Abstract: The resistance to stripe rust of 170 winter wheat varieties(lines) from 1949 to 2016 in Sichuan province was identified for two consecutive years. Using DB51/T 713-2007 "Technical regulations for resistance to stripe rust in fields" identification method. 43 varieties(lines) with disease resistance were identified, accounting for 25.29% of the total number of varieties(lines) identified. In the two years identification, 49 materials showed a disease resistance in one year and a susceptible disease in the other year, accounting for 28.82% of the total number of varieties(lines) identified. The remaining 78 varieties (lines) were identified as susceptible for two consecutive years, accounting for 45.88% of the total number of identified varieties(lines). In addition, it was found that local varieties such as Chengdu Guangtou and Kaixian Luohanmai still maintain resistance to the current physiological races of stripe rust bacteria.

Key words: stripe rust of wheat, disease resistance identification, landraces, disease resistance gene
