Effect of Yellow-Dwarf on the Yield of Oats1

Yield reduction caused by the barley yellow-dwarf virus in three spring oat varieties and the possible role of time of infection was considered by inoculating plants at the 3-leaf and boot stages of growth. Average infection in the non-inoculated controls and in plants inoculated in the seedling and boot stages was 1.1, 93.8 and 15.6%, respectively. Yield reductions for the three varieties inoculated in the 3-leaf and boot stages, respectively, were: Fayette, 92.5 and 10.1%; Clintland, 94.4 and 21.8%; and Rodney, 75.8 and 15.0%.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
