| 摘 要： | 为给广适性小麦育种提供借鉴，本文对优质广适性小麦品种西农979的性状进行了解析。小麦品种西农979广适性的遗传基础有两个：一是春性发育特性与匍匐苗相的结合，在发育方面打破了春性与耐寒性的连锁；二是群体调节能力强且综合抗性好，育种上聚合了众多亲本的优良性状。在气候变暖的大趋势下，通过发育调控提早熟期将成为育种取得突破的着力点。

| Abstract: | There are two genetic basis of wide adaptability in Xinong 979. One is that the developmental traits of springness is combined with creeping seedling,and the linkage of springness and cold resistance in development is broken; the other is that,in population,the adjustment ability is strong and comprehensive resistance is well,and many fine traits of parent are synthesized in breeding. With the general trend of climate warming,maturity accelerated by adjusting the growth will become the breakthrough point. |
