Commercial potato seed samples are requested from WA Growers for the Washington Seed Lot Trial. Two hundred whole (single drop) seed is an acceptable sample size, or 50 lbs of 4 oz single drop seed.
Requested: minimum of 50 lbs of 2-4 oz whole seed, no seed treatments. We want a representative sample-if applicable, include a representative amount of rotten tubers! (Seed over 6 oz is not acceptable)
A representative sample is needed. Sampling the first (or last) 200 seed from the truck is not likely to provide a representative sample of the lot. Sample tags may be obtained by calling the Potato Commission at 509-765-8845.
Your assistance with collection and drop off of seed samples is needed. Seed samples may be taken to the WSU Othello Research Unit (509-488-3191); located on Booker Road ¼ mile south from State Highway 26 and about five miles east of Othello.
