Abstract

The research was aimed at evaluating sweet cherry forms on a complex of economically valuable traits and the allocation of promising genotypes for further use in breeding and production. The forms of sweet cherries grow in Michurinsk city of Tambov region. The study of frost resistance was carried out in laboratory conditions. Annual branches were frosted for 12 hours at -32°C and -35°C. Reproductive buds in all studied forms were characterized by reversible damage (less than 3 points) at temperature regime -32°C and complete death at -35°C. 10-117 form was characterized by -35°C frost resistance in the middle of winter, in which the freezing degree of annual branches tissues and vegetative buds did not exceed 2 points. Over the years of research, elites 4/8-24, 10-115, 7-38, 10-117, 6-87, 4/9-15, 7-5 possessed resistance to moniliosis and coccomycosis (the damage degree not more than 2 points). The highest yield (9.75-9.84 t/ha) on average over three years was shown by forms 4/8-24, 7-38, 7-5. Yield at the control level was noted in forms 6-87, 4/9-15, 10-115. Elite forms 4/9-15, 7-38 were characterized by the largest mass of fruits, significantly exceeding the control variety. The average weight amounted to 7.3 and 7.2 g, and the maximum was 9.4 and 8.4 g respectively. Forms 4/8-24, 4/9-15, 7-38 combined the dessert taste of fruits (tasting assessment of 4.6-4.8 points), very juicy and dense pulp.

Highlights

The agro-industrial complex is one of the key industries of the Central Chernozem region
In 2018, Belgorod, Voronezh, Kursk, Lipetsk, Oryol and Tambov regions accounted for about 27% of meat, 8% milk and eggs, 20% grain
This paper presents the results of a comprehensive assessment of sweet cherry forms promising for cultivation in the CCR conditions

Summary

Introduction

The agro-industrial complex is one of the key industries of the Central Chernozem region. The constituent CCR areas are among the most promising regions in terms of AIC development. In 2018, Belgorod, Voronezh, Kursk, Lipetsk, Oryol and Tambov regions accounted for about 27% of meat, 8% milk and eggs, 20% grain. The average indices of the industry growth rate amounted to 3.5% with recession (-0.2%) for the country as a whole [1]. The positive development dynamics of livestock and crop production of the Central Chernozem region continued in 2019. The average yield of grain crops exceeded the average Russian indicators by 40 -50%, and 5 -10% - yield in the south of the country [2]
