通过对改革开放 2 0年育成的 7个徐州系列小麦品种进行系谱分析 ,探讨了其中的有关规律 ,初步摸索出超高产育种方法 :育种目标始终以高产为核心。正确处理产量性状间的关系是前提。选配好亲本是关键。选准骨干亲本 ,进行冬春杂交 ,阶梯式杂交 ,亲本之一要具有较好的丰产性 ,大穗多粒或抗病、中矮秆、成穗数较多 ,优缺点能互补。品种资源是基础。试验质量是根本。精细选择是保证。
Through the pedigree analysis of seven varieties of Xuzhou wheat series bred in the reform and opening up in 20 years, the relevant laws were explored and the method of super-high-yielding breeding was tentatively explored: breeding target always center on high yield. Correct handling of the relationship between yield traits is a precondition. Matching a good parent is the key. Select the backbone of the parents, winter and spring cross, step hybrid, one of the parents to have good yield, large ears and more grain or disease resistance, dwarf, spike number more, the advantages and disadvantages can complement each other. Variety resources is the foundation. Test quality is fundamental. Fine choice is guaranteed.
