Origin & Breeding History: 'Triactor' (experimental designation SW 032202) was developed by Svalöf Weibull AB, Svalöv, Sweden. The variety originates from the cross made in 1997 of SW 9619019 x 'Stork' . A single plant was selected in the F4 generation using the modified pedigree method based on the selection criteria of disease resistance, grain quality and later yield, straw stiffness and other agronomic characters.
Tests & Trials: Trials were conducted during the summers of 2006 and 2007 in Saskatoon, Saskatchewan. Plots consisted of 5 rows, with a row spacing of 15 cm and a row length of 5 meters. There were 3 replications arranged in a RCB design.
