| Abstract: | This paper analyzes the growth and decline,pathogenicity,and feeding species layout of wheat stripe rust CY 33.The result showed that CY 33 was considered of high frequency and toxicity,wide pathogenic range and various feeding varieties.It has become predominant popular race harmful to wheat production in Gansu Province even the whole nation.The toxic group structure of wheat stripe rust has entered into a new period of preponderant Hybrid 46 and Shuiyuan 11 pathogenic groups represented by CY 33 and CY 32... |
