摘　　要：用不完全双列杂交法对西黄改等9个黄改系和黄早四进行了籽粒产量配合力的改良效果分析。结果表明,供试黄改系间籽粒产量的配合力达到极显著差异,与原黄早四差异甚大。又以西黄改、天4、豫114、H21、籽粒产量配合力的改良效果明显,其配合力效应均为正值,且都高于黄早四自交系。在育种上应重视利用籽粒产量配合力高的黄改系。The improvement effects of the combining ability of grain yield on nine inbred lines (Xihuang gai etc. ), derived from Huang Zaosi Line and Huang Zaosi itself were studied with the method of incomplete diallel crosses. The results indicated that the combining ability of grain yield of the improved lines from Huang Zaosi had sjgncicant difference at p=0. 01 and had significant difference compared with the original Huang Zaosi. The improvement effect of The combining ability of grain yield on Xi Huanggai, Tian4, YU-114 and H21 was obvious and of them all had pesitive values. These lines are better than Huang Zaosi. So great attention should be given to the utilization of the improved lines from Huang Zaosi in breeding.
