Origin & Breeding History: 'Sorento' (experimental designations Ceb 4163, 98075-135) is the result of the cross 97122 x 97147 made during 1998 in Lelystad, The Netherlands, where 97122 = 91043-516 x Agadir; 97147 = Eclipse x Agadir; 91403-516 is Ceb 1136 x Baccara; and Ceb 1136 = Solara x {(Flavanda x Progreta) x Flavanda}. A single plant was selected by pedigree selection method, followed by single seed descent to the F4 generation. The F4 generation was screened for resistance to powdery mildew in 2001. Yield trials were conducted during the F5-F7 generations in years 2002-2004. The variety was also tested for stiffness and straw strength in the F4 to F7 generations. One line was bulked in the F7 generation to form this variety.

Tests & Trials: Tests and trials for 'Sorento' were conducted in Westlock, Alberta in 2006 and Barrhead, Alberta in 2007. The candidate and reference varieties were seeded in a 4 replicate randomized complete block design. Each plot consisted of 4 rows per variety, spaced at 20 cm. The plots were seeded to 6 metres and trimmed to 4 metres. Measured observations were based on 20 measurements.
