摘　　要：以17个玉米杂交组合为材料,对10个穗部性状和子粒含水量进行相关性分析。结果表明:穗粗、行粒数对子粒含水量呈显著正相关;穗行数、轴粗、出籽率、粒面积、粒深对子粒含水量呈显著的负相关;其它穗部性状对子粒含水量相关性不显著。通过改良穗部性状,可以选育子粒含水量低的杂交种。Correlation analysis was conducted on kernel water content and 10 ear characteristics of maize for 17 maize hybrid lines. Results showed that ear diameter, kernels of row had a significantly positive effect on kernel water content, while rows per ear, cob diameter, grain rate, surface area of kernels and kernel depth had a significantly negative effect on kernel water content, no significant correlation was found between kernel water content and the other 5 ear characteristics that tested in this trial. Hybrids low in kernel water content could be selected by improving certain ear characteristics in breeding process.
