Variety Description

Varieties used for comparison: 'CDC Bethune', 'CDC Sorrel' and 'Hanley'

Summary: The plants of 'Shape' are shorter than those of 'CDC Sorrel'. The stigma colour of 'Shape' is pale violet whereas it is white for 'CDC Sorrel'. 'Shape' matures earlier than 'CDC Sorrel' but later than 'Hanley'. The ciliation of the false septa is absent in 'Shape' whereas it is present in 'CDC Sorrel' and 'Hanley'. The seeds of 'Shape' have a higher oil content than those of the reference varieties. The oil from 'Shape' contains more palmitic acid and linolenic acid and less oleic acid than the oils from 'CDC Bethune' and 'CDC Sorrel'. The stearic acid content of the oil of 'Shape' is higher than that of the reference varieties.

Description:

HYPOCOTYL: weak to moderate anthocyanin colouration

FLOWER: flattened disk shape, medium sized corolla, no longitudinal folding of the petals, absent to weak sepal dotting, medium blue petal colour, white filament, blue anthers, white style, pale violet stigma

CAPSULE: medium size, semi-dehiscent, no ciliation of the false septa
SEED: medium brown, medium size

DISEASE RESISTANCE: immune to flax rust (Melampsora lini), resistant to flax wilt (Fusarium oxysporum f. sp. lini)

AGRONOMY: good resistance to shattering, lodging and capsule loss

USE: oilseed flax variety

Origin & Breeding History: 'Shape' (experimental designation FP2188) was developed by Agriculture and Agri-Food Canada at the Morden Research Station, Morden, Manitoba. The original cross between 'M4684' and 'FP 1043' occured in 1997. The pedigree method was used to advance the line with selection criteria based on oil content, oil quality, lodging resistance and rust resistance. Single plant selections were made in the F3 and F5 generations. An F7 line, designated 'M7308', was selected and evaluated in preliminary yield trials in 2003 and for Fusarium Wilt trials in Manitoba and Saskatchewan. This line was further evaluated from 2003 to 2006 in Manitoba and Saskatchewan.

Tests & Trials: Tests and trials for 'Shape' were conducted during the summers of 2007 and 2008 in Morden, Manitoba. Plots consisted of 6 rows that were 5.5 meters in length with a row spacing of 18 centimeters.
