对内蒙古地区部分玉米种质资源籽粒的品质性状与农艺性状的相关性，品质性状间的相关性以及与农艺性状的结合进行了研究。结果表明：①玉米籽粒的蛋白质含量，粗脂肪含量与单株产量存在着极显著的负相关关系，与生育期存在着极显著的正相关关系；②玉米籽粒的蛋白质含量与粗脂肪含量存在着极显著的正相关关系；③玉米籽粒中的总淀粉含量与单株产量存在着显著正相关关系，与粗蛋白含量存在着显著负相关关系；④通过一定的育种途径可以将高蛋白高产、高蛋白矮杆，高蛋白高油、高油高产、高淀粉高产与矮杆早熟等性状结合。

Correlation and convergence between quality characters andagronomical traits,relationship among quality characters of 35 maize lines were studied.The results are as follows;①Grain protein content,grain fat content were significantly negative correlated with grain yield per plant,and were significantly and positively correlated with plant growth days.②Grain protein Content was significantly and positively Correlated with grain fat content.③Grain Starch content was significantly and positively Correlated with grain yield per plant,and was significantly and negative correlated with grain protein content.④It is possible high pretein content and high grain yield per plant,and low stem,and high oil content,high oil content and high grain yield per plant,high starch content and high grain yield,and low stem,and early mature traits were get together by some breeding methods.
