Abstract

One of the most important diseases of pea is caused by Pea seed-borne mosaic virus (PSbMV), which has a relatively wide host range. Since there are few varieties with resistance against the virus, and spraying insecticides is not very effective, the determination of the disease and the pathogen in the seeds is very important. Inoculum prepared from pea seeds showing typical virus symptoms caused very mild symptoms on Chenopodium amaranticolor and C. quinoa, but several chlorotic/necrotic lesions on bean (Phaseolus vulgaris) cv. Scarlet, and systemic symptoms with mosaic and curling of top leaves on bean cv. Maxidor. The detection of the virus was carried out by PCR using universal primers and virus sequence analysis. According to the phylogenetic analysis the PSbMV isolate identified in Hungary belongs to the pathotype P1 and associated with the cluster 2 isolates.
匈牙利豌豆花叶病毒首次报道
豌豆花叶病毒(PSbMV)是豌豆最重要的病害之一,其寄主范围较广。由于对病毒具有抗性的品种很少,而且喷洒杀虫剂效果不佳,因此确定种子中的病害和病原体非常重要。从豌豆种子制备的接种物表现出典型的病毒症状,在苋菜和藜麦上引起非常轻微的症状,但在豆科植物(Phaseolus vulgaris)上引起一些萎绿/坏死病变。赤红,及全身性症状,上叶呈镶嵌状和卷曲状。Maxidor。采用通用引物和病毒序列分析进行PCR检测。根据系统发育分析,在匈牙利发现的PSbMV分离物属于P1型,与第2群分离物相关。
