| 摘 要： | 以湖北省 2 0个玉米地方品种的主要农艺性状的田间调查数据的平均值作性状比较、相关系数的分析和聚类分析。结果表明 :穗长、行粒数、百粒重、秃尖长、单株子粒产量受环境影响的变异系数大 ,可利用于杂交和选择育种 ;单株产量与株高、穗长、穗粗、行粒数、百粒重等农艺性状呈极显著正相关 ;2 0个玉米地方品种可分为 3大类 ,一些大类可以进一步划分为若干亚类

| Abstract: | In the paper,20 local varieties of maize from Hubei Province were studied in 10 agronomic traits by cluster analysis and correlation analysis The results showed that ear length,kernels per row,weight of 100 kernels,ear top length,grain weight per plant were influenced significantly by the environment So these traits can be used in cross breeding and selective breeding;grain weight per plant showed significantly positive correlation with plant height,ear length,ear diameter,kernels per row,weight of 100 kernels etc agronomic traits 20 local varieties of maize( Zea mays L )could be divided into 3 groups |

| Keywords: | maize( Zea mays L ) local variety correlation coefficients cluster analysis |
