Blueberries are rich in anthocyanins and have significant nutritional and health values. Increasing the anthocyanin content in blueberry fruits is of great significance for nutritional fortification and the development of functional foods. This article systematically analyzes the genetic characteristics and breeding strategies of blueberry germplasms with high anthocyanin content. Firstly, characterize the diversity of anthocyanin phenotypes in blueberry germplasm. Secondly, analyze the key gene nodes and their transcriptional regulatory networks in the anthocyanin biosynthesis pathway, and clarify the genetic mechanisms influencing anthocyanin accumulation. Then, through genetic mapping and genome-wide association analysis, the genetic loci that mainly control anthocyanin content are identified, and molecular markers are developed. Finally, explore the breeding practice paths of high-anthocyanin blueberries, including parental combination design, hybrid population improvement, multi-environment experimental evaluation, and standardized detection of anthocyanin quality, and look forward to future directions such as precise breeding and data platform construction. This research provides theoretical basis and technical support for the high-quality breeding and industrial development of blueberries.
