This study was intended to provide some basic imformatiom on the variability of milling quality and grain appearance of rice varieties. A total of 10 grain quality characters relating to milling quality and grain appearance were evaluated, under uniform field practices and postharvest handling operations, for 59 rice varieties including japonica (Japan and Taiwan improved varieties) and indica (IRRI, Traditional, and Taiwan improved varieties) types. In general, the mean performance of some characters of japonica type such as brown rice rate, total milled rice rate, headrice rate, brown rice volume weight (0.11), brown rice grain width, brown rice 1,000-grain weight, the occrruence frequency of chalky endosperm and the opaque area of chalky endosperm were better than those of indica type. On the other hand, indica type was characterized by longer grain length and larger length/width ratio. Among japonica rice varieites, the mean values of brown rice rate, total milled rice rate, head rice rate, brown rice volume weight, the occurrence frequency of chalky endosperm and the opaque area of chalky endosperm of Japan varieties were better than those of Taiwan improved variaties. Among indica rice varieties, the mean performance of head rice rate, the occurrence frequency of chalky endosperm and the opaque area of chalky endosperm of Taiwan improved varieties were better than those of IRRI or Traditional varieties.
