Abstract
Sunflower (Helianthus annuus L.) is a crop native to North America for which there are no genetically modified commercial varieties. Some of
the transgenic traits incorporated in other crops have already been subjected to research and experimentation in sunflower. Several new traits have
also been noted, with the most relevant of these being the aim to increase latex production. GM sunflower release would modify crop management
through improved mineral nutrition, weed control, insect and disease resistance, and product quality. In this research, the traits investigated were
reviewed and analyzed in connection with main crop constraints. These characters could potentially influence agro-ecosystem components and
produce a significant environmental impact. In regions where sunflower coexists with wild relatives this situation could affect germplasm
resources, with this being especially important at the centre of origin and where Helianthus populations established in Africa, Asia, and Europe.
