Relocation of 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 was mapped to chromosome 2A based on its repulsion linkage with in an Arina/Forno recombinant inbred line (RIL) population. Attempts to identify markers closely linked to using available genomic resources were futile. This study used an Arina/Cezanne F RIL population to identify markers closely linked with .

Fine Mapping of Using 90K SNP Chip Array and Flow-Sorted Chromosome Sequencing in Wheat.

Leaf rust, caused by , threatens global wheat production due to the constant evolution of virulent pathotypes that defeat commercially deployed all stage-resistance (ASR) genes in modern cultivars. Hence, the deployment of combinations of adult plant resistance (APR) and ASR genes in new wheat cultivars is desirable. Adult plant resistance gene was previously mapped on the long arm of chromosome 4B of cultivar VL404 and flanked by microsatellite markers (8.

Characterisation and mapping of adult plant stripe rust resistance in wheat accession Aus27284.

A new adult plant stripe rust resistance gene, Yr80, was identified in a common wheat landrace Aus27284. Linked markers were developed and validated for their utility in marker-assisted selection. Stripe rust, caused by Puccinia striiformis f.
