The international HelEx project has developed a sunflower variety that produces six times more nectar and pollen than conventional crops. Researchers achieved this by crossing drought-tolerant wild sunflowers from the United States with established European breeding lines.
Why it matters
Climate change and water scarcity threaten sunflower yields across Europe, which accounts for 75% of global production. These new hybrids aim to secure food supplies while meeting rising demand for plant-based proteins.
The new variety produces six times more nectar and pollen than traditional cultivars, balancing these gains against standard seed oil content of 43% and 17% protein. Researchers identified specific genetic markers controlling UV color and nectar sugar levels to drive these traits.
The players
HelEx project
A research consortium comprising 17 partner organizations focused on integrating wild genetics into commercial sunflower breeding.
The details
Scientists employed both conventional breeding and gene editing to integrate traits from arid-region wild sunflowers into European varieties. This approach targets specific genes influencing pollinator attraction, which helps sustain the ecosystem services necessary for crop fertilization. The process involved screening wild populations for drought resilience and crossing those high-performing specimens into commercial production strains.
Timeline
2028: New sunflower variety is expected to become commercially available.
The Tech Race
The HelEx project is currently validating its hybrid lines against the intensifying pressures of European drought conditions. This effort follows a broader trend of utilizing wild plant genomes to bypass the limited genetic diversity found in modern monoculture crops.
Farmers across Europe will see these new hybrids reach the market in 2028 to combat declining yields in regions like Bulgaria and Greece. The adoption of these varieties aims to stabilize the supply of sunflower-derived oils and proteins for the broader food industry.
The takeaway
The successful cross-breeding of wild sunflower traits demonstrates a scalable path toward stabilizing climate-vulnerable agricultural sectors. Watch for the 2028 commercial rollout to determine the impact on actual regional harvest totals.
What happens next
Industrial partners plan to deploy these hybrid sunflower varieties across Europe following the expected 2028 commercial release.
