Rose ( spp.) is one of the most economically important ornamental species worldwide. Flower diameter, flower weight, and the number of petals and petaloids are key flower-size parameters and attractive targets for DNA-informed breeding.

Rose rosette disease (RRD), caused by the rose rosette emaravirus (RRV), is a major viral disease in roses ( sp.) that threatens the rose industry. Recent studies have revealed quantitative trait loci (QTL) for reduced susceptibility to RRD in the linkage groups (LGs) 1, 5, 6, and 7 in tetraploid populations and the LGs 1, 3, 5, and 6 in diploid populations.

Black spot disease (BSD) () is the most common and damaging fungal disease in garden roses (.). Although qualitative resistance to BSD has been extensively investigated, the research on quantitative resistance lags behind.

Rose rosette disease (RRD), caused by the (RRV), is a major threat to the garden rose industry in the United States. There has been limited work on the genetics of host plant resistance to RRV. Two interconnected tetraploid garden rose F biparental mapping populations were created to develop high-quality tetraploid rose linkage maps that allowed the discovery of RRD resistance quantitative trait loci (QTLs) on linkage groups (LGs) 5, 6, and 7.

Resistance to rose rosette disease (RRD), a fatal disease of roses ( spp.), is a high priority for rose breeding. As RRD resistance is time-consuming to phenotype, the identification of genetic markers for resistance could expedite breeding efforts.
