Abstract: Mianmai 39, a new wheat variety released in Sichuan province in 2005, was highly resistant to Chinese newly predominant races of Chinese Yellow Race (CYR32) at adult stage. In order to determine the inheritance of resistance in Mianmai 39,seven resistant varieties and four susceptible varieties were used to cross with Mianmai 39, thus the F1 and F2 population were obtained. Resistance of parental varieties and their hybrid progenies were analyzed genetically by artificial inoculation with CYR32 at adult stages. The results showed, the resistance to stripe rust race CYR32 in Mianmai 39 at adult stages were controlled by one dominant gene,which derived from the variety Guinong 21.The gene might be an allelic locus of YrCH42 and Yr26,but differ to those in Guinong19-4 and liaochun 10, and also differ to those in oxley and 96EW39（SW2148）which derived from CIMMYT. The resistance of the seven resistant varieties were also discussed.
