稳产性是每个育种工作者十分关心的问题。一个优良品种不仅要在有利的环境条件下能够高产,在不利的环境条件下也应具有相对高产即稳产的能力。过去一般认为只有产量中等的品种才能稳产,但是育种实践表明许多高产的品种同时也是适应性广从而是稳产的品种。可见高产和稳产这两个性状可以在大体上互相独立,把高产和稳产两者结合起来列为育种目标是可行的。
Stability is a problem that every breeder is very concerned about. An excellent variety should not only be productive under favorable environmental conditions, but also be able to produce a relatively high yield, ie stable yield, under unfavorable environmental conditions. In the past, it was generally believed that only middle-yielding varieties could stabilize, but breeding practices show that many high-yielding varieties are also amenable to stable yield. It can be seen that the two traits of high yield and stable yield can be largely independent of each other. It is feasible to combine both high yield and stable yield as breeding targets.
