Comments
Variety, seed grower, and source (state) is provided solely by the seed receiver. We transfer that information to this book.
Plants were VISUALLY read, unless otherwise indicated.
Flags with the number 1: indicates the seed lot was read prior to June 21.
Flags with the number 2: indicates the seed lot was read on June 21.
MOSAIC does not necessarily mean the plant has PVY; rather, it is expressing symptoms that are commonly associated with PVY infection.
10+ indicates more than 10 plants in particular seed lot were affected within a specific category. In seed lots with 10+ infected plants, NOT ALL PLANTS WERE FLAGGED when displaying symptoms.
