In this paper, we evaluate strawberry varieties of different geographical origin in terms of anthocyanin content in fruits under the conditions of a particular region with the purpose of identifying valuable genotypes for inclusion in further breeding work and practical use. The research was conducted in 2015–2020 at the Kokino collection site of the Federal Research Center for Gardening, located 24 km south-west of the city of Bryansk, in the village of Kokino, Vygonichsky district, Bryansk region. The effect of genotype and weather conditions on the accumulation of anthocyanins in strawberry fruits was studied. The research objects included 35 strawberry varieties of domestic and foreign breeding. Observations were carried out in accordance with the conventional methodology for varietal study of fruit, berry and nut crops. Fruits for the analysis were collected in dry sunny weather, at the stage of optimum maturity. Anthocyanin content in fruits was determined according to the color scale developed by A. A. Zubov and K. V. Stankevich in Michurin Research Institute of Genetics and Fruit Plant Breeding. Most of the varieties (57.1%) were characterized by medium variability of the indicator by year (V = 10–20%). The varieties Sudaruska (24.9%), Darselekt (24.2%), Polka (20.2%), Mieze Schindler (34.1%), Tenira (28.3%) showed a high dependency of fruit anthocyanin content on climatic conditions during the ripening period. The varieties with dark-coloured fruits were found to be Rubinovy Kulon, Barynya, Tsaritsa and Amulet. Their coloring was associated with high anthocyanin levels (more than 80 mg/100 g). These varieties comprise a valuable source material for further breeding and practical use.

The paper presents the results of research for 2022–2023, as well as the analysis of the effect of prolonged negative late spring temperatures on garden strawberry on May 8-12, 2023. The research was aimed at evaluating garden strawberry varieties for a complex of economically valuable characteristics after exposure to prolonged late spring frosts on May 8–12, 2023. Objects of study included 14 garden strawberry varieties of foreign selection: NF 421, ‘Festivalnaya romashka’, ‘Florida Festival’, ‘Verona’, ‘Dely’, ‘Joli’, ‘Senga Sengana’ (k), ‘Sweetheart’, ‘Syria’, ‘Cabot’, ‘Elianni’, ‘Malvina’ and 2 varieties selected by the Institute: ‘Zvezdochka’ (k), ‘Zhanna’. The plants were planted on May 6, 2022, the survival rate accounted for 100%. The research was conducted in the Research Institute of Horticulture and Medicinal Plants “Zhigulyovskie sady” (Samara, Russia) on the collection variety plot in accordance with the generally accepted program and methodology of varietal study of fruit, berry and nut crops. The analysis of weather conditions for 2022–2023 was performed using the data of the Volga Department for Hydrometeorology and Environmental Monitoring (UGMS), with additional data obtained from the temperature and humidity control system located on the test plot in Malaya Tsarevshchina, Krasnoyarsky District, Samara Oblast. The varieties ‘Verona’, ‘Zvezdochka’ (k), ‘Cabot’, ‘Sweetheart’, ‘Festivalnaya Romashka’, and ‘Malvina’ demonstrated the highest resistance to late spring frosts according to the complex of characteristics. The main part of the varieties had 28-33% damage to flowers and buds. The highest damage figure was revealed in the variety of the average maturity period NF 421 and the early variety ‘Zvezdochka’ (k). The late variety ‘Malvina’ did not suffer from frost.The lowest degree of fruit deformation was observed in the varieties ‘Sweetheart’, ‘Zvezdochka’ (k), and ‘Malvina’. The greatest degree of freezing after exposure to low temperatures on May 8-12 was observed in the varieties ‘Dely’, ‘Joli’, ‘Florida Festival’ and ‘Elianni’. The best adaptive capacity according to the results of overall plant condition for the period 2022-2023 was shown by the varieties ‘Verona’, ‘Zvezdochka’ (k), ‘Senga Sengana’ (k), ‘Cabot’, ‘Sweetheart’, ‘Syria’. The highest average berry weight was recorded in NF 421 (19.5 g/bush). The highest productivity was observed in later ripening varieties – ‘Malvina’ (261.4 g/bush) and ‘Cabot’ (241.0 g/ bush), as well as in the control variety ‘Seng Sengana’ (k) (197.1 g/bush). The lowest indicators were reported in ‘Dely’ (50.1 g/bush) and ‘Florida Festival’ (29.0 g/bush). The genotype was revealed to influence the resistance to low late spring temperatures and recovery ability of plants after late spring frosts.
The results of the study of 20 new strawberry cultivars at the collection site of the VNIISPK located in the Orel region are presented. The studies were carried out in 2021–2022. Records and observations were carried out according to the requirements of the Program and methodology of variety study of fruit, berry and nut crops, section “Strawberries”. The data on the components of productivity and yield are given. The cultivars are ranked by the timing of flowering and maturation. The complex of economically valuable traits and properties was comparatively assessed. The dates of the passage of the main phenophases were determined. Vegetation began on April 10–15. The extension of inflorescences fell on the period from April 26 to May 3. Flowering began on May 14–15, fruiting was from June 12–18 to July 20. The sum of effective temperatures at the beginning of the growing season was 72 °C – 97.5°C. The mass extension of inflorescences in accounting years occurred at the sum of effective temperatures of 148–149° C. Flowering began at the sum of effective temperatures of 214–240° C, mass flowering took place at the sum of effective temperatures of 324–424° C. The effective temperature range at the beginning of fruiting was 583–686° C in 2022–2023, at the time of mass fruiting – 639–737°С. According to the results of the study, the most large-fruited cultivars were identified: Brilla (20.3 g), Raurica (20.4 g) Amy (21.0 g) and Quicky (25.5 g); cultivars containing 10 or more peduncles: Malling centenary and Sonsation. Cultivars with more than 50 ovaries per bush are of the greatest breeding value. These requirements were met by Roxana (51.1 pcs.), Sonsation (51.8 pcs.), Jive (52.2 pcs.), Rumba (52.5 pcs.), Raurica (53.6 pcs.), Malling centenary (55.4 pcs.), Kent (75.7 pcs.) and Vivaldy (63.2 pcs.). High-yielding cultivars were identified: Raurica (541.7 g), Quicky (563.2 g), Roxana (619.8 g) and Malling centenary (635.7 g).
