GMO vs Non-GMO Seeds: A Simple Explanation.

Introduction

Walk into any seed conversation and you’ll quickly encounter the term GMO. For greenhouse growers, understanding what GMO means — and what it doesn’t mean — is important for communicating with customers, navigating certifications, and making informed variety decisions. This guide breaks it down clearly, with context from the Paramount Seeds catalog.

What Is a GMO Seed?

A Genetically Modified Organism (GMO) seed has been altered using biotechnology — specifically, by inserting, deleting, or modifying genes in a way that does not occur naturally through conventional breeding or hybridization. This is done in a laboratory using techniques such as CRISPR gene editing or recombinant DNA technology.

The goal is typically to introduce a specific trait that would be difficult or impossible to achieve through traditional breeding — such as resistance to a particular herbicide, insect pest, or disease.

Common Examples of GMO Crops (Field/Commodity Crops)

• Bt Corn — engineered to produce a protein toxic to certain insects, reducing insecticide use.
• Roundup Ready Soybeans — modified to tolerate glyphosate herbicide.
• Virus-resistant Papaya (Rainbow Papaya) — developed to resist Papaya Ringspot Virus.

Are There GMO Greenhouse Vegetables?

In commercial greenhouse vegetable production, GMO varieties are not commercially available to growers in North America or Europe. All greenhouse vegetable seeds sold by Paramount Seeds are Non-GMO — disease resistance and performance traits are achieved entirely through conventional and hybrid breeding. This is an important point for growers to communicate to their customers: greenhouse-grown tomatoes, cucumbers, and peppers are Non-GMO by default.
