The Future is Green: How Scallion Breeding is Shaping Sustainable Food Systems
For generations, the humble scallion (Allium fistulosum) has been a kitchen staple. But beyond its culinary uses, a quiet revolution is brewing in the world of scallion breeding, driven by factors like climate change, pest resistance, and a growing demand for locally adapted varieties. A recent offering from Driftless Seed Supply, a breeding mix of ‘Evergreen Hardy’, ‘Tokyo Long’, and ‘Parade’ scallions, exemplifies this trend – a move towards diversification and resilience in our food supply.
The Rise of Open-Pollinated and Breeding Populations
Traditionally, vegetable breeding focused on creating stable, uniform hybrids. While effective for yield, this often came at the cost of genetic diversity. Now, there’s a resurgence of interest in open-pollinated varieties and, crucially, breeding populations. These aren’t fixed varieties, but rather dynamic groups of plants allowed to cross-pollinate, creating continuous variation.
The Driftless Seed Supply mix is a prime example. By allowing these three scallion types to interbreed, Dylan Bruce and his team are fostering a population capable of adapting to changing conditions far more effectively than a single, static variety. This approach is gaining traction as climate change introduces unpredictable weather patterns and new pest pressures. A 2023 report by the USDA’s Agricultural Research Service highlighted the importance of genetic diversity in maintaining crop resilience in the face of climate variability.

Pro Tip: When saving seeds from open-pollinated scallions, allow multiple plants to flower and cross-pollinate. This maximizes genetic diversity in the next generation.
Breeding for Specific Challenges: Thrips Resistance and Cold Hardiness
The article specifically mentions breeding for cold hardiness and resistance to onion thrips. These are significant concerns for scallion growers. Onion thrips (Thrips tabaci) are a widespread pest, causing significant damage to alliums. Conventional control often relies on pesticides, but breeding for resistance offers a more sustainable solution.
Researchers at Cornell University are actively investigating genetic markers associated with thrips resistance in onions and related species. [Cornell Thrips Research] This knowledge can be applied to scallion breeding programs, accelerating the development of resistant varieties. Similarly, the demand for scallions that can withstand harsh winters is driving breeding efforts in colder climates, like Wisconsin, where Driftless Seed Supply is based.
The Local Food Movement and Seed Saving
The growing popularity of local food systems is fueling demand for regionally adapted seeds. Gardeners and small-scale farmers are increasingly interested in varieties that thrive in their specific microclimates. This trend is closely linked to seed saving – the practice of collecting and storing seeds from successful plants to use in subsequent seasons.
Seed saving not only reduces reliance on commercial seed companies but also allows gardeners to further adapt varieties to their local conditions over time. The Driftless Seed Supply scallion mix is particularly well-suited for this purpose, providing a diverse genetic base for gardeners to select and breed from. Organizations like Seed Savers Exchange are playing a vital role in preserving and promoting heirloom and open-pollinated varieties. [Seed Savers Exchange]
Did you know? Scallions are perennials, meaning they can regrow year after year from the same root system. This makes them an excellent choice for a low-maintenance garden.
Germination Rates and Seed Quality: A Growing Focus
The reported 98% germination rate for the Driftless Seed Supply scallion seeds (tested November 2025) highlights a growing emphasis on seed quality. Consumers are demanding seeds that are reliable and perform well. This is driving improvements in seed storage, testing, and handling practices.
Advanced seed testing technologies, such as tetrazolium tests and accelerated aging tests, are being used to assess seed viability and predict germination rates with greater accuracy. Companies are also investing in improved seed storage facilities to maintain seed quality over longer periods.
FAQ: Scallion Breeding and Growing
- Q: What is the difference between a hybrid and an open-pollinated scallion?
A: Hybrids are created by crossing two different parent lines, resulting in uniform plants. Open-pollinated varieties allow natural cross-pollination, leading to greater genetic diversity. - Q: Can I save seeds from hybrid scallions?
A: While you can save seeds, they won’t breed true to type. The next generation will likely exhibit a wide range of characteristics. - Q: How early can I start scallion seeds indoors?
A: Up to two months before the last frost. - Q: Are scallions easy to grow?
A: Yes, they are relatively easy to grow and can tolerate a wide range of conditions.
