Comprehensive assessment of new promising varieties of sweet cherry of Dagestan breeding

Relevance . The creation of new varieties with a complex economically valuable and biologically traits is an urgent direction breeding research, updating expanding the assortment cherries. Methods characteristics economic biological properties description eight cherries Dagestan selection are presented: Pokrovskaya Memory, Buinakskaya black, Maral, Elite form 129/1, Leningrad Guards, Dolores, Pearl Late Lermontov. were examined using biochemical methods analysis standard variety study. Results It was determined that all studied cherries, except Memory variety, characterized by significant content soluble solids (13.7–17.9%), sugars (10.1–13.2%) acids (0.40–1.12%) in fruits. Large–fruited (7–9 g), good tasting ratings (4.8–5.0 points) Buinak 129/1. Lermontova, Maral Dolores highly resistant to spring frosts (the freezing flowers did not exceed 17.5%). fruits black cherry, Lermontov most cracking (from 8.0 18.0%) during ripening at high humidity. New susceptible coccomycosis monilial burn, but Guards distinguished themselves low resistance rot (21–23% lesion). basically consistently yields, improved commodity consumer environmental stressors.
