摘要

Dongxiang wild rice is an ecological type of wild rice that grows at 28°14′ N. To study its cold tolerance, Dongxiang wild rice (Shangtang 3) was compared with three cold tolerantlate season rice varieties, i.e. M112, IR24 (indica), and Jing0298 (japonica), and three cold sensitive indica varieties, i.e. 754, 6226, and D5035 in cold condition at seedling and heading stage.
