为了适应轮作套种的需要,躲避小麦生长后期的自然灾害,小麦早熟品种日益受到农民重视。目前生产上兼具早熟、高产、抗病等特性的小麦良种较少,而且有些品种适应性差。为了探索培育早熟冬小麦良种的方法和途径,我们对早熟性状的亚性状遗传进行了研究及其对唐山地区自然条件的反应进行了分析研究,简报如下。 In order to adapt to the need of rotation cropping and evade the natural disasters in the latter part of wheat growth, the precocious varieties of wheat are increasingly valued by peasants. At present, there are fewer wheat varieties with the features of early maturity, high yield, disease resistance and the like, and the adaptability of some varieties is poor. In order to explore the methods and ways of cultivating precocious winter wheat varieties, we studied the inheritance of traits of prematurity traits and their responses to the natural conditions in Tangshan.
