “Ural’skaya krasnaya” and “Ural’skaya belaya” (93.3–84.4 centner/ha). The varieties from the All-Russian Research Institute of Fruit Crop Breeding had higher rate of productivity: 122.5 centner/ha (“Marmeladnitza” – 102.6 centner/ha (white-fruit variety “Belka”). “Gollandskaya krasnaya”, “Khrustyashchaya”, “Belka”, “Uralskaya belaya” and “Roza” are characterized by a dessert taste (5.0 point). In conditions of the Kemerovo region the varieties “Asya”, “Dar Orla”, “Dana”, “Ilyinka”, “Marmeladnitza”, “Orlovchanka”, “Podarok leta”, “Ural’skaya krasavitsa”, “Niva” and “Belka” are characterized by large size of fruit with maximal berry weight of 0.9–1.3 g. “Ilyinka”, “Marmeladnitsa”, “Ural’skaya krasnaya”, “Belka” and “Ural’skaya belaya” demonstrated a complex resistance the main diseases of red currants- anthracnose and septoria. Scientific novelty and practical importance. The results of the introduction showed that the All-Russian Research Institute of Fruit Crop Breeding red currant varieties have high environmental adaptability to the conditions of the sharply continental climate. As a result of the testing, the varieties “Asya”, “Dana”, “Marmeladnitsa”, “Orlovchanka”, “Dar Orla” and “Podarok leta” (Orel breeding) are included in the State Register of breeding achievements admitted for use in the West-Siberian region.
