Selection of Rice Cultivars Adaptable to Top Rice Cultivation Region in Southern Part of Korea

The experiment was carried out to select the rice cultivar adaptable to Top Rice cultivation region from 2006 to 2007 in Useong and Kyeongju, Korea. Four cultivars, recommended for high rice grain quality, were cultivated in the different region in this study. The average yield of head rice was higher in Samguangbyeo than the other three cultivars. The protein content was inversely associated with palatability (Toyo value). The protein content of Samguangbyeo was 6.2%, which was the lowest among the tested cultivars. L values in color of rice and cooked rice were not significantly different. The hardness of Samguangbyeo was lower than that of the other cultivars in texture properties of boiled rice on 4 cultivars. In conclusion,considering the rice yield and grain qualities, Samguangbyeo was selected as promising rice cultivar for Top Rice cultivation region.
