Start Date: Sep 15, 2012
End Date: Sep 14, 2017
Sunflower germplasm in various stages of development will be grown in field or greenhouse conditions to provide samples of naturally-produced plant volatiles. Chemical analysis, including gas chromatography, will be used to identify and quantify components in volatile blends. Insect responses to volatiles will be evaluated indirectly with choice tests or directly with physiological tests (e.g., via electroantennogram). Additional field tests of resistance may be used to further validate patterns detected in germplasm not previously used for sunflower insect resistance.
