I grow promiscuously-pollinated (PP) genetically-diverse public-domain landrace vegetable seeds for use on my farm. To maintain genetic vitality I have to grow lots more seed than I can use. The extras are available for swap. These are great seeds for breeding your own vegetable varieties, or for an emergency seed stash.

A landrace is a food crop with lots of genetic biodiversity which tends to produce stable yields under marginal growing conditions. Landrace crops are adaptively selected for reliability in tough conditions. The arrival of new pests, new diseases, or changes in cultural practices or in the environment may harm some individuals in a landrace population, but with so much diversity many plants are likely to do well under the changing conditions.

In the case of mostly self-pollinating plants like peppers, tomatoes, beans, wheat, and peas a land-race may be thought of as many distinct varieties growing side by side. They are grown and saved as a group rather than as individual cultivars.

In the case of out-crossing plants like cantaloupe, squash, or corn, a land-race can be thought of as a promiscuously pollinated population with tremendous genetic diversity. Many of the seeds in an out-crossing land-race end up being unique F1 hybrids.
