小麦新品种（系）的灰色关联度分析

为给小麦新品种(系)的选育和确切评价以及品种审定提供参考依据,应用灰色关联度分析法,对参加2003～2004年度山东省高肥乙组区域试验11个小麦新品种(系)的13个主要性状进行了综合评估.结果表明:依据品种(系)的灰色关联度顺序所进行的综合评估与品种(系)的实际表现是一致的.良星99、954(5)-4、泰山008的加权关联度位列试验前三位,至2006年分别通过山东省农作物品种审定委员会审定,其余品种(系)已先后淘汰.结果表明,与等权关联度相比,加权关联度结果与品种的实际表现更接近.

Grey Correlative Degree Analysis on the New Varieties of Wheat

In order to provide a reference for the selection and breeding, exact evaluation and approvement of new wheat varieties, making use of the grey correlative degree analysis in regional trial from 2003~2004, the grain yield and 12 main characters of 11 new varieties of wheat were evaluated comprehensively. The results showed that the result of evaluation on the order of revelant grade was consistent with the actual performance of the varieties. The three better varieties were liangxing99, 954(5)-4, taishan008. They were approved by Shandong Province Crop Cultivar Examination and Approval Committee in 2004, 2005 and 2006, respectively. We consider that compare with equal weight correlation degree, the results of weighted correlation degree fit better with the fact of varieties.
