| Summary: | Rosehips fruit contains organic and inorganic substances, the most valuable compounds among organic substances are vitamins, which are accumulated in the flesh of the fruit, and they have important physiological effects for living organisms. The obtained experimental data were statistically processed by the method of analysis of variance. Many selected varieties of rosehips were unique not only in the size of the fruit, but also in the high seed yield: an average of 28.7 ± 0.65 pieces in the fruits of “Sijjak-5”, 29.1 ± 0.66 pieces in the fruits of “Sijjak-6”, 33.9 ± 0.93 fruits in “Sijjak-7”, 28.7 ± 0.66 fruits in “Sijjak-15” and 29.3 ± 0.64 fruits in “Burchmullo-18”. Rosehips seeds contain “rosehips oil”, which contains 10 mg% carotene, 200 mg% vitamin E, linoleic (56.71%) and oleic (29.32%) acids. “Sijjak-3”, “Sijjak-6”, “Sijjak-12” and “Chimgan-19” were selected as promising varieties, taking into account the valuable economic and biological characteristics of the fruit, such as size, productivity and fertility. Varieties “Parkent-21” and “Parkent-24”, according to the size of fruits and the amount of fruit flesh, whereas Parkent-26, “Kumushkon-29”, “Parkent-23”, “Chimgan-31”, “Koronkul”-32 were classified as promising varieties based on the highest yield.
