To determine the inheritance of resistance in Chuanmai 42, it was crossed and backcrossed with the susceptible Sichuan varieties of common wheat Mianyang 26 (MY26) and Mianyang 335 (MY335) for preparing the F2 and BC1 populations. A total of 208 and 337 F2 plants of Chuanmai 42×MY26,Chuanmai 42×MY335, and 171 and 216 BC1 plants of Chuanmai 42/MY26//MY26,Chuanmai 42/MY335//MY335, respectively, were used for resistance analyses.
