Technical Abstract: Potato starch is composed of approximately 75% amylopectin and 25% amylose. We are interested in breeding for higher amylose content, which would increase the fiber content of potato and decrease glycemic index. In order to make progress in a breeding program, we have developed a high throughput assay for amylose. This has allowed us to screen large populations for individuals with high amylose in tuber starch.
