摘　　要：本研究利用相关性分析及灰色关联度分析法,对10个小麦新品种的产量、容重等7个主要性状进行了分析,结果表明:相关性分析结果显示小麦产量性状及容重受水分的影响不同的性状表现不同幅度的减小,灰色关联度结果表明水旱地条件下各性状对单株产量及容重的关联度大小并不一致,各性状对单株产量及容重的关联度大小不同。在沧州地区选择小麦品种时品种的分蘖力和成穗率是首要考虑的条件,穗粒数也要兼顾考虑,小麦籽粒产量及小麦籽粒容重是比较复杂的综合性状,由许多因素相互结合、互相作用。因此,应用灰色关联度分析方法评价性状间的影响程度是客观可行的,可用于今后的育种实践中。This study used correlation analysis and grey correlation analysis to analyze 7 main characters of 10 new wheat varieties,including yield and bulk density.The research showed that the yield traits and bulk density of wheat were affected by water content,and different traits had different degrees of reduction.The results of grey correlation analysis showed that under dry and water land condition,the correlations between the yield traits and the yield per plant and bulk density were not consistent and varied in degrees.According to the analysis,when selecting wheat varieties in Cangzhou,the tillering ability and the rate of spike formation should be the most important factors,and the number of grains per spike should also be taken into consideration.Wheat grain yield and grain bulk density are complex comprehensive characters,which are combined and interacted with many factors.Therefore,it is objective and feasible to evaluate the influence degree among the characters by grey correlation analysis method,which could be used in breeding practice in the future.
