| 摘 要： | 对江西省23个早稻主栽品种(组合)进行了苗期耐冷性鉴定。结果显示:金优L2、潭两优83、T优898、五丰优623、I优899、五优157、荣优1506、淦鑫206具有较强的苗期耐冷性;株两优505、中嘉早17、嘉育948、优I402则表现出极弱的苗期耐冷性;杂交稻组合通常具有比常规稻品种更强的苗期耐冷性;耐冷性基因具有加性及不完全显性效应。

| Abstract: | Twenty - three early rice varieties （combinations） mainly cultivated in Jiangxi province were identified for cold tol- erance at seedling stage under controllable conditions. The results showed that eight early rice varieties （Jinyou L2, Tanliangyou 83, T You 898, Wufengyou 623, I You 899, Wuyou 157, Rongyou 1506 and Ganxin 206） had comparatively stronger cold toler- ance at seedling stage, while the cold tolerance of Zhuliangyou 505, Zhongjiazao 17, Jiayu 948 and You 1 402 was extremely wea- ker. Generally, hybrid rice combinations had stronger seedling- stage cold tolerance ＇than conventional rice varieties. Ueles for cold tolerance showed additive and incompletely dominant effects. |
