[Objective] The aim was to screen out wheat cultivars which were resistant to wheat stripe rust at whole growth period. [Method]The resistance of six wheat cultivars at seedling and adult-plant stages to stripe rust was identified through laboratories under artificial inoculation and natural in the field-induced disease. [Result] The resistance of six wheat cultivars to wheat stripe rust had significant difference,and there was difference between seedling stage and adult-plant stage. Chuanmai 107,Yumai 18 and Mianmai 28 were resistant to stripe rust at whole growth period,among them Chuanmai 107 had good comprehensive traits,so it could be applied in large area; Yumai 18 and Mianmai 28 showed nearly immune at seedling stage,and showed high resistance and resistance at adult plant stage,respectively,so it was proposed a moderate planting in production. Yangmai 11,Jinmai 54 and Jimai 20 showed resistance at seedling stage,but susceptible at adult plant stage,so they should not be used in production. All identification factors on correlation analysis showed positive correlation of various factors. [Conclusion]The results provided theoretical basis for selection of wheat in Sichuan Province.
