Effects of genotype, environment, and postharvest storage on the total ascorbate content of potato (Solanum tuberosum) tubers.

The total ascorbate content of potato tubers from 33 Solanum tuberosum genotypes grown at three geographically diverse sites in Europe in each of two years was determined immediately postharvest and after approximately 4 months of storage at 4 degrees C. Statistically significant differences in total ascorbate concentration were observed between genotypes both at harvest and after storage. In all genotypes, the levels of ascorbate decreased during storage. These results are discussed in terms of their implications for diet and health as well as in terms of breeding for improved vitamin C content in potatoes.

Progress in improving processing attributes in potato.

The recent publication of a molecular-function map of carbohydrate metabolism and transport in potato enables a candidate-gene approach to be used to solve the problem of cold-sweetening, signifying a significant step in our understanding of this economically important trait. With confirmation of the role that many important enzymes play in starch metabolism and their position on a detailed linkage map, we should now be able to make progress in manipulating this trait, either through conventional means such as marker-assisted selection or through transgenic approaches.
