title: Vitamin C and reducing sugars in the world collection of Capsicum baccatum L. genotypes.
abstract: This study aimed to analyze 123 genotypes of Capsicum baccatum L. originating from 22 countries, at two stages of fruit development, for vitamin C content and its relationship with reducing sugars in fruit pericarp. Among the parametric population, vitamin C and reducing sugar concentrations ranged between 2.54 to 50.44 and 41-700mgg(-1) DW of pericarp, respectively. Overall, 14 genotypes accumulated 50-500% of the RDA of vitamin C in each 2g of fruit pericarp on a dry weight basis. Compared with ripened fruits, matured (unripened) fruits contained higher vitamin C and lower reducing sugars. About 44% variation in the vitamin C content could be ascribed to levels of reducing sugars. For the first time, this study provides comprehensive data on vitamin C in the world collection of C. baccatum genotypes that could serve as a key resource for food research in future.
