Abstract

Molecular markers make the pyramiding of rust genes possible in adapted elite lines. In this study we report the microsatellite tagging of leaf rust genes Lr13 and Lr28 in the Leichardt/WAWHT2071 and Sunland/Arrino populations, respectively. Leichardt and Sunland were the sources of resistance genes for Lr13 and Lr28, respectively. F2 and F2:3 populations were used for microsatellite tagging of the genes. Closely linked SSR markers were identified for Lr13 and Lr28 on chromosomes 2BS, 4AL, respectively. Molecular markers for a range of other rust resistance genes (Lr9, Lr19/Sr25, Lr24/Sr24, Lr34/Yr18 Lr46/Yr29, Lr47, Sr26, Sr32, Sr33 and Sr36) are currently being implemented for variety development and germplasm enhancement.
