Variety Description

Varieties used for comparison: 'PPS02-144 A-Line', 'PPS03-149 A-Line', 'PPS01-140 A-Line' and 'Ebony'

Summary: 'PPS05-153 A-Line' has a narrower cotyledon than 'PPS03-149 A-Line', a wider cotyledon than 'PPS01-140 A-Line' and 'Ebony', and a slightly wider cotyledon than 'PPS02-144 A-Line'. The cotyledon length of 'PPS05-153 A-Line' is shorter than that of 'PPS03-149 A-Line', longer than that 'PPS01-140 A-Line' and slightly longer than that of 'Ebony'. 'PPS05-153 A-Line' has sharper and deeper leaf margin indentations than 'PPS01-140 A-Line' and 'PPS03-149 A-Line'. 'PPS05-153 A-Line' begins flowering earlier than 'PPS01-140 A-Line'. The silique attitude of 'PPS05-153 A-Line' is horizontal while it is semi-erect for 'PPS03-149 A-Line' and 'Ebony'. 'PPS05-153 A-Line' has a longer silique than 'PPS01-140 A-Line'. The beak of 'PPS05-153 A-Line' is longer than that of 'PPS01-140 A-Line'. 'PPS05-153 A-Line' has a broader silique than 'Ebony'. 'PPS05-153 A-Line' is more resistant to lodging than 'PPS01-140 A-Line', 'PPS02-144 A-Line' and 'PPS03-149 A-Line'. 'PPS05-153 A-Line' contains higher levels of glucosinolates than 'PPS01-140 A-Line' and 'PPS03-149 A-Line'. 'PPS05-153 A-Line' has resistance to glufosinate ammonium herbicides while 'Ebony' does not. 'PPS05-153 A-Line' has better resistance to Blackleg than 'PPS02-144 A-Line'. The anthers of 'PPS05-153 A-Line' are sterile while those of 'Ebony' are fertile.

Origin & Breeding History: 'PPS05-153 A-Line' is a male sterile line containing the Ms8 gene construct in the heterozygous state. 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 A-Line' was selected in 2004 on the basis of its male sterility stability, expression of tolerance to glufosinate-ammonium herbicide, good combining ability, 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 A-Line' with reference varieties 'PPS02-144 A-Line', 'PPS03-149 A-Line', 'PPS01-140 A-Line' and 'Ebony'

Means are based on a two year average of 60 plant parts for silique measurements, 60 for leaf and petal characteristics, 30 for height and 40 cotyledon measurements. Differences are significant at the 2% probability level based on LSD values.
