Quick Answer
Yes, it is possible to save seeds from GMO plants, but the process can be challenging and may require careful consideration of the plant's genetic makeup and seed characteristics.
Seed Types and Viability
Saving seeds from GMO plants can be complicated due to the unique genetic modifications. Typically, open-pollinated (OP) plants are ideal for seed saving as they produce seeds that are true to type and can be saved and replanted with minimal degradation. However, many GMO plants are developed from hybrid seed, which can be more difficult to save due to reduced viability. For example, some GMO corn varieties have shown a 50-70% reduction in seed viability after one generation.
Isolation and Storage
When saving seeds from GMO plants, it’s essential to isolate the seed production area from other plants to prevent cross-pollination and contamination. This can be achieved by using physical barriers, such as row covers or screens, and maintaining a distance of at least 1-2 miles (1.6-3.2 kilometers) between the GMO plant and other open-pollinated varieties. Proper storage of the saved seeds is also crucial, with ideal conditions including a cool, dry place with a consistent temperature between 32-40°F (0-4°C) and a relative humidity of 30-50%.
Seed Treatment and Testing
Before saving seeds from GMO plants, it’s recommended to treat the seeds with a bleach solution (10% bleach to 90% water) to reduce the risk of fungal contamination. Additionally, testing the seeds for viability and germination rates can help ensure the quality of the saved seeds. This can be done by planting a portion of the seeds in a controlled environment and monitoring their growth and germination rates.
