Sunflower seeds are one of the most important sources of vegetable oil in the world. Additionally, they are used for confectionery and snack food, as well as for bird and pet food. Sunflower germplasm used for food differs between Morocco and Spain. Whereas sunflower seeds used for food in Morocco are mainly obtained from oilseed-type cultivars with black achenes and low hull proportion, those used in Spain derive from confectionery-type cultivars with black and white striped achenes and high hull proportion. The objective of this research was to evaluate the performance and seed quality of Moroccan and Spanish sunflower germplasm used for food. Six cultivars from Morocco and six landraces from Spain were evaluated in replicated field trials in Aïn Taoujdate (Morocco) and Córdoba (Spain) in 2009. Seed yield, hundred-achene weight, hundred-kernel weight, achene oil content, kernel oil content, and fatty acid profile were measured. The results showed that confectionery-type and oilseed-type cultivars did not differ in seed yield, hundred-kernel weight and kernel oil content. Since confectionery-type cultivars from Spain performed similarly to local oilseed-type cultivars, they could be introduced to diversify the offer of in-shell sunflower seed snack in Morocco.
