%X Stripe rust (or yellow rust) of wheat (Triticum aestivum), caused by Puccinia striiformis f. sp. tritici, is one of the most important diseases of wheat in China. Since Sichuan is one of the most important over-summering areas of P. striiformis f. sp. tritici in China, the objective of this study was to determine genetic structure of P. striiformis f. sp. tritici populations in this region. Population genetic diversity was investigated for the P. striiformis f. sp. tritici population from different areas in Sichuan province with TP-M13-SSR technique. The important conclusion is that P. striiformis f. sp. tritici populations were considerably diversity in Sichuan, while there were different between regions. Genetic diversity for the pathogen population from northwest of Sichuan and Sichuan Basin were much higher than that from other regions. Genetic differentiation was also investigated. The results showed that interregional genetic variation accounted for 14.92% of the total, while interpopulational variation 23.06% and intrapopulational variation 60.02%. Moreover, our molecular data on gene flow and genotype confirmed the migration of pathogen populations among regions in Sichuan, in particular, between northwest of Sichuan and Sichuan Basin.
