摘要

Pea Early-Browning Virus (PEBV) and Pea Seed-borne Mosaic Virus (PSbMV) are seed-transmissible viruses of the pea, and therefore the detection of these viruses in pea seeds is an important tool in control strategies. The enzyme-linked immunosorbent assay (ELISA) is widely used for the detection of plant viruses (Clark and Adams, 1977), and ELISA methods have been described for the detection of PEBV and PSbMV (Hamilton and Nichols, 1978; Van Vuurde and Maat, 1985, Maury et al., 1987). The test methoddescribed here was designed using this information and twenty years of laboratory experience, and evaluated in a comparative test. The method, using ground seed and a DAS-ELISA, can be used to simultaneously detect PSbMV and PEBV in a single extract. Note that the extract is tested in two microtitre plates, one for PEBV and one for PSbMV. The theoretical detection limit is one seed in 100. To ensure a 95% probability that infestations of 0.15% or higher are detected, it is necessary to test 20 subsamples of 100 seeds.
