Century-Old Barley Experiment Tracks Crop Adaptation

A $1.7 million NSF award funds research on how barley genes adapt as weather becomes more extreme, a line of work still in its early stages.

Century-Old Barley Experiment Tracks Crop Adaptation

Live Poll

Should the government fund more research to help crops adapt to climate change?

UC-Riverside geneticist Daniel Koenig has received a $1.7 million National Science Foundation CAREER Award to study how barley adapts to its environment. The work is research-stage: it uses a 1920s breeding experiment and is not a product or established result.

Why it matters

Barley is the fourth most produced cereal in the world and has been grown as a crop for more than 10,000 years, spreading into environments from hot, dry Egypt to cold, wet Minnesota. Understanding which genes let it adapt may help guide its future as weather becomes more extreme.

The project relies on a grant of $1.7 million and on barley varieties collected worldwide and grown in Davis, Calif., and Bozeman, Mont., since the 1920s. Because barley produces only one generation per year, changes in the crop can be observed only slowly, and the research has not yet reported measured genetic results.

The players

University of California-Riverside

A public research university whose Department of Botany and Plant Sciences hosts plant genetics research, including Koenig's barley adaptation work.

National Science Foundation

The U.S. federal agency that funds basic research, and that awarded the $1.7 million CAREER Award supporting Koenig's study.

Daniel Koenig

An assistant professor of botany and plant sciences at UC-Riverside whose lab studies the genetic basis of barley adaptation.

The details

Koenig's lab is analyzing the genes of barley varieties from a 1920s-era experiment and watching them continue to adapt. The project will compare genes from the start of that experiment with genes from today, using traditional molecular biology (techniques for studying DNA and gene activity directly) and computational methods that analyze the resulting data. The same process of identifying survival genes could be repeated for other crops.

Barley was domesticated as a crop over 10,000 years ago.
Breeders began the barley variety experiment in Davis, Calif., and Bozeman, Mont., in the 1920s.
The NSF CAREER Award to Koenig was reported on November 3, 2026.

The Tech Race

Barley is the fourth most produced cereal in the world, so its adaptation genetics bear on a major crop system. The project's approach of tracing decades of barley varieties from the 1920s onward is a research trajectory rather than a commercial race, and the extraction does not name competing efforts.

This is an early-stage research grant, so no barley-related product or crop change is available yet. Any practical effect on crop varieties would depend on results and a timeline the extraction does not provide.

The takeaway

Watch for the first published results comparing 1920s-era barley genes with modern ones, which would show whether the survival genes Koenig's team identifies hold up. Because only one barley generation grows per year, progress will be measured across seasons rather than quickly.
