本文依据“高产、优质、高效”农业发展方针，对生产上种植的克字号小麦通过系谱跟踪，揭示了克字号小麦不同生态类型高产、优质、多抗新品种选育的规律。据此，作者认为：①采用多亲多次的阶梯式复合杂交是春小麦生态育种中进行多抗性新品种选育的主要途径；②采用搭梯上楼、步步攀高的方法，选育突破性的品种；③小麦品种多抗性是稳产的重要保证；④以常规育种为主、多种途径相结合，组建不同生态类型的动态基因库，加强种质资源研究，不断提高育种水平。
Based on the principle of “high yield, high quality and high efficiency” in agricultural development, this paper revealed the law of breeding high yielding, high quality and multi-resistant varieties of K-shaped wheat with different ecological types through pedigree tracking. Based on this, the author believes that: ① using multi-step multi-step hybrid crossbreed breeding of spring wheat is the main way to breed new varieties of resistance; ② using the ladder upstairs, step by step climbing the breeding selection breakthrough Sexual varieties; ③ multi-resistant wheat varieties is an important guarantee of stable yield; ④ to conventional breeding, a combination of ways, the formation of different ecological types of dynamic gene pool, strengthen germplasm research and continuously improve the breeding level.
