Varieties used for comparison: 'Arid', 'Dahinda' and 'Davin'
Summary: '8571' is resistant to imidazolinone herbicides whereas the reference varieties are not. The leaves of '8571' have medium to strong rugosity whereas the leaves of 'Arid' have weak to medium rugosity. The leaves of '8571' are longer than those of 'Arid' and 'Dahinda'. '8571' flowers earlier than 'Davin' and later than 'Arid' and 'Dahinda'. '8571' matures later than 'Dahinda' and earlier than 'Davin'. Plant height at maturity of '8571' is taller than that of 'Arid'.

Origin & Breeding History: '8571' is a microspore derived doubled haploid line produced from the cross 'Davin'//J04E-0044/J03Z-16440, made in 2004 by Viterra Research and Development staff in Saskatoon, Saskatchewan. Following chromosome doubling, the original DH plant was grown in a greenhouse and self-pollinated. The line was selected and designated J05Z-08376. Nursery rows were grown near Temuco, Chile in 2005-2006. Selection was based on agronomic performance, canola-quality traits and resistance to imidazolinone herbicide. '8571' was entered into a first year (private data) Co-op trial in 2006. Based on good agronomic performance and quality characteristics, it was entered a second year of registration trials in 2007.
Tests & Trials: Trials were grown during the summers of 2007 and 2008 in Watrous, Saskatchewan. Plots consisted of 5 rows with a row spacing of 22 centimeters and a row length of 1.3 meters. There were 2 replicates arranged in a RCB design.
