Analysis on Transition of Revised Standard of Flue-cured Tobacco Grading

In order to verify the applicability and scientificity of revised standard of flue-cured tobacco grading system, a strategy of grade transition based on the text description in revised standard of flue-cured tobacco was designed, and the number and stalk position of grades were counted before and after transition. The weighted scores of adjacent grades were analyzed with one-way ANOVA. The result indicated that 38 grades were totally transferable to 24 grades of revised standard. The stalk position of grades and grade differences between adjacent grades exhibited more significant than before transition. The revised standard is practicable and easy to learn. Consequently, the revised standard of flue-cured tobacco was applicable, scientific and basically feasible.
