ADAPT
The ADAPT community science program is an interactive way to get involved in Seed Savers Exchange’s mission of preserving and sharing our food crop heritage.
What is ADAPT?
The ADAPT community science program is a fun and exciting way to get involved in Seed Savers Exchange’s mission of preserving and sharing our food crop heritage.
Participants in ADAPT grow varieties selected from the seed bank in their own gardens and send us feedback on the yield performance, stress tolerance, growth cycle, etc. This information helps us better understand the performance of these varieties in different regions and climates, and helps guide SSE’s regeneration efforts, distribution priorities, and future catalog offerings.
How It Works
In early January each year, Seed Savers Exchange releases details on the trials we’re offering for the upcoming season. Participants select the crop(s) they want to trial and are then randomly assigned three varieties. In the first week of March, SSE sends participants a kit containing seeds, plant labels, a datasheet, and instructions for submitting their data. Participants are asked to grow the three varieties side-by-side under the same conditions. SSE does not require a minimum number of plants. Participants evaluate each variety on a handful of key characteristics, including yield, flavor, earliness, appearance, and disease resistance. Data is submitted via a web platform called SeedLinked, which Seed Savers Exchange has partnered with since 2018.
The platform provides both a user-friendly computer interface and a free smartphone app that participants can use to track, share, and learn about regional seed and variety performance. Watch this video about SeedLinked.

Community Scientists Make A Difference
The 2018 community science programs, consisting of 80 Seed Savers Exchange members, helped us take another giant step forward in preserving our collection.

Testimonials
Cathie Pitman
"I really enjoy trialing plants for the ADAPT Program. I look forward to the excitement of seeing how the plants and their fruits turn out, sharing the information of their characteristics both good and bad, and interacting with other ADAPT growers.”
Bjorn Bergman
"Seed Savers Exchange's ADAPT Program is a highlight for me each growing season. I love getting to grow heirloom varieties from SSE's seed bank and provide my feedback on them so that the preservation team can decide what varieties to introduce to future SSE catalogs. The ADAPT program makes me feel like I am actively participating in Seed Savers Exchange's mission of getting more people to grow and be educated about heirloom seeds."
