Abstract	Elucidation of the genetic basis of the highly effective resistance in Era wheat to Puccinia recondita f sp tritici could assist breeders in reconstructing similar Lr gene combinations in other cultivars. Attempts to relate the presence of Lr10, Lr13, and Lr34 with the expression of adult-plant resistance showed that a combination of these genes did not necessarily confer high levels of resistance to pathotype UVPrt8 of P.r. f. sp. tritici. The most resistant adult F2 plants derived from a cross between Era and line RL6058 was homozygous for Lr10, Lr13, and Lr34 but other F2 plants exhibiting intermediate levels of adult-plant resistance also appeared homozygous for all three genes. In the leaf rust-susceptible background of Line E, no clear relation ship between Lr13 and expression of adult-plant resistance derived from Era was observed. Limited evidence was obtained that Lr10 in association with an unknown gene or Lr10 inter acted with Lr34 to confer an improved level of resistance to leaf rust in certain plants. Mostly results indicated a lack of interaction among Lr10, Lr13, and Lr34. It seems unlikely that wheat breeders will be able to reconstruct a similar Era-type of leaf rust resistance by combining Lr10, Lr13, and Lr34.
