Origin & Breeding History: 'SWH5263RR' was developed by Svalöf Weibull AB, Svalöv, Sweden from a cross made in 1997. 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 SWH5263RR. This line was tested for yield, oil content, glucosinolate content, stalk stiffness, blackleg tolerance and maturity.
