HA-343 is specialized breeding material, not a variety for commercial sowing. The line was obtained as a result of crossing HA 89 and the Pervenets variety, which determined its genetic profile.
This line belongs to the maintainer line type (B-line) and is used as a parental form for creating sunflower hybrids. It serves as a source of the high oleic acid content trait in oil.
In breeding work, the line was used as a source of valuable traits, including resistance to diseases such as Verticillium wilt. The morphological characteristics of the line are close to HA 89.
