The pedigree of 'PPS97-126' is PGS 94CGH070 x PGS 94CGH073. 'PPS97-126' was developed by the pedigree method. 'PPS97-126' was selected in 1996 on the basis of male sterility expression and tolerance to glufosinate ammonium herbicide. Additional selection criteria were height, vigour, maturity, oil content, fatty acid profile, glucosinolate content and combining ability.

Tests & Trials: Tests and trials of 'PPS97-126 B-line' 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.
