Abstract
A survey of viruses on capsicum plants in the Czech Republic was carried out in the years 2006-2010. Altogether, 375 leaf samples with symptoms suggesting viral infection were collected both from open fields and greenhouses. These samples were examined for the presence of Alfalfa mosaic virus (AMV), Broad bean wilt virus-1 (BBWV-1), Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV), Potato virus Y (PVY), Tobacco mosaic virus (TMV) and Tomato spotted wilt virus (TSWV) by ELISA. Viruses detected in the samples were AMV, BBWV-1, CMV and PVY. The most prevalent were CMV and PVY which were present in 24 and 29% of tested samples, respectively. In some cases a complex infection of two viruses was detected. Gene sources of resistance against CMV and PVY are mentioned. The relation of virus occurrence on aphid incidence is discussed.

Abstract
The quarantine processing of 524 broad bean (Vicia faba L.) germplasm accessions from International Center for Agricultural Research in the Dry Areas (ICARDA), Syria (512), Eritrea (8), Iraq (1) and Spain (3) revealed the presence of Alfalfa mosaic virus (AMV) from Spain; Broad bean stain virus (BBSV) and Broad bean wilt virus (BBWV) from ICARDA, Syria; Bean yellow mosaic virus (BYMV) and Pea seed-borne mosaic virus (PSbMV) from Spain and ICARDA, Syria on the basis of visual inspection, growing-on test, electron microscopy and enzyme-linked immunosorbent assay. Seeds were harvested from virus-free plants and released to the indenters which eliminated the risk of introduction of BBSV not reported from India and PSbMV not known to occur on V. faba in India, known to cause significant yield losses.
