Abstract: The aim was to provide a theoretical basis for future sunflower breeding objectives.By planting oil and edible sunflower under different density conditions,the current breeding direction of sunflower was discussed according to the field agronomic traits,yield traits and characteristics of different varieties.Through density testing,it was concluded that sunflower variety breeding not only requires high quality,high yield and good resistance,but it also selects varieties with high quality,high yield,compact plants,small leaves,good ventilation and light transmittance in the field,lodging resistance,dense planting resistance and suitability for mechanized operation.Oil sunflower requires high oil content and high oleic acid content in seeds.Edible sunflower requires good commercial properties of the seeds but the edible sunflower seeds are not easy to peel after mechanical harvesting,and the commercial properties remain unchanged.The discussion on the future breeding objectives of sunflower is helpful for the renewal of sunflower varieties,so as to promote sunflower production and better serve the development of the sunflower industry.
