The efficiency of leaf rust resistance genes in adult plants was studied on near-isogenic lines of Thatcher carrying known leaf rust resistance genes in the artificially inoculated leaf rust nursery of the Agricultural Research Institute of the Hungarian Academy of Sciences in Martonvásár over a five-year period (1997–2001). Eight of the wheat lines tested (Lr9, Lr19, Lr23, Lr24, Lr25, Lr29, Lr35, Lr37) exhibited little or no infection. Lines carrying genes Lr13, Lr44 and LrB were resistant in two years and those carrying Lr34, Lr38 and LrW in three years, after which they suffered moderate or heavy infection. Three lines (Lr12, Lr17, Lr32) proved to be moderately resistant. The majority of the wheat lines tested became heavily infected.
