Technical Abstract: In the greenhouse the effects of co-infection of selected systemic viruses on PAV strain of (BYDV-PAV) virus titers were evaluated. Four different hosts, Marshall, Michigan Amber, (wheat cultivars), Clintland 64 (oats) and Hudson Barley were used. The cultivars were planted in pots using a randomized complete block design with three replications. In one set of Treatments the plants were inoculated first mechanically with barley strip mosaic (hordeivirus), brome mosaic virus (bromovirus), wheat streak mosaic virus (potyvirus), wheat spindle streak mosaic virus (potyvirus), BYDV-PAV (luteovirus) and then ten days later with BYDV-PAV. In a second set of ueatments the plants were inoculated first with BYDV-PAV and then ten days later with the mechanically transmissible viruses. Ten days after the second inoculations, plants were collected and tested for BYDV-PAV virus titer. The grain yield, kernel weight and tiller number were also analyzed.
