CucCAP researchers identify QTL for Phytophthora resistance in squash

Phytophthora capsici causes significant yield losses in commercial summer squash production in the U.S.  Deployment of resistant cultivars can complement integrated management practices for Phytophthora, but resistant cultivars are currently unavailable for growers. To facilitate development of resistant cultivars, 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.
