灰色功效函数多维综合评估在甜菜区域化试验中的应用

The Application of Multidimensional Synthetic Evaluation of the Grey Efficacy Function to Sugarbeet Regional Test

简要地介绍了灰色功效函数多维综合评估的原理和方法。对第七届国家甜菜区域试验结果（洮南点）进行评估，结果表明，甜8911最优，对照吉甜301最差。此结果与数理分析的结论基本一致，而且能够明确反映出各参试材料的优劣程度。此方法应用方便，是一种较为理想的区域试验评判方法。

The principle and method of the grey efficacy function multidimensional synthetic evalu ation was described concisely, and the result of the seventh national sugarbeet regional test (Taonan area) is best,Jitian 301 (ck ) is worst. The result is according to the conclusion of mathematical analysis,and can reflect the level of good and bad of every tested variety. So the grey efficacyfunction multidimensional synthetic evaluation is a convenient and ideal judging method of regional test.
