CucCAP scientists use genomic approaches to facilitate breeding for PRSV-W resistance in squash

Papaya ringspot virus-W (PRSV-W) causes severe yield losses in squash production.  The Meru laboratory at the University of Florida identified a single QTL for resistance on Chromosome 09 of the C. moschata genome.  Subsequent testing identified two SNP markers as potential targets for marker-assisted selection. The findings of this study will facilitate breeding for resistance against PRSV-W in commercial squash cultivars.
