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.

油葵种子保持剂种质HA 489对带状向日葵蛾的抗性登记

带状向日葵蛾是向日葵（向日葵）中最普遍的害虫之一。L.），主要是由于其在寒冷气候下能够越冬的能力。这项研究的目的是提供能够抵抗带状向日葵蛾侵染的种质，同时保留有价值的特性，例如咪唑啉酮除草剂耐受性和种子油中的高油酸含量，以及适合大平原北部气候和干旱的农艺性能。在带状向日葵蛾盛行的其他类似气候中。HA 489（Reg。no。GP-370，PI 691858）是通过谱系选择和测交评估开发的自交种质，可以满足这一需求。HA 489具有较高的油酸成分，对咪唑啉酮具有耐受性，并能抵抗带状向日葵蛾的侵染。这条线是由美国农业部ARS，北达科他州的法戈发布的，
