Chapter 4. Red and Purple-Skinned Fresh Market Potato Variety Trial, 20061

C.M. Hutchinson and Doug Gergela2

Table 1. 

General Comments: A goal of the red/purple-skinned fresh market variety trial is to identify a red potato that has better quality and production characteristics than Red LaSoda or LaRouge.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.
