Content of biologically active substances in fruits of hybrid peaches included in breeding pool of the Nikita Botanical Gardens
For several decades, the Nikita Botanical Gardens has been working on breeding new promising peach cultivars. New cultivars must exhibit better characteristics than the existing ones. Modern horticulture needs peach cultivars with such properties as good commercial qualities of fruits, early bearing age, resistance to diseases, high and stable yields. High-quality fruits must have an attractive appearance, excellent taste properties, ensure ease of transport and have a high content of biologically active substances. The solution of these problems makes possible the obtaining of economically high efficient cultivars for implementation into industrial horticulture. The breeding process included several researches on detecting biologically active substances in mesocarp of peach plants studied, which were obtained through purposeful hybridization. The analysis showed that the solids content in fruits of researched hybrid plants varied between 13.30% (in the seedling 7/43) to 19.70% (7/43). The fruit flesh showed a low content of ascorbic acid (6.60 to 13.20 mg 100 g‑1). Its maximum content emerged in fruits of the hybrid form 2/18. The total number of organic acids in fruits varied from 0.43% (7/73) to 0.57% (7/43). The total concentration of phenolic compounds in fruits varied from 150 mg 100 g‑1 (4/43) to 465 mg 100 g‑1 (7/43). Maximum concentration of leucoanthocyanins in fruits showed the peach seedling 7/43 (456 mg 100 g‑1) and of flavons NDASH the seedling 4/43 (144 mg 100 g‑1). The seedling 7/43 proved to be promising for further investigation and involving in the breeding, thanks to maximum complex content of biologically active substances in fruits.
