Editing Trebbiano (section)

==History==
Trebbiano may have originated in the Eastern Mediterranean, and was known in Italy in Roman times. A subtype was recognized in Bologna in the thirteenth century, and as Ugni blanc made its way to France, possibly during the Papal retreat to Avignon in the fourteenth century.<ref name="SLSA">{{cite web |last=Radden |first=Rosemary |title=Grapes and Wines of the World |publisher=The State Library of South Australia, GPO Box 419, Adelaide SA 5001 |url=http://www.slsa.sa.gov.au/site/page.cfm?area_id=15&nav_id=553 |access-date=2007-04-22}}</ref>

An Italian study published in 2008 using [[DNA typing]] showed a close genetic relationship between [[Garganega]] on the one hand and Trebbiano and several other grape varieties on the other hand. It is therefore possible that Garganega is one of the parents of Trebbiano; however, since the parents of Garganega have not been identified, the exact nature of the relationship could not be conclusively established.<ref>[http://www.vitis-vea.de/admin/volltext/w1%2008%20895.pdf ''‘Sangiovese’ and ‘Garganega’ are two key varieties of the Italian grapevine assortment evolution''] {{Webarchive|url=https://web.archive.org/web/20110719112637/http://www.vitis-vea.de/admin/volltext/w1%2008%20895.pdf |date=2011-07-19 }}, M.

During a series of trials between 1924 and 1930, Trebbiano was [[crossed (wine)|crossed]] with [[Gewürztraminer]] to create the pink-skinned Italian wine grape variety [[Manzoni rosa]].
