目前我省育种工作者十分重视的问题之一就是如何测定作物的稳产性和适应性。一个优良的推广品种不仅能在有利的环境条件下获得高产,而且在不利的条件下也应有相对的高产,即一定的稳产能力。育种实验证明:许多高产品种,即具有高产特性,又具有适应性广、稳产的能力。众所周知,品种 At present, one of the problems that breeders in our province attach great importance to is how to determine the stability and adaptability of crops. An excellent variety can not only achieve high yield under favorable environmental conditions, but also have relatively high yield under certain unfavorable conditions, that is, certain stable yield capacity. Breeding experiments show that: Many high-yield varieties, that is, with high yield characteristics, but also has a wide adaptability, stable production capacity. As we all know, variety
