The higher yielding cultivars as well as advanced cultivation techniques combining with these varieties are the most proper solution to reduce hunger and to feed the world. New variety development with new yield and stress tolerant traits could be possible mostly from utilizing the new genetic resources. The complex of cultivated sunflower Helianthus annuus L. and its relatives of the same genus is an appropriate model for using the genetic diversity of wild Helianthus species for developing new sunflower genotypes. Until today, many new sunflower varieties have been created based on the use of wild germplasm. © 2021 Elsevier Inc.
