摘　　要：对笔者发现的一个Lx9801变异株进行考查。结果表明:Lx9801变异株与Lx9801的差异主要表现在叶鞘、花丝、花药的颜色方面,这些性状可能由同一基因控制;它们在株高、穗位高及单株产量等重要性状上没有明显差别,相互间也没有明显杂种优势;SSR标记分析显示,两个材料的差异与生产上自交系郑58内部差异率相似。表明花青素显色这类性状对产量影响的作用有限。In this study , a variant of maize inbred line Lx 9801 was investigated compared with Lx 9801 . The results showed that the variant was different from Lx 9801 in the colors of leaf sheath , filament and anther , which might be controlled by the same gene .There were no obvious differences in plant height , ear height , yield per plant and etc , and there was no obvious heterosis .SSR analysis showed that the difference rate be-tween the 2 materials was similar to the internal difference rate of inbred line Zhen 58 .These results indicated that the color of organs determined by anthocyanin was not important for yield .
