Characterization of grain quality of rice germplasm is important for broadening the genetic base for breeding program. In this study, we characterize the grain size and apparent amylose content of ninety eight rice cultivars which collected from Central of Vietnam. The endosperm types of ninety eight Vietnamese rice cultivars were classified as waxy, opaque, white core and translucency, and GBSS level were divided into four groups, including absent, low, intermediate and high. In non-waxy group, the wide variation of apparent amylose content was observed in thirty four rice cultivars. The continuous variation on the apparent amylose content was observed in three respective groups of GBSS. The grain length showed the positive correlation with apparent amylose content while grain width showed negative correlation. The very low amylose class was not found in two regions including Central highland and South coastal central whereas the intermediate amylose class was not detected in the North central region of Vietnam.
