Leaf rust resistance gene
Lr47 is located within a interstitial segment of
Triticum speltoides
Taush. 7S chromosome translocated to the short arm of chromosome 7A of bread wheat. This gene is resistant against currently predominant races of leaf rust from Argentina. The objectives of this study were to identify microsatellites linked to this source of resistance as a potential tool to introgress this source of resistance. Isogenic lines with and without
Lr47 developed from 10 cultivars/breeding lines as well as 10 microsatellites previously mapped in 7AS chromosome were used in this study. Microsatellite
gwm 60 was the only marker that co-segregated completely linked to
Lr47. These data indicate that
gwm 60 could be a valuable marker to introgress
Lr47 in wheat germplasm.
