論文摘要：  Puccinia striiformis  Westend. f. sp.  tritici  Erikss. ( Pst ) infects wheat and causes stripe rust. The rust is heteroecious with wheat as the primary uredinial and telial host and barberry ( Berberis  spp.) as the alternate pycnial and aecial host. More than 40  Berberis  species have been identified to be alternate hosts for  Pst , and most of these are Chinese  Berberis  species. However, little is known about  Berberis  species or their geographic distributions in the Yunnan-Guizhou plateau in southwestern China. The Yunnan-Guizhou plateau is considered to be an important and relatively independent region for evolution of the wheat stripe rust pathogen in China because the entire disease cycle can be completed within the region. In this study, we conducted a survey of barberry plants in the Yunnan-Guizhou plateau and identified the eight  Pst  susceptible  Berberis  species under controlled conditions, including  B. julianae ,  B. tsienii ,  B. veitchii ,  B. wilsonae ,  B. wilsonae  var.  guhtzunica ,  B. franchetiana ,  B. lepidifolia  and  B. pruinosa . These species were reported for the first time to serve as alternate hosts under controlled conditions for the wheat stripe rust pathogen.
