摘　　要：以2003年黑龙江省第六区区域试验的12个参试组合(含对照)为研究材料,运用灰色系统理论中杂交组合灰色评判原理与方法,对影响玉米产量的10个性状进行灰色关联分析,结果表明:各主要数量性状对黑龙江省中早熟玉米产量的关联度大小为叶片数、穗位高、秃尖、穗长、出籽率、穗粗、穗行数、株高、行粒数、百粒重。Twelve combinations (including the consrative group) of the sixth regional test of HeiLongJiang Province in 2003 were analysed by using the principle and mothed of grey comprehensive evalution and employed grey relativity analysis on several characters that affect the maize yield. The result shows the magnitude on effects of vary characters on the yield of immature maize in turn was leaf number, ear high, bald, ear length, kernel production ability, ear thickness, rows per ear, plant height, kernel per row, 100-grain weight.
