Variety Description
Varieties used for comparison: 'Ebony' and '2273'
Summary: 'PPS98-274' contains the Barstar gene which provides restoration ability of male sterile lines carrying the Barnase gene in combination with resistance to glufosinate ammonium herbicide whereas 'Ebony' does not have this combination of characteristics. 'PPS98-274' has a longer silique than '2273'. The beak length of 'PPS98-274' is longer than 'Ebony'. 'PPS98-274' flowers later than '2273'. 'PPS98-274' is resistant to glufosinate ammonium herbicide while 'Ebony' is not.
Description:
'PPS98-274' is a restorer (male fertile) canola line used in the process of F1 hybrid production bearing glufosinate ammonium tolerance. The cotyledons are medium in width. Leaf blades are medium green with few to medium number of sharp lobes which are shallow in depth. 'PPS98-274' has yellow flower petals. The siliques are short to medium in length with a medium beak and pedicel length. The plants are tall in height. The seed colour is black. There are trace amounts of erucic acid and low glucosinolates.
Origin & Breeding History: The pedigree of 'PPS98-274' is PGS 1863//PGS1671/PGS1112. 'PPS98-274' is a restorer line derived as a doubled haploid line 96-13-269. The crosses and DH line extraction were made in Canada in 1996 subsequently to a transformation program at the facilities of Plant Genetic Systems N.V. of Ghent, Belgium. 'PPS98-274' was selected in 1997 on the basis of fertility restoration of numerous male sterile lines and expression of tolerance to glufosinate ammonium herbicide. Additional selection criteria were height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content and combining ability. Breeder seed production commenced in the 1998 season.
Tests & Trials: Tests and trials of 'PPS98-274' were conducted at Saskatoon, Saskatchewan during the summers of 2000 and 2001. Trials were arranged in 2 replicates which were randomized with each plot measuring 6 metres x 1.5 metres with 3 rows per plot.
