摘　　要：为了解决品种匮乏问题 ,1999～ 2 0 0 1年对引自美国的 6个烤烟品种进行了比较试验。结果表明 ,各参试品种主要农艺性状遗传稳定 ,抗病性、适应性均较强 ,其中RG 13与新引NC 89品种的产值、均价、上等烟比例及抗病性均超过对照NC 89;ZT 99的产量和钾含量较高 ,是一个高产优质型品种 ;其它 3个品种的性状表现均未超过对照。经方差分析各参试品种间经济性状的差异有些已达到显著水平 ,原烟品质均较好 。The field experiments on 6 flue-cured varieties introduced from America were conducted in 1999-2001. The results showed that: 1) all tested varieties were genetically stabilized in main agronomic characteristics, superior in disease resistance and adaptability; 2) the main agricultural characteristics, such as output value, average price, and resistance to diseases of RG 13 and newly-introduced NC 89 were better than that of NC 89(the control); 3) the yield and K content of ZT 99 were higher, it was a high yield and quality variety; and 4) 3 varieties, RG 8, Va 578 and newly introduced K 326 were not better than the control. The variance analysis indicated that there were significant differences in economic characteristics among some of the tested varieties, and all cured tobacco leaves possessed the satisfied smoking quality and harmonious proportion of chemical constituents.
