The growth stage, agronomic trails, stress resistance and economic traits, external qualities of for eight flue-cured tobacco cultivars (Yunyan203, Yunyan99, Yunyan97, Yunyan87, NC102, KRK26, PVH19, and Hongda) were comparatively studied at Zhaoyang county, Yunnan province in 2010. The results showed that agronomic traits of PVH19 were equal to that of K326 (CK) , and the other cultivars' agronomic traits were better than that of K326. NC102 and PVH19 had strong resistance. The economic traits of Yunyan series and NC102 were better than that of K326, while Hongda, KRK26 and PVH19' were worse than that of K326. In general, Yunyan series and NC102 were suitable cultivars at Zhaoyang County.%2010年对昭通市昭阳区种植的云烟203、云烟99、云烟97、云烟87、红大、KRK26、NC102和PVH19的生育期、农艺性状、抗逆性、经济性状等进行综合比较研究,以K326作为对照品种.结果表明,PVH19农艺性状与K326相当,其他品种农艺性状均优于K326；NC102和PVH19的综合抗逆性较好；云烟系列和NC102品种经济性状显著优于K326,红大、KRK26和PVH19经济性状显著低于K326;云烟系列和NC102综合表现较优.
