| Abstract: | 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. |
