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.
