| 摘 要： | 将38个粳型恢复系在海拔2200 m的昆明市西山区团结镇田间自然条件下种植,全生育期间用自然山泉水灌溉,以当地主栽水稻品种滇系16号作对照进行分析,鉴定其耐冷性(抗寒性).试验结果表明:参与鉴定的38个粳型恢复系中,耐冷性(抗寒性)极强的恢复系仅有1个,耐冷性(抗寒性)强的恢复系有11个,说明现有的粳型恢复系的耐冷性(抗寒性)十分匮乏；粳型恢复系的耐寒性(抗寒性)与空秕率之间呈明显负相关关系,提高恢复系的耐冷性(抗寒性),应降低空秕率.

| Abstract: | 38 restorer lines of Japonica rice were plant at 2 200 meters altitude of Kunming unity xishan under natural condition,and irrigated with natural water all of the growing period,and with Yunnan local rice variety dianxi No.16 as the control to analyse the cold tolerance.The results showed that: in the 38 restorer lines of Japonica rice,only one combination had very strong cold tolerance(cold resistance),and 11 restorer lines with relative strong cold tolerance(cold resistance).The result indicated that Japo... |
