摘    要:运用灰色关联度分析法,对12个玉米杂交组合的14个主要性状间的相互关系进行了研究分析。结果表明:与产量关系密切的是穗长、百粒重、穗粗、行粒数,其次是株高、穗位高度、茎粗、叶面积指数;增加穗长、行粒数、株高、穗位高度、茎粗可以提高蛋白质、脂肪、淀粉、赖氨酸的含量。

关 键 词:玉米  灰色关联度  相互关系  产量性状  品质性状

Abstract:The grey correlative degree analysis was employed to investigate the relationship among 14 characters of 12 combinations of maize hybrids. The results showed that maize yield was closely related to ear length, 100-seed weight, ear width, and kernel numbers per row. Yield was also related to plant height, ear height stem width, and leaf area index(LAI). The increase of ear length, kernel numbers per row, plant height, ear height can improve the content of protein, oil, starch and lysine.
Keywords:maize  character  grey correlative degree
