Summary: This study mapped QTLs associated with resistance to leaf spot, leaf rust, stripe rust, and common bunt in two wheat populations using the IWGSC physical map. A total of 82 QTLs were identified, with 29 of them associated with disease severity in all environments. This methodology provides a resource for comparing QTLs across different populations and studies based on improved physical information.

Summary: The adult-plant stripe rust resistance gene, Yr86, in Chinese wheat cultivar Zhongmai 895 was mapped to the physical interval 710.2-713.2 Mb on chromosome 2A. This gene provides stable resistance to stripe rust at the adult-plant stage and has the potential to be a new gene for this type of resistance. Multiple KASP markers associated with Yr86 were developed and can be used for marker-assisted selection and further studies on this resistance gene.

Summary: A multi-year evaluation of the Vavilov wheat diversity panel identified new sources of adult plant resistance to stripe rust. Genome-wide association studies revealed key genomic regions influencing resistance, including seven novel loci. These findings are important for broadening the genetic bases of YR resistance in modern wheat varieties.

Summary: This study identified quantitative trait loci (QTL) for stripe rust resistance in wheat using a back-cross inbred-line population. A major QTL conferring all-stage resistance was identified on chromosome 1B, along with seven additional QTLs associated with adult plant resistance. This research provides valuable insights for improving resistance to stripe rust in wheat.

Summary: Stripe rust, a major disease affecting wheat yield globally, has become a significant issue in Egypt. Research conducted on 95 wheat genotypes from 19 countries revealed high genetic variation and identified 13 stable markers associated with resistance to the Egyptian race(s) of stripe rust. Two German genotypes were found to carry the targeted allele of all significant DArT markers linked to stripe rust resistance, offering potential for improving resistance under Egyptian conditions.

Summary: The study combined quantitative and population genetic methods to identify loci under selection for stripe rust resistance in an Austrian winter wheat breeding population from 2008 to 2018. A total of 150 resistance loci were identified, with 62 showing significant evidence of selection over time. This genetic information can be utilized for marker-assisted selection and genomic prediction applications.

Summary: This study determined the genetic basis of resistance to leaf rust (LR) and stripe rust (YR) in wheat variety Borlaug 100. Multiple resistance genes were found to significantly affect the severity of the diseases, and their additive and interactive effects were observed. The results provide resistance sources for wheat breeding programs.

Summary: This study investigated the genetic basis of stripe rust resistance in wheat and identified four resistance quantitative trait loci (QTLs). Among them, QYr.lrdc-2A.1 and QYr.lrdc-2B were the most stable QTLs, and the severity of stripe rust was significantly reduced when both were present along with QYr.lrdc-5A. In addition, the study found that QTLs detected in different locations may vary.

Summary: This study identified several genes and loci conferring resistance to leaf rust and stripe rust through genetic and QTL mapping research, including a novel pleiotropic gene conferring resistance to both leaf rust and stripe rust in an Afghan landrace. The discovery of these genes and loci is significant for breeding efforts to develop durable resistance to multiple rust diseases.

Summary: The timely and accurate identification of stripe rust and leaf rust is essential in effective disease control and the safe production of wheat worldwide. This study investigated methods for identifying the two diseases on different wheat varieties based on image processing technology. By building multi-variety disease identification models using optimal feature combinations from disease images, satisfactory identification performances were achieved.

Summary: We identified 20 reliable quantitative trait loci (QTLs) for seedling and adult plant resistance to stem rust in a association mapping panel of 400 germplasm accessions. Gene ontology analysis identified 21 potential candidate genes underlying these QTLs, including a leucine rich repeat receptor (LRR) and P-loop nucleoside triphosphate hydrolase. Four of the QTLs were validated using the KASP method, and these QTLs have the potential to be used in wheat improvement programs for developing disease resistant varieties.

Summary: This study investigated the application of genomic selection in major diseases of spring wheat and compared the impact of different models on prediction accuracies. The results showed that the M3 model, which incorporated GE interactions, outperformed the M2 model in reducing residual variance and improving prediction accuracies.

Summary: In this study, a wheat-rye multiple disomic substitution line, SLU126 4R (4D), 5R (5D), and 6R (7D), was used and crossed with Chinese Spring ph1b to induce homeologous recombination, resulting in introgressions with reduced rye chromosome segments that possessed resistance against wheat stripe rust. Through genotyping-by-sequencing (GBS) platforms and aligning putative SNPs to annotated rye NLR genes, the physical positions of NLR genes related to stripe rust resistance were identified. The study also confirmed the existence of a rye translocation containing the stripe resistance gene, which provides an additional asset for wheat improvement.

Summary: Barley lines were evaluated for trait performance under deficit and full irrigation. A genome-wide association scan identified significant SNPs associated with the studied traits under both water regimes. Some markers showed pleiotropic effects on multiple traits. These findings provide insights for predicting optimal barley accessions under different water conditions.
