A Ray of (Sweet) Hope for the Citrus Industry

There’s a little good news coming out of Florida’s citrus world—and let’s be honest, we could use some. Since citrus greening disease showed up in 2005, the state has lost about 90% of its citrus production. But researchers with USDA’s Agricultural Research Service may have found a bright spot.

At a research farm in Groveland, Florida, scientists took a closer look at a sweet orange tree called “Donaldson.” Despite being surrounded by trees that were struggling—or already dead—this tree was thriving. It’s part of a USDA variety collection that goes back more than 100 years.

Donaldson isn’t a new tree—it was planted over 30 years ago, right alongside the more familiar Hamlin orange. While Hamlin has taken a beating from citrus greening, Donaldson has held strong. And here’s the kicker: it makes great-tasting juice, too.

Researchers say it could be a solid option for commercial juice production, especially early in the season. Taste tests showed promise, and more field trials are underway. Scientists will also be digging into what’s giving this tree its edge.
