Proposing the similarity measures formula between Vague sets E and G. Concluding Vague resistance analysis. The concrete application steps were:①Establishing comprehensive characters set; ②Screening excellent varieties set; ③Extracting theory optimal varieties set; ④The single-value date transformed into Vague date, obtaining different varieties Vague sets; ⑤Vague resistance analysis 1,the similarity measures were calculated between the excellent varieties Vague sets and the theory optimal varieties Vague sets, obtaining more suitable for people’s needs varieties among excellent varieties; ⑥Vague resistance analysis 2, the weighted similarity measures were calculated between the excellent varieties Vague sets and the theory optimal varieties Vague sets, obtaining more suitable for people’s needs resistance varieties among excellent varieties. According to specific needs of the problem, selecting and applying the steps ⑤ or ⑥. Vague resistance analysis was applied to strawberry varieties resistance analysis, the analysis result was satisfactory. The similarity measures formula between Vague sets E and G was the application basis of Vague resistance analysis.
