The banded sunflower moth is one of the most pervasive insect pests of sunflower (Helianthus annuus L.) in North America, in large part due to its ability to overwinter in cold climates. The goal of this research is to provide germplasm containing resistance to infestation by the banded sunflower moth while retaining valuable traits, such as imidazolinone herbicide tolerance and high oleic acid content in the seed oil, along with suitable agronomic performance for the northern Great Plains climate and other similar climates where the banded sunflower moth is prevalent. HA 489 (Reg.no. GP-370, PI 691858) is a maintainer inbred germplasm developed by pedigree selection and testcross evaluation that can fill this need. HA 489 has high oleic acid composition, exhibits tolerance to imidazolinones, and provides resistance to banded sunflower moth infestation. This line was released by the USDA-ARS, Fargo, ND, to fill the need for sources of host-plant resistance to important insect pests.
