In 2000, we replaced paddy rice cultivar 'Goropikari' with 'Asahi-no-yume' in Tomo Area of Gunma Prefecture. However, we lacked data about suitable harvesting time. Therefore, we examined the suitable harvesitng time for 'Asahi-no-yume' cultured in early and normal seasons for 3 years from 2001 to 2003. The highest yield and quality were obtained by harvesting when the accumulated temperature was 950 deg C and the green-paddy rate was 13% in early planting, and when the former was 1000 deg C and the latter 22% in normal season culture. The paddy water content was about 25% at these times, which was suitable for combine harvesting.
