摘　　要：通过对鲁南经济带主栽种植的21个小麦品种的产量与主要农艺性状作灰色关联度分析,研究分析主要农艺性状对产量的影响。结果表明:鲁南经济带小麦主要农艺性状对产量的关联度大小依次为:全生育期、容重、穗粒数、千粒重、最高总茎数、成穗率、株高、基本苗、有效穗数。In this paper,the effect of main agronomic characters on yield of 21 wheat varieties planted in South Shandong Economic Belt was studied by grey correlation analysis.The results showed that the order of correlation degree of main agronomic traits and yield in South Shandong Economic Belt were whole growth period,unit weight,grain number per spike,1000 grain weight,maximum total stem number,ear rate,plant height,basic seedlings,effective panicle number.
