| 摘 要： | 北方早熟春玉米区是我国重要的玉米生产基地，早春低温冷害是该区域所特有的生态气候条件，是限制本区域玉米产量水平的重要因素之一。将恒温光照培养箱设定为20、11、7℃三种温度梯度，以出苗率和出苗指数为鉴定指标，对60份稳定系逐级鉴定筛选，鉴定出7℃低温条件下耐低温种质2001-F32、FR1454、HR295、LINE KIN060、KN3，为耐冷玉米品种的选育提供种质保障。

| Abstract: | The early spring maize area is an important maize production basement in china, which has distinct eeoclimate condition. The low temperature in earlier spring is one of the most important factors to limit yield of corn in this area. The constant temperature incubate box was used by setting three temperature of 20℃, 11℃, 7℃. 60 inbred lines were identified and selected in different levels, and 2001-F32, FR1454, HR295, LINE KIN060, KN3 are selected and identified as cool-tolerence germplasm under 7℃. It can provided information in increasing the efficiency of corn breeding. |
