摘要: In this study, we measured the anthocyanin composition and content in the 'Kyoho' grape cultivar and its derivatives via ultra-performance liquid chromatography-mass spectrometry and characterized the MybA-related genes at the color locus via capillary electrophoresis and quantitative real-time polymerase chain reaction. A total of 30 anthocyanins (15 monoglucoside and 15 diglucoside) were detected. Peonidin-3-O-(t-6 ''-O-coumaroyl)-glucoside-5-O-glucoside was the most abundant component, and the content of malvidin-3-O-(c-6 ''-O-coumaroyl)-glucoside-5-O-glucoside was low in all cultivars. All 49 cultivars contained VvmybA1, VvmybA2, and VvmybA3, whereas only the black-skinned cultivars contained VlmybA2. The anthocyanin content in the cultivars that contained VlmybA2 was significantly higher than other cultivars. These results could provide information for future color breeding programs in grapes.
