Efficient Methods to Develop New Organic Cultivars: Case Studies of Breeding Julie Dawson, University of Wisconsin-Madison; Michael Mazourek, Cornell University; Jared Zystro, Organic Seed Alliance and University of Wisconsin-Madison The Mazourek group developed this tool for powdery mildew resistance in squash (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0167715). Now, for about $5 per plant a squash breeder can send leaves picked […]

Breeding Cucurbita moschata varieties for resistance to downy mildew
During the 2016 growing season Common Wealth Seed Growers conducted winter squash research that included a variety trial of 23 seedstocks; three selection projects (‘Seminole Pumpkin,’ ‘Chinese Tropical Pumpkin’ and ‘Cuban Neck Pumpkin’); and a breeding trial with F5 seeds from a cross of ‘Seminole Pumpkin’ and ‘Waltham Butternut.’
Pickle Variety Twilight Meeting – Cornell Vegetable Program
Vegetable growers toured an on-farm plot of early generation Cornell downy mildew resistant pickle breeding lines. Dr. Michael Mazourek, Professor of Plant Breeding, and lab members, were on-site to walk growers through the plot and review plant selections. Feedback from growers helps Cornell researchers make selections for the next generation of pickle variety releases. Organic control […]

Breeding Squash for Disease Resistance
Cucurbita spp. Powdery Mildew Phytophthora Blight Virus Diseases Powdery Mildew Powdery mildew is a disease that affects all cucurbits and is important in squash. Resistance was introduced from the wild species, Cucurbita marintezii in C. moschata and C. pepo. The resistance gene, Pm-0, is a single incompletely dominant gene that is commonly deployed in the […]
