三类特色小麦的育种实践及遗传机理研究

Research on Breeding Practice and Genetic Mechanisms of Three Special Wheat

小麦优质高产是育种工作的终极目标。为提高小麦面粉的营养品位,培育小麦种质新类型,寻求较大幅度突破目前小麦高产水平的新途径,从2002年起,笔者从三方面进行了育种及理论研究。根据水稻、玉米、谷子等禾谷类作物均有数个糯质品种,却唯缺糯质小麦的现状,本研究的要点之一,即是希冀育出品质较好、产量较高的糯小麦品种,拓宽小麦利用范围,填补种质空白;探索糯小麦遗传规律,为育种提供理论基础。

High quality and yield of wheat is the ultimate goal of breeders.To improve the nutritional quality of wheat flour,foster new types of wheat and seek a more substantial breakthrough in the current level of production of wheat in a new way,I have conducted breeding and theory research from three aspects since 2002.According to the fact that rice,maize,millet and other cereal crops have a few waxy varieties,but we don’t find any waxy wheat,one of the points of this study hopes to bring out new waxy wheat with better quality and higher yield to broaden the scope of the use of wheat and fill breeding gaps,explore the inheritance laws of waxy wheat and provide a theoretical basis for breeding.
