The Roegneria kamoji accession ZY 1007 was resistant to the mixed predominant races of Puccinia striiformis f.sp. tritici ( Pst) in China based on field tests at adult-plant stage. The seedling resistance evaluation of ZY 1007 showed that it was resistant to stripe rust physiological strains CYR29, CYR33 and PST-V26, which were the predominant races of Pst in China. The female parent R. kamoji cv. Gansi No.1 (susceptible to Pst) was crossed with ZY 1007 (resistant to Pst). Parents, F1 and F2 populations were tested in a field inoculated with the mixed urediniospores. ZY 1007 and all the observed 11 F1 hybrid plants were resistant, while plants of Gansi No.1 were susceptible. Among the 221 F2 plants, 168 plants were resistant and 53 were susceptible, and the segregation of resistant and susceptible plants fits 3R:1S ratio ( χ2 = 0.074, P > 0.75). It confirmed that the resistance of stripe rust in ZY 1007 was controlled by a single dominant gene and temporarily designated as YrK1007. [ABSTRACT FROM AUTHOR]
