| 摘要: |
| 1986-1991年在田间对小偃6号小麦的观察表明，前期温度偏低时，（1）反应型与感病品种表现一致，但病情发展缓慢；（2）潜育期比感病品种长；（3）后期当日平均气温上升到18-21℃持续3ｄ以上时，转变为抗病反应；（4）高温抗条锈性对小种无专化性；（5）产量损失不显著。 |

| High-Temperature Resistance of Xiaoyan No. 6 Wheat to Strip Rust |
|

| Abstract: |
| The field observation in 1986～1991 shew that Xiaoyan No.6 wheat has
such characteristies as follows:(l)At early stage with relative lower temperature,its reaction type to the disease is the same as that of the susceptible varieties,but the spreading rate and serious degree of the disease develop slowly;(2)The incubation period is
longer than that of susceptible varieties;(3)At later stage when the day average temperature rises to 18～21℃ for over 3 day,changes from susceptible to resistance;(4)There
is no race-specificity in the high-temperature resistance to strip rust;(5)The loss of
yield is not remarkable. |
