UC Davis professors, Jorge Dubcovsky of plant sciences and Jan Dvorak of agronomy and range science, examine wheat in a campus field.

Jorge Dubcovsky, Ph.D., a worldrenowned plant geneticist who leads the UC Davis wheat breeding program, develops genetic resources for improving the yield, disease-resistance and nutritional value of wheat — one of the most widely grown cereal crops on the planet. Global demand for wheat continues to increase dramatically, up nearly 20% from just ten years ago (U.S. Wheat Associates Annual Report).

Wheat is a vital part of the farming economy in California, grown from the Imperial Valley in the south to the Klamath Basin in the north, and from the inland valleys to the coastal agricultural regions. Due to California’s large size and diverse climate, wheat can be planted for harvest in both the fall and spring seasons, depending on the region. Dubcovsky’s ground-breaking work has enabled researchers and breeders around the world to accelerate the development of more nutritious and better-adapted wheat varieties.

Dubcovsky and his team have released eleven distinct UC wheat varieties, each protected by InnovationAccess under U.S. Plant Variety Protection, and licensed to 30 commercial entities.

Consistent with the land-grant mission of UC Davis, wheat varieties released out of Dubcovsky’s breeding program are licensed only to the California wheat industry during the first three years following release, effectively providing an economic advantage for the state. InnovationAccess works closely with the California Wheat Commission in setting up licensing arrangements. After this initial three-year period, licensing is opened to other geographical areas beyond California.

This year, Dubcovsky’s lab released the ‘Yurok’ wheat variety (UC Case 2016-066), a semi-dwarf Hard Red Spring variety, which offers a high-yielding plant and a resulting grain with high protein content and excellent bread-making quality. This variety is resistant to current races of stripe rust disease and is well adapted to the Sacramento, San Joaquin and Imperial Valleys in California.
