| 中文摘要: |
| 本文综述了我国北方冬麦区小麦骨干亲本创新的主要成就，并以鲁麦13和鲁麦14及其在育种中的成功应用为例，指出了亲本创新中普遍存在的抗病品种农艺性状差、产量水平低或高产品种抗病性不持久的问题。对于亲本改良过程中高产与综合抗性不易同步提高的难题，应以提升亲本的丰产性能为前提，积聚持久抗病、慢锈（粉）基因和抗旱等性能。 |
| 英文摘要: |
| Main achievements in developing core elite parents in northern China winter wheat region were reviewed in this paper. Taking Lumai 13 and Lumai 14 and their successful application in breeding for example, the common existing problems in parental innovation, such as poor agronomic traits, low yield and disease resistance of high-yield variety, were pointed out. Referring to the problem that high yield and comprehensive resistance do not tend to be synchronously improved during parental improvement process, it was pointed out that enhancing the parental yielding ability should be as a premise, assembling the durable resistance, slow rust (powder) disease genes and drought resistance characters. |
