Based on a study of 177 samples, rice var. could be tentatively classified into 8 quality types primarily on the basis of total and hot-water-insoluble amylose contents and viscogram pattern. Rice of type I (high total and insoluble amylose) cooked very hard and flaky, while that of type VIII (waxy, negligible amylose) cooked very soft and sticky. Gelatinization temp. (GT) could be indexed by alkali score, water-uptake ratio, or soluble-amylose ratio. Equilibrium moisture attained by rice upon soaking was a combined function of the amylose content, the GT, and kernel chalkiness. The viscogram pattern was largely, but not wholly, a function of the amylose. Protein content was not related to other properties.
