Evaluation location: Wisconsin, United States
Virus free in vitro clonal cultivar stocks were obtained from the US Potato Genebank collection and three plants each were transplanted in two replicated field plots at Sturgeon Bay, Wisconsin in 2009. Representative tubers were washed, peeled, chopped and weighed for a sample of about 250 gm fresh weight, then air dried at about 50C to stasis and weighed again for calculation of the dry matter percent statistic.
