Origin & Breeding History: 'PPS05-153 B-Line', is a male fertile maintainer line of 'PPS05-153 A-Line'. It was derived by backcrossing the doubled haploid line '98-55-013' which contains the Ms8 gene to the doubled haploid line '01-120-223' in 2003. '98-55-013' was extracted from the F1 generation of the cross 97CGH406/97CGH409. '01-120-223' is a doubled haploid line extracted from the F1 generation of the cross 00NN100821/99NN018217. 'PPS05-153 B-Line' was selected in 2004 on the basis of its performance, height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, and glucosinolates content.

Tests & Trials: Trials were conducted during the summers of 2006 and 2007 in Saskatoon, Saskatchewan. Plots consisted of 3 rows, with a row spacing of 50 centimeters and a row length of 6 meters. There were two replicates arranged in a RCB design.


Comparison tables for 'PPS05-153 B-Line' with reference varieties 'PPS02-144 B-Line', 'PPS03-149 B-Line', 'PPS01-140 B-Line' and 'Ebony'
