摘　　要：利用先锋种质LD6006和Lancaster种质(Mo17),及热带种质峰绿5系和8759系,2000-1118系,并单1号父本H02-68系,定性改良选育出广适、稳产自交系H07-20和H07-21系。用H07-20×H07-21组配的杂交组合再分别在代表不同生态条件的绛县、曲沃、寿阳、太原进行种植观察,在4个地区比先玉335增产5.1%～7.7%,比郑单958增产7.94%～10.36%。With the germplasms of Xianfeng LD6006 and Lancaster（Mo17）,as well as Fenglyu 5 lines and 8759 lines,2000-1118 lines,father of Bingdan 1 H02-68 lines H07-20 and H07-21 lines of extensive adaptability,and stable yield were selected.Later,cross group of H07-20 × H07-21 lines were planted in Jiangxian,Quwo,Shouyang counties and Taiyuan where are representives of various ecological environments.The results showed that the yield of the cross group was 5.1%～7.7% and 7.94%～10.3% higher than that of Xianyu 335 and Zhengdan 958 respectively.
