育种工作中,认识小麦生长的生态环境,重视适应性的选择是非常重要的。近代高产小麦品种的出现,使适应性的概念有了新的发展。Simmonds(1962)将适应性区分为一般适应性和特殊适应性。一般适应性指品种对一系列的环境条件表现较低的相关反应,因而能够适应较为广泛的地理环境。特殊适应性指品种紧密适应有限的环境条件,对有限环境中的一个因子或多个因子具有最大的相关反应。参照 Simmonds 的观点,我 Breeding work, understanding of the ecological environment of wheat growth, emphasis on adaptability of choice is very important. The emergence of modern high-yielding wheat varieties has brought about a new development of the concept of adaptability. Simmonds (1962) classifies fitness as general and special. Generic adaptability refers to the breed that has a low correlation with a range of environmental conditions and is therefore adaptable to a wider geographic setting. Special adaptability refers to species closely adapted to limited environmental conditions and has the greatest correlation to one or more factors in a limited environment. According to Simmonds’s point of view, I
