The experimental results showed that Guiyan 2 had moderate growth duration after transplant, strong field growing power, good uniformity and good agronomic traits; moreover, its yield,production value and rate of first-class tobacco were respectively higher than these of CK by 349.2 kg/hm^2, 4746.3 yuan/hm^2 and 6%, while its average price and grade index were respectively lower than these of CK by 1.13 yuan/kg and 0.06;Guiyan 2 also had the advantages of appropriate intrinsic chemical component content and proportion, as well as better curing characteristics, and it got generally better evaluation from tobacco growers, indicating that Guiyan 2 had a better potential to generalize.展开更多
