Relocation of Sr48 to Chromosome 2D Using an Alternative Mapping Population and Development of a Closely Linked Marker Using Diverse Molecular Technologies
The Ug99-effective stem rust resistance gene Sr48 was mapped to chromosome 2A based on its repulsion linkage with Yr1 in an Arina/Forno recombinant inbred line (RIL) population.Attempts to identify markers closely linked to Sr48 using available genomic resources were futile.This study used an Arina/Cezanne F5:7 RIL population to identify markers cl
