The results showed that the underground parts of Dongxiang wild rice were able to survive the cold winter at Wuhan. The ratooning seedlings regenerated from the nodes of the underground stems in the next spring. There was no differencebetween the ratooning plants and plants developed from seeds. The overwintering Dongxiangwild rice is a ideal germplasm for improvement of cold tolerance and for development of overwintering variety and hybrid combination of cultivated rice. 东乡野生稻 越冬性 种质资源 Dongxiang wild rice overwintering ability germplasm S511.9 国家自然科学基金,国家教委优秀青年教师基金 1996-02-01 2021-04-01 2
