1 52 nd ANNUAL WA COMMERCIAL SEED LOT TRIAL June 25, 2015 Cooperators: WASHINGTON STATE UNIVERSITY Departments of Horticulture, Plant Pathology & Cooperative Extension WASHINGTON STATE POTATO COMMISSION WASHINGTON STATE POTATO FOUNDATION WASHINGTON STATE DEPARTMENT OF AGRICULTURE KEY TO FLAGS LEAFROLL: BLACKLEG: MOSAIC: Orange Flag Red Flag Yellow Flag (see description below in comment section) WHITE FLAGS (code to abbreviations) Cal: Calico Chem/Herb: Seed-borne herbicide/chemical damage PLO: Phytoplasma such as Witches broom, Haywire, Purple Top, BLTVA VM, OT, OV: Variety Mix, Off-Type, Off-Type Variety Comments: Variety, seed grower, and source (state) is provided solely by the seed receiver. We transfer that information to this book and save the original tags. Please contact Mark Pavek with any concerns or changes. There should be a plant every inches. Exceptions: seed tubers too large for planter, or plant did not emerge. You may dig for seed pieces. Plants were VISUALLY read, unless otherwise indicated. MOSAIC does not necessarily mean the plant has PVY; rather, it is expressing symptoms that are commonly associated with PVY infection. It is likely, however, that those plants flagged with mosaic flags are infected with PVY. Moreover, PVY was confirmed in some flagged plants via an in-field test kit. NOTE: ALL PLANTS expressing visible symptoms were flagged (in the past, we never flagged more than 10 infected plants; the seed lot was recorded as having Many ). Additional copies may be obtained from the Washington State Potato Commission, 108 Interlake RD, Moses Lake, WA 98837, (509) ; or from Dr. Mark Pavek, Washington State University, PO Box , Pullman, WA (509) Electronic copies will also be available at potatoes.wsu.edu.
