Abstract: Adult resistance evalution and the correlation between the factors were studied by natural inoculation, and cluster was also investigated based on 241 wheat cultivars which comes from the wheat growing regions of China in this paper.The correlation among the three resistance components indicates that there is positively relationship between infected type was and finally disease index and prevail rate.the results show there was 39 high resistance cultivars by resistance identifying and clustering (16.18%), 111 middle resistance cultivars (46.05%), 68 middle susceptibility cultivars (28.21%), 23 high susceptibility cultivars (9.54%), respectively.
