研究工作早已证实 ,在普通小麦中存在着可交配性基因及其它影响可交配性的因素 ,决定着与其近缘种属间的可交配性[1] 。但是我们也应看到 ,在普通小麦近缘种属中同样也存在着控制可交配性的基因及其它影响可交配性的因素 ,在一定的情况下 ,同样也影响甚至决定着它们与普通小麦 The research work has already confirmed that there are cross-mating genes in common wheat and other factors that influence the mateability, which determine the inter-species compatibility with its relatives [1]. However, we should also see that there are also some genes that control the mateability and other factors that affect the mateability in common wheat relatives. Under certain circumstances, they also affect or even determine their relationship with common wheat
