| 摘 要： | 利用灰色关联分析法,对早熟玉米的产量及其相关性状进行了分析,结果表明,早熟玉米杂交种产量与相关因素的灰色关联度大小顺序依次为:株高R2>生育日数R1>穗粗R5>行粒数R7>轴粗R8>穗长R4>千粒质量R9>出籽率R10>穗行数R6>穗位高R3。进一步明确了各相关性状对产量影响的大小与主次关系。

| Abstract: | The results of analysis on early-matured maize yield and main agronomic traits among different varieties by gray correlative degree has been as follows： the values of the correlation degree between early-matured maize hybrid yield and main agronomic traits among different varieties were sequenced as follows： plant height （R2） 〉 growth duration （RI） 〉 ear wide （Rs） 〉 kernel numbers of row （ R7 ） 〉 axle wide （ Rs ） 〉 ear length （R4） 〉 1 000-kernel weight （Rg） 〉 ear yield rate （R10） 〉 row number of seeds perear（R6） 〉 ear position height（ R3 ）. This sequence indicated the effects of different traits on yields. |
