品质和产量同步改良是小麦育种的重要目标。自20世纪70年代开始,本研究利用来自CIM-MYT的优质小麦叶考拉F70(Yecora F70)进行品质育种,先后育成优质面包小麦品系京771和中作8131-1、中优9507、中优206等三个优质强筋小麦新品种,产量水平得到逐步提高。中优206较好地实现了优质和高产的结合。中作8131-1及其衍生系已成为中国小麦品质育种的重要优质源之一。本文系统介绍了YecoraF70及其后代在品质育种中应用的最新进展,目的是为中国小麦品质育种提供方法和经验。
An important objective in wheat breeding is to improve both processing quality and yield potential.Using high quality germplasm Yecora F70 introduced from International Maize and Wheat Improvement Center(CIMMYT),high quality line Jing 771 was developed in 1981,followed by Zhongzuo 8131-1,Zhongyou 9507,and Zhongyou 206,which all maintained good bread-making quality and have been released.The new cultivar Zhongyou 206 combines excellent bread making quality with high grain yield potential.Zhongzuo 8131-1 and its derived lines is one of the quality donors in Chinese wheat quality improvement program.The progress in breeding for bread making quality by utilization of Yecora F70 and its derivaties was review to provide some methods and experiences for Chinese wheat quality improvement.
