以2008年全国烤烟品种区域试验北方区参试品种的主要农艺性状、经济性状、化学成分、抗病性等调查记载数据为基础,应用灰色关联度法对各供试品种(系)的主要性状进行了综合分析。结果表明,灰色关联度法对于烤烟品种性状综合评价应用性较强,较以往的方法更系统、简洁、明了、易于操作;在等权关联度法和加权关联度法的对比分析中,得出加权关联度法结果更接近实际评价,从而说明权重对于灰色关联度法评价区试品种有着很重要的作用。
Based on the data collected from the investigation of the main agronomic traits, economic traits, chemical compositions and disease resistance of the tested cultivars in the Northern Region of the National Tobacco Variety Regional Experiment 2008, the main characters of the tested varieties (lines) Conducted a comprehensive analysis. The results showed that the gray correlation degree method was more applicable to the comprehensive evaluation of the traits of tobacco varieties and was more systematic, concise, clear and easy to operate than the previous methods. In the comparative analysis of the equivalence degree and weighted incidence degree methods, The result of weighted relation degree method is closer to the actual evaluation, which shows that weight has a very important role for the gray correlation degree method to evaluate the regional variety.
