Abstract
The article presents the analysis results of the breeding suitability of two Far Eastern pumpkin varieties, Nadezhda and Vnuchka, according to key biochemical, consumer and technological indicators, with a view to their possible use as functional food products. The results show that the biochemical parameters of these varieties’ fruits are unstable and varied depending on the hydrothermal conditions of the year. Both varieties are high in vitamins with an average ascorbic acid content of 10.12 mg% (Nadezhda) and 11.71 (Vnuchka) mg%. The total sugar content in both varieties is almost equivalent, with an insignificant difference of less than 1%. However, the Nadezhda variety has a higher yield. It was found that both studied varieties are suitable for the production of functional products according to the main test indicators in the conditions of the Middle Amur region. Nevertheless, the Nadezhda variety is characterised by shorter periods favourable for processing raw pumpkin materials of 1–2 months after harvesting, while the Vnuchka variety can be processed 1–4 months after.
