| Abstract: | The comprehensive comparison on the many characters of high generation＇s stable varieties in the regional test of flue-cured tobacco new varieties was conducted by using DIOPSIS and grey relation analysis methods.The results showed that two comprehensive evaluation methods had similar results,which conformed to the reality basically,according to the comprehensive consideration of the economic traits,resistance and quality indexes of flue-cured tobacco;but the difference among varieties obtained by DIOPSIS method was more obvious than that obtained by grey relation analysis method,so DIOPSIS method had better effect of evaluating the advantage and disadvantage of varieties. |
