USDA Cucurbit Grant 12/07/23 Jordan Powers
Seven East Coast states harvested nearly 102,000 acres of watermelon and cucumber in 2019 and 2020, representing more than 62% ($410 million) and 45% ($180 million) of the U.S. production of the two crops, respectively. Growers of cucurbits — which include melons, pumpkin, squash and cucumbers — face numerous challenges in production, leading to decreased profitability and less produce on grocery shelves.
‘Orange Bulldog’ is an improved pumpkin variety developed by UGA scientists from germplasm collected in the jungles of South America.

University of Georgia graduate student Zach Matteen conducted trials on 11 varieties of winter squash at UGA's Durham Horticulture Farm in Watkinsville, Georgia, on land used to grow organic crops. Matteen tested winter squash varieties 'Waltham' butternut, 'Zeppelin' delicata, 'Metro PMR' butternut, Seminole pumpkin, Choctaw sweet potato, 'Thai Kang Kob' tropical pumpkin, 'Thelma Sanders' sweet potato and a fifth-generation cross of 'Waltham' butternut and Seminole pumpkin. He found that the two sweet potato squashes and Seminole, tropical and tan cheese pumpkins held up best against squash pests and diseases. CAES News
