摘　　要：以灰色系统理论分析方法为基础,利用灰色关联度法对23份玉米杂交种产量及主要农艺性状间的关系进行了研究。结果表明:与产量密切相关的农艺性状依次为生育期、穗长、出子率、株高、百粒重、穗行数和穗位。该方法可为玉米新品种选育提供参考。Based on the theory of grey correlative degree analysis, 23 maize hybrids were analyzed. The results showed that the yield was closely related to growing period, ear length, kernel rate, plant height, 100-seed weight, rows per ear and ear height. This method may provide a reference for the selection and breeding of new maize varieties.
