Fact Sheet
The top variety for "AR"-mixtures
DUS test conducted at Scharnhorst, BSA (DE), 2010-2012
UPOV No Characteristics State of expression Note
Alike the varieties Salmo and Arcturus, Algira originates from a colchicine treatment to transform diploid elite breeding material tracing back to Swiss ecotypes into the tetraploid state. Algira shows an early heading as the variety Arvicola an can be used in "AR"- mixtures. Compared to Arvicola and Artesia, Algira shows a largely improved yield and resistance against crown rust. Also with regard to
digestibility, Algira showed top results in the official trials from 2009 to 2011.
This is also why Algira got the best overall ranking among all candidates and varieties tested in the official trials.
