Seed Saving

Across the globe there is growing awareness once again of the importance of breeding and saving seed for plant varieties specifically adapted to the needs and conditions of particular communities and regions, an important component of healthy food systems. The reasons for this work are broad, encompassing a greater desire for more locally suited varieties and biodiversity supporting health and resilience, to issues of food sovereignty. The following resources provide an introduction to this vast and growing body of work. Cornell community members can refer to the research literature section of this guide for database tools that can be used to find more scholarly resources.

Cornell University Initiatives

  • Cornell Garden Based Learning projects, including:
    • Vegetable varieties investigation (Vvi) a citizen science approach to preserving biodiversity and connecting with community, designed to engage youth.  Participants interview gardeners about their opinions on vegetable varieties, and submit their findings to:
    • Vegetable Varieties for Gardeners, an online database that serves as a nation-wide online library of vegetable variety data.
  • Cornell University Agriculture Experiment Station
  • Plant Breeding & Genetics Department related programs, including:
    •, a curated, open-source, data resource for comparative genome analysis in the grasses, facilitating research and discovery work by researchers. Using controlled vocabularies and web-based displays, things like genetic diversity can be explored and mapped, potentially significantly increasing the efficiency of selections made in plant breeding programs. Extensive list of related resources. Possible model component of a bioregional breeding program, indexing and monitoring genetic diversity.
    • Small Grains Project develops innovative approaches to crop improvement, encompassing molecular genetics, physiology, pathology, and breeding contributing to the development of superior crop varieties.
    • USDA AFRI project – Enhancing Education and Research for Plant Disease Resistance Supporting a transition to sustainable agricultural systems that focus on local production and prepare for the consequences of global warming, helping train plant breeders to utilize genomic tools, navigate a wealth of data with bioinformatics and synthesize research perspectives from both vegetable and grain breeding as part of their modern skill set, bringing together fundamental and applied plant breeding research.
  • USDA-ARS, Plant Genetic Resources Unit, located on the Geneva, NY Campus of Cornell University, is a component of the National Plant Germplasm System (NPGS). It conducts workshops and provides training opportunities in seed production and seed cleaning to small-scale seed companies and regional growers.

  • Navdanya started as a program of the Research Foundation for science, Technology and Ecology (RFSTE), a participatory research initiative founded by Dr. Vandana Shiva. The main aim of the Navdanya biodiversity conservation program is to support local farmers, rescue and conserve crops and plants that are being pushed to extinction and make them available through direct marketing.
  • Seeds of Diversity is a Canadian volunteer organization that conserves the biodiversity and traditional knowledge of food crops and garden plants.
  • Seed Savers Exchange is a non-profit organization dedicated to saving and sharing heirloom seeds. Their mission is to conserve and promote America's culturally diverse but endangered food crop heritage for future generations by collecting, growing, and sharing heirloom seeds and plants. SSE encourages “participatory preservation” amongst its members.

  • Organic Consumers Association list of organic seeds, heirloom seeds, un-treated seeds, open-pollinated seeds, and organic seed suppliers.
  • Organic Growers' Research and Information-Sharing Network (OGRIN) Northeast US based organization that generates practical information for organic farmers and gardeners through farmer participatory research, review articles and fact sheets on issues critical to organic farming, and by providing forums for information-exchange between growers.
  • Organic Seed Alliance advances the ethical development and stewardship of the genetic resources of agricultural seed, through collaborative education, advisory services, and research programs with organic farmers and other seed professionals. Offer a variety of useful publications including policy reports, plant breeding and variety trial guides, seed production guides, online tutorials, worksheets, record sheets, and proceedings from biennial Organic Seed Growers Conference.

Industry/Trade Groups & Resources

  • American Seed Trade Association ASTA is concerned with the development, marketing and movement of seed, associated products and services throughout the world. Activities focus on intellectual property protection, regulatory matters, new technologies and communication and marketing in support of the seed industry. Provides a list of seed testing and accreditation agencies.

Seed Libraries

Adapted from SSE: Seed saving networks across the country are working to preserve regional crops and biodiversity by establishing “seed libraries”. A seed library is a place where plant genetics, in the form of seeds, are stored for research and public use. A grower borrows a certain amount of seeds, grows them out as a crop, harvests some of the seed, and returns the same amount of seeds he or she borrowed the next year. A seed library is a means by which a region can store and continually select from and improve upon the genes of its regionally adapted varieties, teach the public about farming and biology, and store alternative species of plants in case a widely used variety succumbs to a new disease or pest.

  • Center for a New American Dream hosted a webinar about how to start a seed lending program at your public library. Topics include funding models, obtaining starter seeds, patron orientation, and more. The webinar features speakers from seed libraries around the country.
  • Hudson Valley Seed Library grew from a small town library project into an online seed library focused on the Northeast with a full seed catalog for all gardeners. Today, it has its own seed farm where heirloom and open-pollinated seeds are grown, saved, and packed by hand, in unique “Art Packs".
  • Jane Addams' Hull-House Seed Library aims to not only provide seeds, but a historical background of each plant. By documenting the seeds journey from the original farmer to a seed borrower to the plot of dirt, there is an appreciation and comprehension of what heirloom signifies. The Seed Library asserts the connection between social, environmental and economic systems within the Chicago community.
  • Richmond Grows is a non-profit seed lending library located in the Richmond California Public library. The Library is open to everyone and provides, in addition to seeds, education about growing and saving seeds and organic gardening. Their website includes a fairly extensive list of other seed libraries around the world.
  • Seed Libraries Social Network is a national organization supporting existing and emerging seed libraries. Their site provides a range of useful resources, including instructions for sharing your seed inventory, a bibliography on seed stewardship, and support resources for starting your own seed library.

Seed Sovereignty

  • Campaign for Seed Sovereignty Effort led by European Campaign for Seed Sovereignty, seeking to address multiple issues related to seed saving, including protecting open access to seeds free of legal restrictions, and the right for all growers to obtain, re-sow, save and distribute seed.  The "Resilient Seed" booklet and film available on their site examines the monopolisation of seeds by agrochemical firms and EU regulation on seeds.
  • Farmer Seeds Nyéléni Newsletter Number 3. The international Nyéléni newsletter aims to be the voice of the international movement for Food Sovereignty.
  • Seed Freedom –site started by Vandana Shiva, supporting Global Alliance for Seed Freedom, a global campaign to alert citizens and governments around the world on how precarious seed supplies have become – and as a consequence, how precarious our food security has become. Offers several learning and action resources.
