Origin & Breeding History: 'PPS04-207' is a restorer line in the process of F1 hybrid production. It was derived as a doubled haploid line 01-138-065 containing the Rf3 gene in homozygous state from a cross made in Canada in 2001 and doubled haploid extraction in 2002. The pedigree is as follows: 00NN101109 / 98NN101159 'PPS04-207' was selected in 2003, on the basis of fertility restoration and expression of tolerance to glufosinate ammonium herbicide. Other selection criteria were height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content and combining ability.
Tests & Trials: Test and trials were conducted in Saskatoon, Saskatchewan during the summers of 2004 and 2005. Plots consisted of 3 rows that were spaced 50 cm apart with a row length of 6 meters. There were two replicates arranged in a RCB design.
Comparison tables for 'PPS04-207' with reference varieties 'PPS98-274', 'PPS02-364' and 'Ebony'
Means are based on a two year average of 60 plant parts for silique, 60 for leaf and petal characteristics, 60 for height and 60 cotyledon measurements. Differences are significant at the 2% probability level based on LSD values.
