This project aimed to identify improved cauliflower cultivars for the fresh, processing and export markets. A series of 10 cultivar by planting time trials were conducted on grower properties throughout the Adelaide Plains and Adelaide Hills during 1998 and 1989. These trials evaluated more than 60 cultivars and were accompanied by a series of 4 field days for growers, seedling growers and seed companies. Standard commercial production practices were used, with trial sites being located within commercial cauliflower crops.
