杂交育种是目前农作物育种工作中应用广泛、效果显著的方法。然而,一些育种者在利用这种常规育种方法时,往往出现失误,迟迟育不出新品种。其中一个重要原因,是对杂交育种的阶段、阶段目标及应注意的问题认识不清,不能采取相应措施予以控制。本文拟从分析杂交育种过程中的主要矛盾入手,划分其阶段,理清各阶段及整个过程中应特别注意而又往往被忽略的一些问题,与育种工作者讨论。杂交育种工作的阶段划分杂交育种是按照遗传学原理,利用不同 Hybrid breeding is a widely used and effective method of crop breeding. However, some breeders often make mistakes when using this conventional breeding method, and are late in developing new varieties. One of the important reasons is that the stage of crossbreeding, the stage objectives and the problems to be noticed are not well understood and the corresponding measures can not be taken under control. This paper intends to start with the analysis of the main contradictions in hybrid breeding, divide the stage, clarify some issues that should be paid special attention and often ignored in all stages and the whole process, and discuss with breeding workers. Cross-breeding breeding stage division hybrid breeding is in accordance with the principles of genetics, the use of different
