小麦育种中中间育种材料的改良与创新

The Importance of Studying and Improving Middle Materials in Wheat Breeding

结合从事小麦育种工作多年的经验体会,本文从矮败核不育材料的利用和改良以及控制大粒、大穗、抗白粉病基因的重组创新两方面,系统阐述了小麦育种须走育种先育材料的路子,没有突破性的中间育种材料,就不可能选育出有突破性的新品种,指出现阶段小麦育种工作中改良创新中间育种材料的重要性。

According to wheat breeders' experiences, the paper explained the importance of selecting Bridge materials. Wheat breeding generally deperds on two aspects, one is dwarf male - sterile wheat improvement and enhancement in agronomic characteristics and high quality, the other is pyramiding the genes of controlling big grain, big spike, powdery mildew and other diseases resistance.
