Current status and research progress of red-fleshed fruit germplasm
Red-fleshed fruits are abundant in anthocyanins and possess high nutritional and health benefits,which are increasingly favored by more and more consumers and breeders.In this article,the common red-fleshed germplasms were reviewed,including the main red-fleshed culti-vars in fruit production.Anthocyanin components were summarized in different red-fleshed fruits,and their difference in red-fleshed and white-fleshed fruits was analyzed.The application of red-fleshed resources as intermediate materials in breeding was evaluated,and their potential applica-tion in health products,medical industry and cosmetics industry was summarized.Based on the pathway of anthocyanin biosynthesis,the mechanism underlying anthocyanin accumulation in flesh was reviewed.In the end,the main problems,development trends and potential applications of red-fleshed fruits were discussed.
