QUALITY CHARACTERISTICS: erucic acids 0.04 % of total fatty acids, very low glucosinolates

Origin & Breeding History: 'NR02-5659' was developed from a cross made in 2002 in Saskatoon, Saskatchewan. An F1 plant derived from this cross was used as a donor plant to produce microspore derived doubled haploids in 2002. From this population of doubled haploids, one doubled haploid line was selected and designated 'NR02-5659'. All subsequent generations of 'NR02-5659' were derived from this selected plant. Selection criteria included resistance to Roundup, maturity, lodging resistance, seed quality and yield. Yield trials were conducted in 2004-2006 with concurrent trials run for herbicide resistance. Disease testing was conducted in 2005 and 2006.

Tests & Trials: Tests and trials were conducted during the summers of 2006 and 2007 in Rosthern, Saskatchewan. Plots consisted of 6 rows, with a row spacing of 20cm and a row length of 5.5 meters. There were 4 replicates arranged in an RCB design.


Comparison tables for 'NR02-5659' with reference varieties 'SP Banner', 'SP Armada' and '9550'

Means are based on a two year average of 30 measurements for plant height and 60 for silique, beak and pedicel characteristics. Differences are significant at the 2% probability level based on LSD values.
