Missaukee: A Round White Potato Variety Combining Chip-Processing With Resistance to Late Blight, Verticillium Wilt and Golden Cyst Nematode

Previously identified as breeding line MSJ461-1, Missaukee is a round white chip processing potato variety resulting from a cross between Tollocan and NY88 and has foliar resistance to potato late blight (Phytophthora infestans de Bary). This variety has an attractive round shape and mildly netted, bright skin. Seven years of field testing in Michigan indicate that the yield of total marketable tubers in Missaukee is similar to that of Snowden. However, Missaukee has a lower incidence of internal defects than Snowden. Specific gravity ranged from 1.069 to 1.086 in Michigan trials and out-of-the-field chip scores were similar to those of Snowden. Missaukee showed some resistance to Verticillium wilt in 2-years of trials. DNA marker and greenhouse tests indicate that Missaukee is also resistant to the golden cyst nematode (Globodera rostochiensis Woll) pathotype Ro1.
