- * Thousands of wheat landrace accessions in the National Small Grains Collection (NSGC) were tested for resistance against common stem rust races in field trials conducted in Minnesota and Kenya.
- * 45 landrace accessions showed consistent resistance in trials in both locations and lacked known resistance gene alleles, indicating they may offer new avenues for developing stronger wheat varieties against stem rust.
Article Synopsis
- * Pg13 is crucial for stem rust resistance in North American oat cultivars and will aid in routine selection practices like gene pyramiding and backcrosses.
- * High-density linkage maps and genome-wide associations confirmed Pg13's location at approximately 67.7 cM on linkage group Mrg18, coinciding with specific translocation breakpoints and other resistance genes, with reliable KASP assays created for breeding use.
Two major dwarf bunt resistance QTLs were mapped to a known Bt9 locus and a novel locus. The associated KASP markers were developed and validated in other two populations. Dwarf bunt (DB), caused by Tilletia controversa J.

- Crown rust disease, caused by the fungus Puccinia coronata f. sp. avenae, significantly affects oat production in various regions, and while many resistance genes exist, only a few have known locations on chromosomes.
- The study aimed to identify the location of the Pc53 gene using linkage mapping and to find linked SNPs for improving oat breeding through marker-assisted selection.
- The Pc53 gene was mapped on linkage group Mrg08 at 82.4 cM, and the closest SNP marker identified can help in breeding programs focused on enhancing resistance to crown rust disease.*
