要搞好冬麦杂交育种工作,必须了解、认识杂交后代的遗传规律。我县许多四级农科网组织近年来都在搞冬麦杂交育种工作,但是普遍存在着一个问题,就是不了解遗传规律,只是利用多组合来达到选择机率高的目的,这就带有很大的盲目性。实际上,组合多,后代株 To do a good job in crossbreeding of winter wheat, we must understand and recognize the genetic laws of the offspring of hybrids. Many county four agricultural network organizations in recent years are engaged in winter wheat cross breeding work, but there is a common problem, that is, do not understand the laws of heredity, but to use multiple combinations to achieve high probability of choice, which is very Big blindness. In fact, the combination of multiple, offspring strains
