Applicability of Identical and Different Analysis Method of Improved AHP in Screening Peanut Varieties

In order to quantitatively and objectively screen the introduced peanut varieties in Fujian Province in recent years, based on the data measured by the grey relational analysis method of the screening peanut varieties in Fujian, the comparative analysis was carried out by using the identical and different analysis method by AHP to determine the weight. And the rank correlation analysis was conducted on the obtained results with that of the grey relational analysis method. The results showed that the dominant factors that influenced the effect of introduction were plot yield, lateral branch length, kernel percent and stem length. Jinghua 20 and Xuan 33 were the most suitable varieties to be introduced, with the largest degree of identical discrepancy contrary, moderate plant characters and high overall yield. The rank correlation analysis was carried out between the results of the identical and different analysis method by improving AHP to determine the weight and the results of the grey relational analysis method, and the results showed that the method passed the significance test, indicating that it was applicable in the screening of peanut germplasm resources in Fujian Province.
