Abstract: Begonia fruit is rich in sugar and acid, vitamins, tannins and other functional ingredients, and has broad application prospect in the development of functional food. The study selected 48 hybrid Begonia strains of fruit, investigated the main appearances of the fruit and determined the functional components: total soluble sugar, titratable acid, vitamin C and tannins content. According to the performance of the comprehensive character, the author screened out superior system of high functional ingredients and good appearance quality. The results showed that the functional ingredients in Begonia fruit were significantly higher than those in apple fruit. And the contents of total soluble sugar, titratable acid, vitamin C and tannins could reach 1.86, 2.23, 6.72 and 33.4 times of that in apple fruit respectively. The selected strains can be regarded as hybrid parents with apple, to improve the nutrition and taste of apple fruit, and also have certain reference value for cultivating comprehensive agronomic characters of fine varieties.
