Abstract: In order to analyze genetic rule on vitamin C (Vc) of pepper, the pepper variety L5 having high vitamin Vc and L158 including low vitamin were used as female and male, respectively. And Vc content in pepper fruit was carried out. Accordingly, the correlation between Vc content of fruit and related traits was analyzed according to six generations. The results showed that Vccontent in exhibited continuous variation trends and was quantitative trait controlled by multiple genes. In addition, Vc content was significantly positively correlated with average weight of single fruit and was a significant negative correlation with the thickness of fruit fresh. And Vc content and fruit longitudinal diameter, fruit diameter and soluble solids have no relevant relationship. It belongs to C-O model similar to the additive - dominant - epistatic genetic hybrid genetic model.
