摘　　要：柑橘病毒类病害是由病毒、类病毒引起的严重危害世界柑橘产业的病害。随着柑橘产业的发展,新的柑橘病毒类病害不断出现,柑橘病毒类病害的危害也日趋严重。笔者对柑橘黄脉病、柑橘褪绿矮缩病、柑橘叶斑驳病、柑橘树皮裂纹类病毒、柑橘类病毒V和柑橘类病毒VI 6种我国近年来新发柑橘病毒类病害的发生分布、生物学特性和分子生物学特性进行总结,并对新发柑橘病毒类病害的检测和防治方法进行阐述,以期为我国柑橘产业的健康可持续发展提供借鉴。Citrus is one of the most popular fruit crops of the world from the equator to 41 degrees of latitude north and south. As a perennial plant, citrus is high value crop which is infected by a big number of viruses and viroids in the field due to vegetative propagation and grafting. Some of these pathogens cause severe crop losses and often reduce the productive life of the orchards. The most important cause for the worldwide spread and accumulation of viruses and viroids has been the international trading of infected nursery plant material. Subsequently, vector transmission might occasionally play a role in the spreading of these agents at the local level. In China, citrus was infected by more than 20 virus and viroids diseases, including Citrus tristeza, Citrus tatter leaf, Citrus satsuma dwarf, and Citrus exocortis etc, which severely affect its production as well as the quality. During recent years, there has been significant increase in the citrus production in China, and the citrus production of China stayed stably ca 33 million tonnes, which is of economical importance to farmers in the southern part. With the development of new detecting techniques, especially the next-generation sequencing, three new citrus virus and three viroids diseases were identified in China. These diseases are becoming more harmful to citrus production. Progress in studies on the new citrus virus and viroids diseases was summarized. The results obtained in recent years are as following： （1） Citrus yellow vein clearing virus （CYVCV）, a member of genus Mandarivirus, family Alphaflexi- viridae, is the causal agent of yellow vein clearing disease. CYVCV was first observed in Ruili, Yunnan province of China in 2009. Now this virus is widely distributed in China. CYVCV infects most citrus species, varieties and hybrids, and lemon （Citrus limon） is most sensitive to CYVCV. CYVCV is transmitted through vegetative propagation of infected buds, scion or rootstocks, and by mechanical inoculations of sap extracts onto herbaceous in
