Interpretive Summary: Huckleberry Gold is a new potato variety with purple skin and yellow flesh. It is a specialty market variety that has an attractive appearance and is the first purple skinned, yellow fleshed variety to be released from the Pacific Northwest Tri-State Variety Development Program. It has notable disease resistances to PVX, a potato virus that can cause yield reduction and the golden potato cyst nematode, a quarantine pathogen. These resistances are derived from resistance genes that were introgressed from other potato varieties in a traditional breeding program. Its comparison to Yukon Gold in this paper shows that Huckleberry Gold has a smaller size profile and higher antioxidants than Yukon Gold.

Technical Abstract: Huckleberry Gold is a purple skinned, yellow fleshed fresh market cultivar with similar culinary qualities to the market standard Yukon Gold. It has lower specific gravity, sucrose and vitamin C content, but a significantly higher level of antioxidants. Notable disease resistant characteristics are Potato virus X resistance due to the presence of markers for the PVX resistance genes, Nb and Rx1. In addition it also has the H1 gene present which confers resistance to the potato cyst nematode, Globodera rostochiensis, which has been confirmed by bioassay to pathotype Ro1. The size profile of Huckleberry Gold is smaller than Yukon Gold, allowing a better fit into specialty markets geared to smaller size for fresh use. Huckleberry Gold represents the first purple skin, yellow flesh cultivar to come from the Pacific Northwest Tri-State Variety Development program.
