The leaf rust resistance gene Lr25, transferred from Secale cereale L. into wheat and located on chromosome 4B, imparts resistance to all pathotypes of leaf rust in South-East Asia. In an F2-derived F3 population, created by crossing TcLr25 that carries the gene Lr25 for leaf rust resistance with leaf rust-susceptible parent Agra Local, three microsatellite markers located on the long arm of chromosome...

AbstractThe recessive adult plant leaf rust resistance (APR) gene Lr48 in CSP44 was tagged using simple sequence repeat (SSR) markers. The population was phenotyped under controlled conditions using pathotype 77‐5 (121R63‐1) at both seedling and adult plant stages. Four microsatellite markers Xwmc175, Xwmc332, Xwmc627 and Xwmc149 were linked to Lr48 and mapped to chromosome...
The recessive adult plant resistance (APR) gene Lr48 in wheat was tagged with flanking random amplified polymorphic DNA (RAPD) markers. Markers S336775 in coupling and S3450 in repulsion with Lr48 were identified in wheat line CSP44. Tests of these markers on available Thatcher near-isogenic lines (NILs) detected the likely presence of Lr48 in TcLr25. A test of allelism of APR involving the cross...
