The harvest results are starting to come in from the 2012 OSU Statewide Wheat Variety Testing program. The first results are from the Hermiston Research and Extension Center. These trials are for soft white and hard winter varieties.
There was a severe and uniform infection of barley yellow dwarf virus at the Hermiston site which significantly reduced grain yields, plant height, and maturity.There were some visual differences in the disease expression seen during the Wheat Field Day early this year. While the seed was treated with an insecticide at planting, with a long open fall with significant aphid pressure the seed treatment did not last long enough to prevent infection last fall.
We will be posting the variety trial results on my website OSU CerealCentral as they are available. So be watch for future updates.
