DISEASE RESISTANCE: resistant to moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam), moderately resistant to moderately susceptible to White Rust (Albugo candida, race 2A) and moderately susceptible to susceptible to White Rust (Albugo candida, race 2V)

Origin & Breeding History: 'Estlin' is a microspore derived doubled haploid line produced from the cross J00D-01922 / Arid, made in 2001 by Saskatchewan Wheat Pool (SWP) staff in Saskatoon, Saskatchewan. J00D-01922 is an experimental line developed by SWP. Arid is a canola quality Brassica juncea variety registered in 2002. Following chromosome doubling, the original DH plant was grown in a greenhouse and self-pollinated. The line was designated J02D-05171. Nursery rows were grown near Temuco, Chile in 2002-2003. Selection was based on agronomic performance and canola-quality traits. J02D-05171 was entered into a first year (private data) Co-op trial in 2003. Based on good agronomic performance and quality characteristics, J02D-05171 entered a second year of registration trials in 2004.

Tests & Trials: Trials were grown during the summers of 2004, 2005 in Watrous, Saskatchewan. Plots consisted of 4 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.
