Comments	Riesling Italico (syn. Welschriesling) is a white grape variety grown widely in Central and Eastern Europe. Known as Olasrizling in Hungary, the cultivar is the most planted grapevine. The cultivar is the most planted white wine grape in Croatia, where it is known as Grašvina. The true Riesling is known in Italy as Riesling renano. There is another grape cultivar in Italy with the name ‘Riesling’, which is genetically unrelated to the ‘true Riesling’ (Riesling renano). Riesling Italico has characteristically different morphology and produces distinctly different wine than Riesling renano.

Riesling Italico Selections

Information about: Clonal Families, Selection Numbers and Registration Status

	Riesling Italico [04]
Registration Status	Registered
Source	Walsch Riesling FPS 01, which was from Jackson, California
Comments	This selection came from plant material that was once planted in the vineyards of University of California's Foothill Experiment Station in Jackson, California (location N24). The material came to Foundation Plant Services around 1965 and was planted in the foundation vineyard in 1967 under the name Walsch Riesling FPS 01. The selection tested positive for leafroll virus in the 1990's and underwent microshoot tip tissue culture disease elimination therapy in 1997. The name was changed in 1996 from Walsch Riesling to the more-correct Riesling Italico. After the treated plant material successfully completed disease testing, the selection was released with a new selection number, Riesling Italico 04. Riesling Italico 04 successfully completed testing to qualify for the Russell Ranch Foundation Vineyard in 2013.
	Riesling Italico [05]
Registration Status	Registered
Source	Hungary
Comments	Riesling Italico 05 was donated to the Foundation Plant Services public collection in 2003 by Dr. Laszlo Kocsis, Georgikon Faculty, Department of Horticulture, University of Veszprem, Hungary. The plant material was originally named Italian Riesling, but the name was changed in 2010 to reflect the correct prime name for this variety. The original material was infected with virus and underwent microshoot tip tissue culture disease elimination therapy at FPS in 2007. The treated plant material successfully completed testing for the California Grapevine Registration & Certification Program and was planted in the FPS Classic Foundation Vineyard in 2011. Riesling Italico 05 successfully completed testing under the 2010 Protocol and was planted in the Russell Ranch Foundation Vineyard in 2012 as Riesling Italico 05.1.
