菊花褪绿斑驳病最早由Dimock和Geissinger（1969）描述，他们注意到该疾病最初于1967年在一些商业温室中被发现。Dimocket等人（1971）的结论是，由于移植物传播成功，并且没有发现与该疾病相关的致病菌或真菌，因此该疾病具有病毒病因。Romaine和Horst（1975）首次报道了菊花萎黄斑病的类病毒性质。确定CCMV具有与其他类病毒相似的物理特征，但不同之处在于宿主范围非常窄，并且与其他类病毒相比传染性较小。据报道，唯一对CCMV敏感的寄主是菊花（chrysanthemum moriolium）、zawadskiivar.latilobum和c。zawadskiivar.latilobumcv。克拉拉寇蒂斯。为了确定CCMV复制是否支持，对51个品种和栽培品种（包括9个菊花品种和35个属）进行了测试。CCMV对2种菊花有传染性，对11种已知支持其他类病毒RNA复制的植物无传染性。据报道，在丹麦（Paludan， 1980年）、法国（Monsionet al.， 1980年）和印度（Singhet al.， 1978年）感染的菊花中都有CCMV。
The chrysanthemum chlorotic mottle disease was first described by Dimock and Geissinger (1969), who noted that the disease was initially seen in 1967 in a number of commercial greenhouses. Dimocket al. (1971) concluded that the disease had a viral etiology since graft transmission was successful and since no pathogenic bacterium or fungus was found associated with the disease. The viroid nature of chrysanthemum chlorotic mottle was first reported by Romaine and Horst (1975). CCMV was determined to have physical characteristics similar to other viroids but differed by having a very narrow host range and by being less contagious than other viroids. The only hosts reported to be susceptible to CCMV are cultivars ofChrysanthemum morifolium, C.zawadskiivar.latilobum,andC. zawadskiivar.latilobumcv. Clara Curtiss. Fifty-one species and cultivars were tested, including 9 chrysanthemum species and 35 genera, to determine whether CCMV replication was supported. CCMV was infectious to 2 species of chrysanthemum and noninfectious to 11 species of plants known to support RNA replication of other viroids. CCMV has been reported to occur in infected chrysanthemums in Denmark (Paludan, 1980), France (Monsionet al., 1980), and India (Singhet al., 1978).
