Four molecular markers linked to Lr44 resistance to wheat leaf rust at seedling stage were identified using AFLP, near-isogenic lines (NIL) and F_2 progeny from a cross of Thatcher, a susceptible line, with Lr44 NIL in Thatcher background. The genetic map showed that the distances between Lr44 and markers: Paag:Mcta_(300), Paac:Mcgt_(85), Paag:Mcta_(395), Paag:Mcgt_(90) was 0.01 cM, 1.1 cM, 3 cM, 2.2 cM, and 2.8 cM, respectively. The identification of AFLP markers linked to Lr44 facilitates establishment of...
