The Development of Perennial Sunflower for Wildlife and Food Uses.

The objective of this research is to use current genetics and plant breeding techniques to introgress genes for perennial habit from Helianthus tuberosus L. (2n=6x=102) into domesticated sunflower (Helianthus annuus L., 2n=2x=34). H. tuberosus is part of the secondary gene pool of sunflower and has been used as a donor of many disease resistance traits, most notably Sclerotina resistance, making it an excellent donor for perennial habit. Because of previous success in gene transfer from H. tuberosus, we believe we will be successful in transferring perennial habit into annual sunflower, thus creating a perennial sunflower with high enough yield to attract blackbirds diverting them from commercial fields and eventually with enough yield for oil production.
