CucCAP scientists study basis for resistance to squash vein yellowing virus resistance in watermelon

Watermelon production in the southeastern U.S. is subject to severe crop losses due to several viruses, including squash vein yellowing virus (SqVYV). Gene expression analysis of a resistant breeding line by the Kousik group at the U.S. Vegetable Laboratory Charleston SC, indicated potential involvement of a variety of defensive responses. These findings can assist further functional studies and the development of SqVYV-resistant watermelon cultivars.

CucCAP scientists uncover genetic factors influencing flowering time and fruit yield in watermelon

Scientists at the USDA, ARS, U.S. Vegetable Laboratory in Charleston, SC evaluated the USDA, ARS citron watermelon germplasm collection for flowering time and fruit yield traits under field conditions over two years. They used a “genome-wide association study (GWAS)” to detect genomic regions and molecular (DNA) markers associated with flowering time and fruit yield traits. The new molecular markers will be useful in improving watermelon varieties for early flowering and maturity and yield performance via marker-assisted breeding.
