陆地棉数量性状的灰色关联分析

The Application of Grey Related Analysis to Quantitative Characters in upland Cotton

本文采用灰色系统分析理论中的灰色关联分析法对陆地棉数量及其组成成分、棉子品质和纤维品质三组经济性状进行了灰色关联分析。结果表明,灰色关联度值给出的结果同数理统计中的简单相关结果基本一致。前者对后者的优越之处是所需样本容量不必过大且计算简便。同时本文讨论了灰色关联分析研究数量性状间关系的重要意义。

This article has dealt With the application of ∞ ray related analysis in grey system theory to studying the character relationships, such as the corresponding relationships between seedcotton yield and its constitutive factors, fiber qualities and cotton-seed biochamical characters etc. The results of experiment, show that the application of grey related analysis to quantitative characters in cotton is practicable and basically approachs those of simple correlation method in abiostasties, Meanwhile, the grey related analysis has also some dvantagesy it is not only simple and convenient in calculation, but can be carried out with low sample contents. The important significance of this method in studying the relationships between the quantitative traits in upland cotton was also discussed
