花生产量与主要农艺性状之间的灰色关联度分析

摘要

The relationship between the yield and 9 major agronomic traits of 13 peanut varieties was analyzed with gray correlationanalysis.The results indicated that the major agronomic traits which had influences on the yield had the following order:100-pod weight>100-kernel weight>left number on main stem>lateral branch length>main stem height>bearing branch number per plant>branch number per plant>pod number per plant>plump pod number per plant. Therefore 100-pod weight and 100-kernel weight had the main influence on the yield of peanut,while pod number per plant and plump pod number per plant had the least influence on the yield.%　　为了探讨花生各主要农艺性状对产量影响的主次关系，应用灰色系统理论的关联度分析法研究了13个花生品种产量与9个主要农艺性状之间的关系。结果表明：影响花生产量的主要农艺性状的排列顺序为：百仁重＞百果重＞主茎叶数＞侧枝长＞主茎高＞单株结果枝数＞总分枝数＞单株结果数＞饱果数。因此百仁重及百果重对花生产量的影响最大，单株结果数及饱果数对花生产量的影响最小。
