Technical Abstract: Because most of the dry matter of potato tubers is starch, an understanding of starch properties is important in potato improvement programs. Starch granule size is considered to influence tuber processing quality parameters such as gelatinization temperature, viscosity, and water holding capacity. Published literature has indicated that starch granule morphology differs among wild relatives of potato. This study was undertaken to characterize differences among wild Solanum species with respect to starch granule properties, including surface area, length, width, shape, and optical interference figures when viewed under polarized light.
