DISEASE RESISTANCE: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and resistant to White Rust (Albugo candida, races 7a & 2v)

Origin & Breeding History: 'PPS07-289' is a low linolenic restorer line in the process of F1 hybrid production. It was derived as a doubled haploid containing the Rf3 gene in homozygous state. The initial cross occurred in 2004 in Canada with the double haploid extraction occurring in 2004/2005. 'PPS07-289' was selected in 2006 and 2007 on the basis of fertility restoration and expression of tolerance to glufosinate ammonium herbicides. Other selection criteria included linolenic acid content, height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content and combining ability.

Tests & Trials: Tests and trials were conducted during the summers of 2007 and 2008 in Saskatoon, Saskatchewan. Plots consisted of 3 rows, with a row length of 6 metres and a row spacing of 40 cm. There were 2 replicates arranged in a RCB design.


Comparison tables for 'PPS07-289' with reference varieties 'PPS98-274', 'PPS02-364' and '5030'

Means are based on a two year average of 60 plant parts for leaf, petiole, silique, beak and pedicel characteristics. Differences are significant at the 2% probability level based on LSD values.
