FR (Representative: Semences Vertes) Fact Sheet
DUS test conducted at Scharnhorst, BSA (DE), 2013-2015
UPOV No Characteristics State of expression Note
Source of the late maturity of Vidalia is a tetraploid population that showed very good persistence in the region of Les Barges (VD, Switzerland), previously thought to be an ecotype. Vidalia was created by crossing this population with early maturing material of the type Arcturus/Algira/Salmo and shows 1 day later heading than Alligator, Compared to Alligator, Vidalia shows a largely improved resistance against leaf diseases, competitive ability and persistence. In the official trials from 2009 to 2011, Vidalia showed best digestibility among all candidates and varieties tested.
