This report summarized the response and difference on rice quality of cultivars crltivated in Hualien area. A total of ten rice varieties were tested. Results indicated that Tainung 67 showed the highest yield in both crops among Japonica rice, whereas Taichung 189 and Tainan 7 only showed better yield in 1st crop. The grain yield were low for three early maturity cultivars. The grain yield of Tainan sen 15 (Indica rice) was also quite high and stable. Cultivar of Kaohsiung 141 and Tainan 7 possessed high milling recovery and good grain appearance. Following are the Taichung 189 and Tainung 67. The results of palatability evaluation on cooked rice indicated that Taichung 189, Kaohsiung 141 tasted good and stable. But the taste was unstable for the cultiver Chiye 1 and Koshihikari due to lodged easily for their tall and weak culms. The results integrated from the experiment we suggested that cultivar Taichung 189 can be cultivated in the 1st crop for replacing Tainung 67 in Hualien area for its superior eating quality and acceptable grain yield, Kaohsiung 141 for 2nd crop, but grain yield was relatively low for it's early maturity.
