“…Frost modelling of -25 °C after a three-day thaw at 2 °C allowed identification of reactions of cultivars to thaw. The previous conclusion that Finnish cultivars did not have the ability to maintain stability during thaws (Linden et al, 1999) was confirmed only partially and largely depended on the duration of the thaw and the severity of the frost (Krasova et al, 2020).…”

The goal of our work was to assess the ability of hybrid apple seedlings and their parent forms to maintain frost resistance during the thaw period, by using artificial freezing methods. Apple resistance was studied in the laboratory by modelling the damage factors of the frost resistance component III with the use of a climatic chamber. All of the studied hybrid apple seedlings from all used crossing combinations showed a sufficient level of frost resistance under modelling of a three-day artificial thaw (+2 °C) with subsequent temperature lowering to –25 °C. The damage of bark, cambium and wood in all of the studied hybrid seedlings was reversible and did not exceed a 2.0 point rating on a 5-point scale. The temperature rise up to +2 °C during three days in February did not cause the activation of growth processes in buds and bark and did not dramatically affect hybrid apple seedlings. According to the results of the artificial freezing, hybrid apple seedlings of the 6026 family (‘Imrus’ × ‘Krasa Sverdlovska’) and hybrids of the 6030 family (‘Svezhest’ × ‘Pepin Orlovsky’) showed the largest potential frost resistance after a thaw in winter.

The apple tree gene pool was evaluated by resistance to adverse winter conditions based on the analysis of weather data for 50 years. 70% of winter-hardy and highly winter-hardy cultivars were revealed in the group of traditional local cultivars. Many local Central Russian cultivars are widely used in the breeding of new winter-hardy cultivars in central Russia, the Volga region, the Urals, Siberia, the Altai, the Far East and the south of the country. Positive results were obtained by using cultivars obtained from stepped crossbreeding, combining a complex of valuable qualities (winter resistance, immunity to scab, high qualities of fruits) in selection. On the basis of damaging factors' modeling, resistance to -38° C temperature and resistance to frost after thaw were confirmed in most VNIISPK breeding cultivars; winter-hardy cultivars with a resistance threshold -40°C: Vyatich, Orlovskiy partizan, Orlovskoye polesie, Zdorovye, Ministr Kiselev, Pamyat' Semakinu, Rozhdestvenskoye. Cultivars Idared, Golden Delicious, Granny Smith, Gala, Jonagold, Pink Lady, Fuji, Honeycrisp are recommended for use in breeding in combination with winter-resistant cultivars to create new high-quality apple tree cultivars with long keeping quality.

The study results of the main economic and biological indicators of summer ripening apple varieties on low-growing rootstocks in intensive plantings were generalized. It was found that the use of low-growing intercalars has the same weakening effect on the apple tree growth as when using it as a rootstock. In terms of the total yield, 10-year-old trees of the Orlinka and Yablochny Spas varieties did not show significant differences in the options for using low-growing forms in as an intercalary or root stock. Modeling the damaging factors of the winter period revealed good resistance to early winter frosts, to a decrease in the freezing temperature in the middle of winter to -40 °C and to frosts after thaws at the end of winter. On the medium-sized rootstock 3-3-72, Rannee Aloe variety showed high early ripening and productivity significantly higher than Papirovka. The highest yields of the studied varieties on the rootstock 3-3-72 were given at the age of 10 to 20 years and are characterized as mildly periodically fruiting. According to the complex of economic and biological indicators, the varieties of summer ripening period for intensive plantings, farm and homestead gardens were identified.
