In order to identify the adaptability of introduced cigar varieties in Bijie City and screen out cigar varieties suitable for cultivation in Bijie tobacco-growing areas.The randomized block experiment method was used to study the performance of main agronomic traits,economic traits,disease resistance,appearance quali-ty and chemical composition of raw tobacco of 11 cigar varieties such as Florida 301 and Ambxe-ma.The re-sults showed that eight varieties such as Yunxue No.1 had a relatively suitable growth period in the field.Florida 301 and Ambxe-ma are resistant to black shank disease.Guixue No.3 and Qingxue 100 are moderate-ly resistant to black shank disease.Yunxue No.2 and Qingxue 100 are moderately resistant to CMV.The ap-pearance quality of tobacco leaves is better for Ambxe-ma,Yunxue No.1 and Qingxue 108.Among the main chemical components,varieties with suitable nicotine content are Yunxue No.2 and Guixue No.3.Varieties with suitable total sugar content are Ambxe-ma and Yunxue No.2.Varieties with suitable chlorine content are Qingxue 103 and Qingxue 108.Varieties with suitable potassium content are Haixue No.1,Ambxe-ma,Qingxue 200 and Yunxue No.2.Varieties with suitable total nitrogen content are Guixue No.1,Florida 301,Haixue No.1 and Qingxue 103.Except for Florida 301,Ambxe-ma,Guixue No.3 and Yunxue No.2,the potassium-chlorine ratio of other varieties is suitable.Generally speaking,the cigar varieties with better per-formance at Jinsha point are Qingxue 200,Ambxe-ma,Qingxue 103 and Yunxue No.1.The cigar varieties with better performance at Qixingguan point are Yunxue No.1,Ambxe-ma,Qingxue 108,Qingxue 100 and Qingxue 103.The cigar varieties with better performance at Weining point are Qingxue 108,Guixue No.3,Qingxue 103,Ambxe-ma and Qingxue 100.Ambxe-ma and Qingxue 103 performed well in Bijie at three points.The research results can provide a reference for screening suitable cultivated varieties in Bijie tobacco-growing areas.
