本文对三个生态试验点25个不同类型品种及两年的试验资料进行了统计分析。结果表明:不同地点春小麦品种的产量差异主要由积温不同所造成。在不同地点的不同品种间的产量差异则表明不同生态型品种有它特定的适应地区,但适应性广的品种确实存在。并根据品种与环境的互作关系提出了不同生态地区进行品种选育的目标性状,为正确制定育种目标进行生态育种提供了理论依据。
In this paper, statistical analysis was made on 25 different types of cultivars and two years of experimental data from three ecological test sites. The results showed that the differences in yield of spring wheat cultivars in different locations were mainly caused by different accumulated temperatures. The differences in yields among the different varieties at different locations indicate that different ecotypes have their own specific adaptation regions, but the more adaptable varieties do exist. According to the interaction between variety and environment, the target traits of breeding in different ecological regions were put forward, which provided the theoretical basis for the correct breeding target breeding.
