Abstract:

Over the past five years，China’s citrus industry has maintained a growth trend in both planting area and output，with its production 69.72 million tons，ranking first in the world. The industry has shown gradual shifting from the eastern toward the western regions；Guangxi has become the largest production area，Yunnan has been keeping growth. A total of 69 new cultivars got plant new cultivar protection in China. A number of new varieties have been used in the industry；about 90 cultivars are commercially cultivated with the proportion of late-maturing varieties increasing；the fresh fruit supply has become more evenly distributed throughout the year. Although the proportion of processed products has risen slightly，the pattern dominated by fresh consumption has remained largely unchanged. Modern post-harvest fruit sorting equipment and technologies have been rapidly used in the industry. Considerable progress has been made in omics-based germplasm exploration，with the identification of genes and regulatory modules conferring important traits such as oil glands，fruit color，acidity，and self-compatibility. Also，breakthroughs have been made in basic research on Huanglongbing disease. Future research priorities will focus on meeting market demands for diversified varieties and balanced supply，as well as addressing challenges including aging labors and damage from diseases and pests such as Huanglongbing. Omics，information science，and artificial intelligence will be widely applied in various research and technological development endeavors.
