Gregory Inzinna hopes to identify resistance genes in Cucurbita and provide the seed and vegetable industry with resistant breeding lines and markers they can use in their work.

CucCAP scientists genetically characterize the USDA germplasm collections for squashes and pumpkins
This article presents the analysis of genotype data generated through genotyping-by-sequencing of the USDA germplasm collections of Cucurbita pepo, C. moschata, and C. maxima.
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.
Early Career Scientist Spotlight | Libby Indermaur
Libby is identifying which of Michael Mazourek’s Cucurbita moschata and C. maxima breeding lines are: 1) resistant to powdery mildew and 2) candidate replacements for the susceptible cultivars used in the processing industry.
CucCAP researchers identify QTL for Phytophthora resistance in squash
Scientists at the University of Florida led by Geoffrey Meru characterized resistance to Phytophthora crown rot in PI 181761 and identified a major QTL on chromsome 13. Several SNP markers were designed to target this QTL for marker-assisted selection.
