Growing the Future: How Hybrid Seeds are Shaping Modern Agriculture

As populations have grown, the agriculture industry has embraced science and technology to accommodate the increase in commercial and food demands. The development of hybrid seeds provided a much-needed bump to crop yields, but innovations in genetics offer additional benefits.

A Brief History of Hybrid Seed

Today’s preference for hybrid seeds resulted from several historical events that drove American researchers to seek better yields. During the early 20th century, farmers relied on open-pollination for corn production. Corn shows were a popular way to showcase varieties, but the corn was judged primarily on appearance. The goal was an attractive, uniform crop that was easy for hand-picking. Yield potential and suitability for environmental conditions hardly factored in.

Researchers in the northeast began experimenting with self-pollination and developed inbred lines. Noticing that the inbreeding created less vigorous plants than hybrids, the researchers suggested double-cross hybrids as the best way to improve crops. 

The use of double-cross hybrid seed took off in the 1930s/1940s. A series of droughts, the Great Depression, and World War II drove farmers to look for higher yields, better stress tolerance, and less reliance on hand-picking crops. While yields improved, it was the switch to single-cross hybrids in the ’60s that truly boosted corn production.

Innovations in Hybrid Seed Production

Some of the most effective and controversial innovations in agriculture center around DNA and gene editing. Before these technologies, hybrid seed production solely relied on breeding to transfer desired traits. However, researchers found that making changes to the DNA allowed them more control over the process and made a larger variety of traits possible. 

Hybrid Seeds: Genetic Engineering vs. Gene Editing

Genetic engineering involves the transfer of DNA from one organism to another. This foreign DNA may be from another plant or an unrelated organism. In either case, the incorporated DNA becomes part of the receiving organism’s DNA and can be replicated by its RNA. This process requires rigorous testing to ensure that the foreign DNA does not create a hazard to the public. 

An example of how genetic engineering can be used in hybrid seed production is insect resistance from Bacillus thuringiensis. If a microorganism is naturally resistant to insects, scientists can isolate and transfer that gene from the microorganism to the crop. The DNA is replicated as part of its own, and the resulting seed now includes that insect resistance.

Gene editing is simpler than genetic engineering in that foreign DNA is not transferred. Scientists locate the DNA code they wish to alter and make changes directly. Gene editing can be used to alter gene expression, like an on/off switch or volume control. CRISPR is the form discussed most often, but it is not the only method of editing DNA.

RNAi Technology

RNA interference (RNAi) is a naturally occurring regulatory system that deactivates genes. Research has focused on its use in controlling disease and infection, but some seed producers use it as well. For instance, the RNAi technology that Bayer uses for insect resistance interferes with the production of a specific protein that the western corn rootworm needs to survive.

Benefits to Modern Agriculture

The development of hybrid seeds and the more recent innovations with DNA have shaped modern agriculture, contributing to food security and sustainability. 

Increased Yield

To say that hybrid seeds were paradigm-shifting is an understatement. There was little change in corn yields until the 1930s. With the increased interest in hybrid seed, yields increased between 400-500% from the 1930s to the early 2000s, a massive improvement that allows modern farmers to supply food and materials to a growing population.  

Environmental Factors

Breeding for drought and heat resistance are just two examples of how hybrid seed has changed modern farming practices. Water is a finite resource. Crops that are better able to handle their environment require less irrigation or are able to use water more efficiently to sustain themselves and still produce a decent yield. 

Pest Control

A better yield means nothing if it is only feeding insects or detrimental microorganisms. In the past, the only real way to manage pests and weeds on a large scale was chemical-based. Gene technologies create resistant crops and reduce the need for applying potentially harmful chemicals that make their way into the environment.
