Seed saving

To be successful at seed saving, new skills need to be developed to ensure that desired characteristics are retained in the landraces of the plant variety. Important considerations are the separation distance needed from plants of the same species to ensure that cross-pollination with another variety does not occur, and the minimum number of plants to be grown which will preserve inherent genetic diversity. It is also necessary to recognize the preferred characteristics of the cultivar being grown so that plants that are not breeding true are selected against, and to understand the breeding of improvements to the cultivar. Diseases that are seed-borne must be recognized so that they can be eliminated. Seed storage methods must be good enough to maintain viability of the seed. Germination requirements must be known so that periodic tests can be made. Care must be taken, as training materials regarding seed production, cleaning, storage, and maintenance often focus on making landraces more uniform, distinct and stable (usually for commercial application) which can result in the loss of valuable adaptive traits unique to local varieties. Additionally, there is a matter of localized nature to be considered. In the upper northern hemisphere, and lower southern, one sees a seasonal change in terms of a cooler winter. Many plants go to seed and then go dormant. These seeds must hibernate until their respective spring season. ==Open pollination==

Open pollination is an important aspect of seed saving. Plants that reproduce through natural means tend to adapt to local conditions over time, and evolve as reliable performers, particularly in their localities, known as landraces or "folk varieties." ==Legality==

While saving seed and even exchanging seed with other farmers for biodiversity purposes has been a traditional practice, these practices have become, at least in some cases, illegal for the plant varieties that are patented or otherwise owned by some entity (often a corporation). In 2013 Bowman v. Monsanto Co. established that it was patent infringement for farmers to save crop seeds (soybeans in that case) and grow subsequent crops from them, if the seeds or plants were patented. Seed corporations are able to earn massive profits from this control over commercial seed supplies, and consequently further loss of control has been taken from US farmers over their farm production process. ==Seed sovereignty==

Seed sovereignty can be defined as the right "to breed and exchange diverse open-sourced seeds." It focuses largely on the rights of individuals to be able to save seed, and be independent from major seed companies. Seed sovereignty activists point to seed saving as an important practice in building food security, as well as restoring agricultural biodiversity. Activists also draw attention to the cultural importance of seed saving practices, especially their role in maintaining traditional plant varieties. It is closely connected to the food sovereignty movement and food justice movement. ==See also==
