Sorghum is not only a potential drought-tolerant crop for the San Joaquin Valley, it also presents the opportunity for scientists to understand the mechanism behind drought tolerance at the genetic level, said UCCE sorghum specialist Jeff Dahlberg in a recent segment on Fresno's ABC 30 Action News.

Reporter Cristina Davies spent an hour and a half at the UC Kearney Agricultural Research and Extension Center in Parlier during the sorghum harvest to learn about the potential of sorghum research. 

"If we can elucidate the genetics behind (drought tolerance), what we believe is we can use those genetics to see if the genetics are available in corn, or in rice, or in wheat," Dahlberg said. "I think the genes may be there. We just don't have the tools yet to search for the genes in those crops."

Conducting drought-tolerance research in California is ideal because the summer is typically devoid of rain. Researchers can control exactly how much water is applied to each sorghum plot. The research has revealed more than 100 genetic markers that may confer drought tolerance.

"We've been really thrilled with the data that's been coming out of this. Like most research, we are learning so many things we don't understand," Dahlberg said.

The research is being conducted in collaboration with the USDA's Agricultural Research Service research center, which is across the street from Kearney. USDA research scientist Devin Coleman-Derr was present for the sorghum harvest.

"Like humans take probiotics, there may be a use for microbes in sort of promoting better and better yields in the field," Coleman-Derr said.
