不同光温反应特性的春小麦品种产量稳定性分析

Yield Stability Analysis of Spring Wheat Varieties with Different Reactive Characteristics to Photoperiod and Temperature

为探明黑龙江省春小麦光温反应特性与产量稳定性的关系，对本省小麦四种主要光温反应型８个品种（系）进行了产量稳定性综合评价。结果表明：光敏型品种的稳定性好于光钝型品种；温钝型品种的稳定性好于温敏型品种，并指出本省春小麦品种产量的稳定性首先取决于感光性强弱，其次是感温性强弱。四种光温反应型品种产量稳定性强弱顺序依次为：光敏温钝型＞光敏温敏型＞光钝温钝型＞光钝温敏型。

In cider to ascertain the ralationship between reactive characteristics to Photoperiod and temperature and yield stability of spring wheat varieties in Heilongjiang Province,yield Stabilities of 8varieties in 4 main type were evaluated synthetically in this paper. The results showed that the yield stability of photasensitive varietics was better than that of photoinsensitive varieties and temperature insensitive varieties had better stability than temperature - sensetive varieties. In the meantime,it was pointed out that the first decitive factor of the yield stability of spring wheat varieties is sensitive degree of the vaneties to Photoperiod and second decisive factor is the sensitive degree to temperature. The order of yield stability in varieties of 4 type was: Photosensitive and temperature - insensitive type>photasensitive and temperature - sensitive type>phptoinsensitive and temperature - insensitive type>photoinsensitive and temperature - sensitive type.
