作物育种学属于应用科学,因此,要结合实际正确地综合运用有关的生物学理论,才能有预见地、多快好省地选育作物优良品种,适应农业现代化的要求。杂交育种是现在小麦育种中普遍采用的主要育种方法,但是,由于各种原因,预见性还不高,效果还不大,其中涉及到一些理论和方法问题,人们的看法还有这样那样的分歧。这里,围绕着小麦杂交育种的基本理论、育种目标、亲本选配、杂种后代选育,探讨一些问题。一、小麦杂交育种的基本理论问题现代的作物育种学,就其基本理论体系来讲,是一门人工进化的科学。生物进化论
Crop breeding is a science of applied science. Therefore, in combination with the actual and correct application of relevant biological theories, we can select the fine varieties of crops in a predictable, faster, better and more economical manner to meet the requirements of agricultural modernization. Hybrid breeding is now the main breeding method commonly used in wheat breeding. However, due to various reasons, the predictability is not high and the effect is not great. There are some theoretical and methodological issues involved, and people think that there is such a difference . Here, around the basic theory of wheat hybrid breeding, breeding objectives, parental matching, hybrid offspring breeding, to explore some issues. First, the basic theory of wheat hybrid breeding The modern crop breeding, in terms of its basic theoretical system, is a human evolutionary science. Biological evolution
