Abstract：Three indexes as field population density，number of injured/all and injury index of leaf，were used to evaluate resistance of Bradysia odoriphage of Chinese chive.Systematic clustering analysis was carried on of the resistance to Bradysia odoriphage for 20 Chinese chive varieties.The result showed that there were differences among resistances to Bradysia odoriphage of different varieties.Varieties of‘Yujiu No.1’and‘9-2’had the strongest resistance，while‘Xuejiuwang’，‘Zhuganqingjiucai’，‘91-2’and‘Kuanjiuwang’had the highest susceptibility to Bradysia odoriphage with poor insect resistance，and resistance of the rest varieties were between the two above.Correlation analysis on the three resistances indicated that there were significant correlations within different indexes.
