Wheat Scoop: Wheat Foods Council Video Shows How Wheat Has Changed in 100 Years

Amber waves of grain are an iconic landscape, but that does not mean today’s varieties are exactly the same as the wheat fields harvested when Katharine Lee Bates penned the lyrics to America the Beautiful.

So, what’s different about modern wheat varieties?

According to a Wheat Scoops report by Kansas Wheat, the Wheat Foods Council tackled this question in the second episode in its new series of short videos featuring wheat expert Brett Carver, wheat genetics chair in agriculture at Oklahoma State University, available now.

Long Lineage

Wheat has been cultivated for nearly 10,000 years, linked to the ancient grains einkorn and emmer.

The lineage of these grains still exists, but centuries of selective wheat breeding established wheat as the cereal crop we know today.

In the 20th century, researchers really started to unlock the potential of the wheat genome to benefit farmers and their global consumers.

“We use that century mark because wheat breeding really got its beginnings in the United States, including Oklahoma, in the 1920s,” Carver explains in the video.

Since that time, wheat breeders like Carver have used the genes that already exist in wheat to help select varieties with specific traits that allow the plant to be more resilient and a better producer of grain.

Short Story

For example, agronomist and humanitarian Norman Borlaug bred wheat that was shorter — and stronger — than other varieties at the time.

Known as dwarf wheat, these plants were shorter, but stood straight in the fields, even during gusty days.

“We have a plant that today is a little bit shorter than it was 100 years ago,” Carver says, “and most importantly, it has stronger straw so it can withstand the winds that we see in the Great Plains and elsewhere in the country.”

This work by Borlaug kickstarted the “Green Revolution,” which led to wheat varieties that focused energy on grain production, rather than plant height.

Borlaug’s wheat was credited with saving more than a billion lives and earned him a Nobel Peace Prize.

Tougher Crop

Since that time, wheat researchers have continued Borlaug’s legacy by continually seeking out varieties with more naturally occurring disease resistance, drought tolerance and many other factors that increase productivity.

“Greater resilience — and this is part of doing more with less,” Carver says.

“So, it can take cold, it can take heat, it can take drought, it can take stresses from diseases a lot better than that wheat we had 100 years ago.”

Overall, wheat breeding over the past century has resulted in golden arches of wheat that help feed the world, all while using the less land and resources to do so.

“The wheat today is a tougher plant and can do more with less — that about sums it up,” Carver says.

“In other words, we're trying to produce more food, more grain than we did 100 years ago with less land area to do it with.

"That's the challenge we're going to keep facing as we move forward, as our population grows and our land area for crop production diminishes.

"So, we have to improve productivity.”
