Abstract:
The length of dormancy and sprouting characteristics of ten cultivars (Bison, Kennebec, Norchip, Norgold Russet, Norland, Red Pontiac, Russet Burbank, Viking, Dakchip, and ND8891-3), were compared. Russet Burbank had the longest dormancy period and the slowest rate of sprouting after dormancy ended. Viking and Norgold Russet had the most sprouts and Kennebec the fewest. Dakchip had the shortest dormancy period, the greatest weight of sprouts and the greatest weight loss. Dormancy was shortest in the warmest (20°C) storage. Storage at 2°C for six to nine weeks increased sprouting after dormancy ended compared with continuous 10 or 20°C storage.
