Former UC Foothill Experiment Station in Jackson, California |
| Comments |
This selection came to Foundation Plant Services in 1965 from University of California's former Foothill Experiment Station in Jackson, Amador County, California. The plant material was at location K8v6 at the station under the name(s) Johannisberger Riesling or Chauche gris. It originally came from the former experiment station at Berkeley in 1889 and was planted in that year at the Foothill Station. When the plant material arrived at FPS in 1965, it was given the name Grey Riesling FPS 07. The name was changed from Gray Rielsing FPS 07 to Trousseau gris FPS 07 in 2003. DNA tests conducted at FPS showed that this selection matched references for Trousseau gris, not for Riesling. |
