【 摘 要 】

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°C and the green-paddy rate was 13% in early planting,and when the former was 1000°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.
