STORAGE • Dormancy length about 20 days shorter than Russet Burbank DISEASE RESPONSE • More resistant to the viruses PVY, PLRV, and tuber net necrosis than Russet Burbank and Ranger Russet; but is slightly more susceptible to foliar early blight • Moderate levels of resistance to common scab • Susceptible to powdery scab • Moderately resistant to mop-top virus, with fewer internal defects from the virus than Ranger and Burbank Galena Russet is a medium- to late-maturing variety that is notable for having both high early and full-season yields. It has higher protein content than standard potato varieties Ranger Russet, Russet Burbank and Russet Norkotah, with high vitamin C content similar to Ranger Russet. Galena Russet exhibits cold-sweetening resistance and maintains acceptable reducing sugar concentrations (<0.1 percent fresh weight) and fry color (
