Origin & Breeding History: 'Café' was developed by Svalöf Weibull AB, Svalöv, Sweden from a cross made in 1998. Plant selection was made in the F2 for quality traits and blackleg tolerance. In subsequent generations pedigree selection was performed. One plant was finally selected and designated 'Café'. This line was tested for yield, oil content, glucosinolate content, stalk stiffness, blackleg tolerance and maturity.

Tests & Trials: Tests and trials for 'Café' were conducted during the summers of 2005 and 2006 in Aberdeen, Saskatchewan. Plots consisted of 8 rows, 4 meters in length with a row spacing of 15 cm. There were 2 replicates arranged in a Random Complete Block Design.
