Abstract
Microsatellite was carried out in Thatcher, six near-isogenic lines and F2 progeny of TcLr19xThatcher to develop molecular markers for leaf rust resistance gene Lr19. Thirteen primer pairs were screened, of which one primer pair Xgwm44 displayed polymorphsim in the population of TcLr19, Thatcher, and their F2 generations. One marker closed linked to Lr19 resistance trait was obtained, and was named Xgwm44139 bp with the genetic distance 0.9 cM. The research shows that Lr19 has more potential in marker-assisted breeding programs in wheat and provides a step stone for mapping genetic map, physical map and the eventual cloning.
