Dry conditions and disease pressure in South Georgia
Specialty crop growers prefer the current dry weather conditions when producing their crops. They want to apply the water needed which helps avert the buildup of disease pressure.
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.
CucCAP researchers develop watermelon breeding lines with broad resistance to Phytophthora capsici
CucCAP researchers developed 5 Phytophthora fruit rot resistant watermelon germplasm lines with high levels of resistance against a broad range of diverse P. capsici isolates collected from across the United States.
