  "abstract": "Genomic selection (GS) is a promising approach for improving wheat resistance to rust diseases. This study focused on two major rust diseases: leaf rust caused by Puccinia triticina and stem rust caused by P. graminis f.sp. tritici. The training population consisted of 186 wheat accessions with a wide range of resistance levels, while the breeding population consisted of 103 wheat breeding lines. Both populations were genotyped using the Diversity Arrays Technology (DArTseq) platform. The training population was phenotyped under field conditions at two locations over at least three years. In addition to visual assessment of disease symptoms, pathogen content in host plants was quantified using real-time PCR. Six genomic prediction models were tested in a single-trait framework, and the Bayes A model showed the best performance according to the selected decision criteria. Prediction accuracies ranged from 0.79 to 0.75 for stem rust and from 0.42 to 0.38 for leaf rust. Bayesian Ridge Regression (BRR) was selected for multi-trait GS. A very high correlation (0.98–1.00) was observed between genomic estimated breeding values obtained from the single- and multi-trait analyses. Twenty-one promising breeding lines were identified using a Kullback–Leibler loss function combined with average genetic similarity. The selected lines showed a potential improvement in resistance of 16% for stem rust and 5% for leaf rust. GS, especially in multi-trait arrangement, proved to be a good tool for accelerating breeding efficiency for combined and complex traits.",
