摘要
本文对3个黄早4改良系新黄4、潘黄4和黄改114的配合力及其对玉米青枯病的抗性进行了研究。结果表明,1)3个改良系在籽粒品质上优于黄早4,但在单株产量、百粒重和穗重上的一般配合力均低于黄早4;2)3个改良系的特殊配合力方差,在较多的性状上高于黄早;3)在对玉米青枯病的抗性上,黄改114的抗性一般配合力显著高于黄早4。
The combining ability and resistance to green leaf blight in threcorn improved lines of Huangzao 4—Xinhuang 4,Panhuang 4 and Huanggaie114 in the study showed:The three improved lines had better kernel qualityand higher specific combining ability variance in a number of characters th-an that of Huangzao 4,but their GCA in grain yield per plant and 100 ke-rnel weight,ear weight was lower.The GCA of resistance to green leaf bl-ight of Huanggai 114 was significantly higher than that of Huangzao 4.
