Determine the median stalk moisture level that triggers the girdling behavior of D. texanus larvae. Plot post-maturity changes in stalk breakage forces in two stay-green hybrids versus a conventional NuSun hybrid and correlate these with moisture content and larval girdling.

  Title Development of a Perennial Sunflower for Use in an Integrated Blackbird Management System
  Investigator Michael Kantar, University of MN
  Description 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 and divert them from commercial fields.
