摘　　要：1998年早季在广东省农业科学院水稻研究所的人工气候箱内对5个不同类型的高产水稻幼苗作耐冷性比较,结果表明两系法杂交稻培矮64s/E32的耐冷性最强,培矮64s/9311次之;两系法杂交稻组合粤杂122和常规水稻品种粤香占、特三矮2号耐冷性稍差。Comparison of cold tolerance in seedlings of five high-yielding rices was made by using phytotron in Rice Research Institute, Guangdong Academy of Agricultural Sciences during early season in 1998. The results exhibited that the two-line hybrid combination Peiai 64s/E32 had greatest cold tolerance and less in descending order Pciai 64s/9311, Yueza 122, and conventional varieties Yucxiangzhan and Tesan'ai 2.
