摘要
通过对吉林省水稻主要推广品种和新育成希望品系的各生育阶段耐冷特性鉴定结果表明：第一，我省目前推广和新育成的品系在水稻生育前期都具有较强的耐冷性，但在低温条件下出穗期明显推迟而且品种间推迟差异显著；第二，水稻孕穗期耐冷性表现较强的品种（系）：上育３９７、吉９４—Ｂ２、通系１０３、长白７号、农大３号、一目惚；第三，中长期低温处理条件下耐冷性表现稍强的品种（系）：上育３９７、吉９４—Ｂ２、一目惚。
The cold resistance of rice at different growillg stage was studied.The results show:1.The varieties and lines used in Jilin province have strong cold resistance at the beginning growing stage,but the heading time has been delated obviously under low timperature,and the delated time is quite different between varieties;2.The varieties or lines which show strong cold resistance at ear premordia stage are as follows:SHANGYU 397、JI94 B2、TONGXI 103、CHANGBAI 7、NONGDA 3、YIMUHU;3.The varietics or lines which show strong cold resistance at middle and late growing stage under low temperature are as follows:SHANGYU 397、JI94 B2、YIMUHU.
