摘　　要：该研究筛选适宜四川宜宾烟区种植的优质烤烟品种,为新品种的储备和推广应用提供科学依据。以云烟87为对照,分析比较了烤烟新品种(系)云烟121、湘烟7号、中川208、SC3262的生育期、农艺性状、抗病性、经济性状、烟叶质量等差异,并利用灰色关联度进行综合评价。结果表明,SC3262、湘烟7号的生育期稍长,湘烟7号的有效叶片数较多,SC3262的叶片较为宽大,中川208对烟草病毒病抗性较好,湘烟7号对烟草根茎类病害抗性较好,湘烟7号、SC3262的产量、产值较高,湘烟7号综合质量较好。灰色关联度结果表明,湘烟7号综合性状表现最好,其次是中川208,适宜在宜宾烟区种植,可进一步示范验证,并进行栽培技术研究。This study screened high-quality flue-cured tobacco varieties suitable for planting in Yibin tobacco area of Sichuan Province,and provided a scientific basis for the reserve,promotion and application of new varieties.Taking Yunyan 87 as the control,the differences in growth period,agronomic traits,disease resistance,economic traits and tobacco leaf quality of new flue-cured tobacco varieties(lines)Yunyan 121,Xiangyan 7,Zhongchuan 208 and SC3262 were analyzed and compared,and the grey correlation degree was used to conduct a comprehensive evaluation.The results showed that the growth period of SC3262 and Xiangyan 7 was slightly longer,the effective leaf number of Xiangyan 7 was more,the leaves of SC3262 were broader,Zhongchuan 208 had better resistance to tobacco virus diseases,Xiangyan 7 had better resistance to tobacco rhizome diseases,Xiangyan 7 and SC3262 had higher yield and output value,and Xiangyan 7 had better comprehensive quality.The results of grey correlation degree showed that Xiangyan 7 had the best comprehensive trait,followed by Zhongchuan 208,which was suitable for planting in Yibin tobacco area,which could be further demonstrated and verified,and the cultivation technology research should be carried out.
