最近几年,在小麦育种工作中,广泛采用不同发育类型间的杂交。育种家试图藉助这种方法把冬小麦(千粒重高,抗倒伏等)和春小麦(结实性高,对某些病害免疫性强等)的优点结合在杂种中。目前对这种杂种群体中的大多数数量性状和质量性状形成的生理学方面的研究还远远不够。直到现在还没有关于在人工 In recent years, hybridization among different developmental types has been widely adopted in wheat breeding. Breeders attempt to incorporate the advantages of winter wheat (high grain weight, lodging resistance, etc.) and spring wheat (high seedability, immunity to certain diseases, etc.) in hybrids by this method. At present, the physiological studies on the formation of most quantitative traits and quality traits in this hybrid population are far from enough. Until now there was no information about labor
