Abstract
This article reviews past successes and future potential of the use of interspecific hybrids in the breeding of cultivated Helianthus annuus, with emphasis on the necessity for conservation of non-cultivated germplasm. The topics discussed include resistance to diseases and other pests; the development of male-sterile lines for hybrid seed production; introduction of genes for various agronomic traits, such as drought resistance and cold tolerance; and attempts to change the chemical composition of the harvested crop.
