    Abstract:

    Blueberries are renowned worldwide for their unique nutritional and health benefits. However， as cultivation periods extend， blueberry varieties in different countries and regions are facing challenges such as stress susceptibility， poor adaptability， and mismatched chilling requirements. These issues partly stem from excessive inbreeding， leading to limited genetic diversity and inbreeding depression， which restrict the production of high-quality fresh blueberries and the expansion of cultivation areas. Consequently， countries have initiated hybrid breeding programs based on their local climates and market demands. Nevertheless， current blueberry breeding methods remain confined to traditional hybridization techniques， which are time-consumption， resource-intensive， and lack the application of modern biotechnological breeding approaches. This article aims to introduce the countries involved in blueberry breeding and their varietal development processes， while summarizing and analyzing the breeding trends of six major types of blueberries. It also discusses the modern biotechnological approaches applied in current global blueberry breeding and outlines future breeding goals. It is hoped that these insights will provide a theoretical basis for blueberry breeding efforts in our country.
