When selecting seeds for the garden or farm, it’s important to know the language. Often times, definitions of “heirloom”,  “hybrid” and GMO get confused. To avoid confusion and to help in your seed selection, we’ve provided definitions for some of these terms:

Hybrid

Hybridization is a natural process. Often times an insect or bee pollinates a plant with two parents. The result is a plant that has different characteristics than either of its parent plants.

Breeders have adopted this practice and will intentionally cross-pollinate two varieties of a plant. This process is carefully controlled so that plants achieve the best combination of characteristics. Sometimes, achieving the right set of characteristics can take years.

For example, a breeder (or grower) may be interested in a plant that has an increased size or is more resistant to disease. To achieve this, breeders will select parents that will potentially contribute a quality to their offspring, such as uniformity. This process can be repeated until the desired characteristic is achieved.

But hybrid seeds can still be produced organically. Being a hybrid does not mean that a plant is genetically modified at the cellular level. Hybrid seeds still have drawbacks, however.

In order to create a hybrid variety, the parents must be crossed each time to create the same combination of characteristics. So, hybrid seeds do not “reproduce true,” which means that plants grown from seeds (i.e., the second generation) may or may not share the desired characteristics selected from the first generation.

If it is a true hybrid, the process remains natural. But you do have to rely on seed companies, because the seeds you save are not likely to produce the same results.

To advertise and legally sell a hybrid product, the parent plants must be identified and the pollination controlled. Hybrid seeds generally cost more but will not produce consistent characteristics after the first generation.

Open Pollinated

Many vegetable varieties are open pollinated. Open pollination occurs in one of two ways: cross-pollination or self-pollination.

Reproduction by cross pollination occurs between two plants when insects, wind or water facilitate the pollination process. Beets, brassicas, carrots, corn and squash are all cross-pollinating vegetables. To keep the varieties true in pollination, these vegetables are often kept in isolation in the field.

Self-pollination occurs when the male and female reproductive parts are contained within the same plant and can therefore initiate pollination without travel. Beans, lettuce, peas and tomatoes are self-pollinated vegetables and do not require isolation in the field like cross-pollinated vegetables. These varieties are also the easiest for growers who want to save seeds from year to year.

Open pollination is different from hybridization because it does not involve human intervention. As a result, open-pollination is often considered more natural.

Heirloom

The definition for heirloom plant varieties is less clear. Generally, when a plant is grown from seed, only open-pollinated varieties are considered heirloom. Unlike the hybrid types, open-pollinated seeds will display most of the same characteristics as the parent plant.

Heirlooms varieties are preserved by growers who save seeds from year to year to preserve a desirable trait. Some heirlooms are past down from one generation to the next, and some experts say an heirloom must be at least 50 years old.

Heirloom varieties often produce different shapes, colors and flavors, but heirloom growers also know these plants tend to vary in size.

GMO

Unlike hybrid seeds, GMO seeds are not created using traditional breeding methods. Instead, GMO seed varieties are created using high-tech solutions in the lab, and include the complicated processes of genetic engineering, often extracting material from one type of plant and inserting it into another type of plan. The inserted genetic material can provide a desirable trait such as resistance to a disease or increased vigor. GMO crops most used in the U.S. are soybean and corn. They have been engineered for increased vigor but also resistance to glyphosate, a broad-spectrum herbicide. Due to excessive use of glyphosate there are economically important weeds that are now resistant to this herbicide.

GMO corn often includes a “B.T. gene” which stand for bacillus thuringiensis to prevent larvae from feeding on the crop. The B. thuringiensis is a natural bacteria but when inserted into a crop that crop is a GMO crop, which is not permitted in organic production systems.

GMO stands for “genetically modified organism,” which means that a plant’s DNA is altered in a way that does not exist in nature. A genetically modified organism will have different DNA than its parent.

Sometimes scientists will also insert the genes of another plant or variety to change the way a plant reacts to its environment.

Plant GMOs are regulated by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service under the Plant Protection Act. The form of regulation varies depending on the type of GMO involved.
