Chapter 3. White-Skinned Fresh Market Potato Variety Trial, 2006 1
C.M. Hutchinson and Doug Gergela2
General Comments A goal of the white-skinned fresh market variety trial is to identify a round white potato that has better quality and production characteristics than LaChipper. Identification of "specialty" potatoes that expand the marketable varieties produced in Florida is also a priority. Established varieties were included to provide a baseline for the numbered clones.
