摘　　要：[目的]优化毕节市朝天椒栽培品种,筛选适宜毕节市朝天椒种植品种。[方法]利用灰色系统理论对引种毕节种植的13个朝天椒品种果实成熟率、生育期、分枝数、主茎高、主茎粗、果实横径、果长、单株果实数、单株鲜果重量、含水量、干辣总产量、红熟干椒产量、植株抗倒伏率、植株抗病率、果实可溶性糖含量、果实可溶性蛋白含量、果实V C含量、辣椒素含量、二氢辣椒素含量等19个主要指标进行关联度分析。[结果]13个参试品种的加权关联度值比对照“毕节朝天椒”大,占参试品种的28.5%,其中“金娇干6号”加权关联度值和产量排名第一,综合表现最好;“农望指天1号”“艳椒425”2个品种综合表现次之。[结论]“金娇干6号”“艳椒425”“农望指天1号”3个朝天椒品种均适合在毕节种植,“金娇干6号”最适合在毕节市引种种植。[Objective]To optimize the cultivars of Capsicum Chinense in Bijie and select the suitable cultivars for Bijie.[Method]The 19 main indexes of fruit maturity,growth period,branch number,main stem height,main stem diameter,fruit diameter,fruit length,fruit number per plant,fresh fruit weight per plant,water content,total dry pepper yield,yield of red pepper,lodging resistance,disease resistance,soluble sugar content,soluble protein content,V C content,capsaicin content and dihydrocapsaicin content in 13 introduced cultivars were analyzed by using the grey system theory.[Result]The weighted correlation degree of the 13 tested varieties was larger than that of‘Bijie Chaotianjiao’,accounting for 28.5%of the tested varieties.Among them,‘Jinjiaogan 6’ranked first in weighted correlation degree and yield,and had the best comprehensive performance.‘Nongwangzhitian No.1‘and‘Yanjiao 425’had the second comprehensive performance.[Conclusion]‘Jinjiaogan 6’‘Yanjiao 425’and‘Nongwangzhitian No.1’were all suitable for cultivation in Bijie.‘Jinjiaogan 6’was most suitable for introduction and cultivation in Bijie.
