引种是解决品种匮乏的主要途径之一，1996年至1998年河南省农科院烟草研究所对引进美国8个烤烟品种进行了隔离种植及产、质、抗病性和生态适应性试验。试验结果，RG17、RG11、K346三品种产、质及抗病性均优于主栽种NC89，可在河南大面积推广种植，K358、V116二品种耐旱性较强，可在豫西山岗丘陵烟区扩大试种种植，K730适应性及抗病能力较差，应继续进行观察。NC27NF、NC37NF二品种叶数较多是多叶型，身份薄，可用来生产优质填充型原料。
Introduction is one of the main ways to solve the variety shortage. From 1996 to 1998, the Tobacco Research Institute of Henan Academy of Agricultural Sciences conducted isolation planting, yield, quality, disease resistance and ecological adaptability test for the introduction of 8 varieties of tobacco in the United States. The results showed that the yield, quality and disease resistance of three varieties of RG17, RG11 and K346 were better than that of main planting NC89, which could be popularized widely in Henan. The drought tolerance of two varieties of K358 and V116 was stronger, District to expand planting, K730 adaptability and disease resistance is poor, should continue to be observed. NC27NF, NC37NF two varieties of leaves is more leafy, thin identity, can be used to produce high-quality filling of raw materials.
