Vegetables comprise an economically important segment of Georgia’s agricultural production, so there is a need for vegetable breeders to have comprehensive, crop-specific data on grower priorities, varietal performance, and production constraints.
UGA’s vegetable breeding program performed a needs assessment survey to assess growers’ preferences, the results of which are presented in this resource. This data will be used to inform the development of regionally adapted high-performing vegetable varieties.
