灰色关联度分析法在夏绿豆区域试验品种评价中的应用

Application of the Grey Correlative Degree Analysis in Comprehensive Evaluation for Mungbean Varieties of Regional Trial

应用灰色关联度分析法对2006-2008年国家夏播绿豆区域试验10个参试品种(系)的9项主要指标进行了综合分析,结果表明,XLD09与参考品种的加权关联度最大(0.8136),综合表现最优,XLD03次之(0.7943)。该结果与品种实际表现一致。灰色关联度分析法简便易行,可作为传统评价区试品种的一种补充方法,推广应用于国家小宗粮豆区域试验中。

The grey correlative degree analysis was conducted to comprehensively evaluae nine key indicators of 10 tested mungbean varieties in regional trial in 2006-2008.The results showed that XLD09 had the largest weighted correlative degree（0.8136） and the most synthesizing characters with the reference variety;XLD03 ranked the second place（0.7943）,which was consistent with actual performance of the varieties.Since the simplicity of the grey correlative degree analysis methods,it could widely used as a complement to traditional evaluation methods,in the evaluation of minor grain crops varieties in regional trials.
