GMO, Hybrid, and Heirloom Seeds

What is the difference between a GMO seed and a Heirloom Seed? What is an Heirloom seed?

GMO Seeds

Genetically Modified Organism (GMO)

A GMO is any organism whose genetic make up has been modified/altered in a laboratory using genetic engineering methods in such a way that it does not occur naturally in any natural combination. This also includes seeds.

Hybrid Seeds

Hybrid plants are made by crossing selected inbred strains with one another. While they produce fast, easy, predictable, uniformed, and higher yield crops, the seeds are often sterile or transmit certain diseases which prevents the new seeds from being saved post harvest. Heirloom seeds are seeds that can be saved.

Heirloom Seeds

Seeds that are passed down from generations, preserving the genetic heritage of the plant. Variety vintages are at least 50 years old, but some are much older. Heirloom varieties are open-pollinated, breed true-to-type, and can be either organic or non-organic. Heirloom seeds can also be saved and grown from harvested plants, unlike GMO seeds in which new seeds must be purchased after harvest in order to plant more.
