应用灰色系统理论中关联度分析法对12个小麦品种的6个相关因素与产量的关联度分析,结果表明小麦产量与其相关因素的关联度大小顺序为:穗粒数>千粒重>亩穗数>最高分蘖>基本苗>有效分蘖率。与产量密切相关的因素是穗粒数、千粒重、亩穗数等。
Correlation analysis of 6 factors and yield of 12 wheat cultivars by using the method of relevance analysis in gray system theory showed that the order of correlation of wheat yield and its related factors was as follows: grain number per spike> 1000-grain weight> number of ears> The highest tillering> basic seedling> effective tillering rate. The factors closely related to yield are the number of grains per spike, the weight of 1000 grains, the number of ears per mu and so on.
