First report on Pea seed-borne mosaic virus in Hungary
Acta Phytopathologica et Entomologica Hungarica 55 (2), 161-166
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 impor-tant. Inoculum prepared from pea seeds showing typical virus symptoms caused very mild symptoms on Che-nopodium 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 phy-logenetic analysis the PSbMV isolate identified in Hungary belongs to the pathotype P1 and associated with the cluster 2 isolates.
