Economic importance:

• Gene sources: disease resistance for sunflower   (based on resistance to downy mildew, fide Helia 32:67. 2009)
  
• Gene sources: pest resistance for sunflower   (based on the development of lines for resistance to Orobanche, fide Helia 32:69. 2009)
  
• Gene sources: tertiary genetic relative of sunflower   (based on hybrid formation with H. annuus, fide Helia 32:69. 2009)
  
• Materials: potential as lipids   (due to high oil content, fide Econ Bot 45:6. 1991)
  
• Weed: potential seed contaminant   (fide F Ariz)
