Standard Cultivar

Tubers of five summer potato cultivars were monitored weekly for chip color, reducing sugars, sucrose, and marketable yield for 4 wk commencing 3 July, about 80 d after planting, in 1985 and 1986 at Harrow and Simcoe, Ontario. Atlantic and Conestoga tubers generally contained the lowest sugar levels, were the only cultivars to produce acceptable colored chips by 3 July, and had lighter chip color than all cultivars, even lighter than the standard cultivar, Superior. Conestoga yields by 3 July (about 13 t ha−1) exceeded those of Superior (about 10 t ha−1), but Atlantic required 7–10 d more growth to produce comparable yields. Atlantic and especially Conestoga may be more suitable than Superior for use as main summer chipping cultivars in southern Ontario.Key words: Solanum tuberosum L., cultivar, chip color, sugar content, marketable yield, maturity

Cold Induced Sweetening

When stored at temperatures less than 10 °C, tubers of all cultivated potatoes exhibit cold-induced sweetening (CIS) during which starch degrades to sucrose, glucose, and fructose. Upon frying at high temperatures, the reducing sugars (Fru, Glu) interact with free amino acids via the non-enzymatic Maillard reaction to form dark-colored chips that are unacceptable to consumers. In addition, scientists recently discovered that the toxic chemical acrylamide is also produced during frying. Although storage at warmer temperatures reverses CIS and circumvents dark chip production, the probability of storage loss due to shrinkage and disease increases. Wild Solanum species form the backbone of many potato-breeding programs. In this study, we evaluated 36 different plant introductions (PI) including 20 different species, grown in Madison and Rhinelander, Wis., to identify germplasm resistant to CIS for genetic analysis. After storage for 2–3 months at 4 °C, tuber sugar and amino acid content were analyzed via HPLC and slices were fried to determine chip color. Sugar and chipping data support previous research indicating CIS resistance in S. okadae, S. raphanifolium, and S. phujera. Interestingly, some germplasm selections with high reducing sugar content produced light-colored chips, indicating exceptions to the typical correlation between reducing sugar content and chip color. Genetic bases to these exceptions are under evaluation.
