We have investigated the content of very important bioactive compound such as vitamin C in fruits of six varieties of Chinese jujube progenies: Zu tao czao, Da bai czao, Kitaiski 2A, Wild midleasian jujube type, Ja czao and Vahshski 45-2. It has been studied the inheritance of the vitamin C content in the fruits of 131 types in progenies, which were obtained from crossing of those six Chinese jujube varieties by open pollination, considering of the high jujube variety self-incompatibility. Studies were done on the plants that were 7-9 years old, or in full fertility. Fruits from variety Da bai czao have the highest content of vitamin C (370.7 mg/100 g fruit). Compare with the other varieties, the fruit from variety Kitaiski 2A is characterized with the lowest content of vitamin C (185.2 mg/100 g fruit), and it’s progeny, on the contrary, is characterized with the highest content of vitamin C in average (290.8 mg/100 g fruit), compare with the other investigated progenies. The largest number of the types in progeny with content of vitamin C higher than 300 mg/100 g fruit were characterized the varieties Zu tao czao and Da bai czao.
