摘要
对东乡野生稻的越冬性能进行了连续２年的观察，结果表明：东乡野生稻的稻蔸能在武汉地区安全越冬，翌年春季再生苗从地表以下的茎节长出．越冬再生植株与种子实生植株相比并无差异．
Observation was made for two years on the overwintering ability of Dongxiang wild rice(Oryza rufipogon). 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.
