大豆结荚习性是一个重要的生态性状。不少大豆科学工作者总结了这方面的群众经验,并给予了充分的重视。研究了它的地理分布,讨论了结荚习性在品种工作中的重要意义,指出了一定的自然条件下产生了相适应的生态型。但是随着生产条件的改变,这种生态型的分布是否应该发生改变,应该在怎样的条件下发生改变,向着什么方向改变,……这都引起了一些科技工作者的注意。因为明确这些问题不仅在理论上,而且对育种目标的确定,以及在其指导下的育种过程将具有重要的意义。本文拟根据自己所见到的,并学习与参考一些有关资料对以上几个问题提出一些认识,请同志们讨论指导。 Soybean pod habit is an important ecological trait. Many soybean scientists have summed up the mass experience in this respect and have given sufficient attention. Studied its geographical distribution, discussed the importance of the pod habit in variety work, and pointed out that under certain natural conditions, the corresponding ecotypes were produced. However, with the change of production conditions, whether this ecological distribution should be changed, under what conditions should be changed, in what direction to change, ... ... which have attracted the attention of some scientists and technologists. Because it is important to clarify these issues not only in theory, but also in determining breeding goals and the breeding process under their guidance. This article is based on what I have seen, and to learn and reference some of the relevant information on some of the issues raised some understanding, please comrades discuss the guidance.
