Kunmingxiaobaigu (indica rice) and Dalizaoxian (japonica rice), and their F2, F3, F4, F5 and F6 generations with strong cold tolerance, were planted during 1997-99 in 3 rice growing regions in China. The regions included a highland japonica rice growing region at Kunming (Yunnan), a mixed growing region of indica and japonica rice at Yuxi (Yunnan), and a winter indica rice growing region at Sanya (Hainan).
