In 2018, the United States Department of Agriculture (USDA-ARS), the Clemson University, and the University of California jointly announced 40 new varieties of blueberry, including 12 varieties of northern highbush blueberry, 21 varieties of southern highbush blueberry, and 7 varieties of ornamental blueberry. Based on the analysis of the comprehensive characteristics of the announced blueberry varieties, this paper summarizes the current development trend of global blueberry breeding. The results have been shown that: 1) the cultivation of southern highbush blueberry is still the main direction of blueberry breeding, and the number of new ornamental blueberry varieties has increased. 2) The main breeding direction for northern highbush blueberry is to cultivate new varieties with early maturity, large fruit, hard texture, and good storability. 3) The breeding trend of blueberries in the southern highbush blueberry is mainly focused on cultivating new cultivars with the low chilling requirement and have comprehensive characteristics such as early maturity, large fruit, and good fruit quality. 4) The main direction of ornamental blueberry breeding is to pay attention to the diversification of fruit color and the leaf color that changes with the season for use in Garden potted plants and landscaping. 5) In recent years, China has made rapid progress in blueberry breeding except for the traditional breeding countries such as Europe and America. The breeding trend described in this paper will point out the direction for blueberry breeding in China in the future and have important practical reference value.
