Creator:: Crabtree, Kristine L.
Abstract:: Population size of Clavibacter michiganensis subsp. sepedonicus in potato cv Russet Burbank and plant response as affected by drought were assessed in a greenhouse experiment. Water deficit stress and no stress treatments, and inoculum densities of 0 or 2 X 10⁷ cfu C. m. sepedonicus/seed piece were arranged factorially. Stem...

Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Abstract:: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10...

Creator:: Whitworth, Jonathan L.
Abstract:: Potato leafroll virus (PLRV) causes yield and quality losses in potato. PLRV is identified by plant symptoms and serological tests such as an enzyme-linked immunosorbent assay (ELISA). A similar serological test, direct tissue blotting assay (DTBA), was used to detect and monitor PLRV movement in field-inoculated Russet Burbank plants and...

Creator:: Hane, Dan C.
Abstract:: Virus contamination in a potato breeding program can seriously disrupt the variety development process. Experiments were conducted from 1989 through 1993 to: evaluate the extent to which Potato Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding program, determine viral spread within hills and within individual tubers,...
