Variety Description

Varieties used for comparison: '1084', '2047', '2090' and '2126'

Summary: '2149' has taller plant height and length of the main axis of the stem at capsule maturity than '2047', '2090' and '2126'. The flower of '2149' has stronger sepal dotting than the reference varieties. '2149' and '2047' have a presence of ciliation of the false septa of the capsule while '1084', '2090' and '2126' do not. The seed of '2149' is a lighter yellow colour than '2047'. '2149' has a higher percent protein content than '1084', '2090' and '2126'. The oleic fatty acid content as, % of the oil, of '2149' is lower than in '1084', '2090' and '2126'.

Description:

FLOWER: flattened disc shape, medium corolla size, medium sepal dotting, no longitudinal folding of petal, light to medium violet petal colour, filament with blue top and white base, blue anthers, white pollen, style with blue top and base, medium violet coloured stigma

CAPSULE: medium size, medium maturity, indehiscent, presence of ciliation of the false septa
SEED: medium size, light yellow colour

DISEASE RESISTANCE: moderate resistance to Flax wilt (Fusarium oxysporum f. sp. lini)

AGRONOMY: good resistance to shattering and capsule loss, fair to good resistance to lodging, weak capability to produce basal branching

USE: oilseed flax variety

Origin & Breeding History: '2149' was developed by United Grain Growers Ltd. by crossing '1084' to '96-32-F3' in 1997 in Morden, Manitoba. '1084' was derived from SP946/Flanders and SP946 was derived from McGregor/Zero//CPI84495/3/McGregor2. 96-32-F3 was derived from 989/95-1002. 95-1002 was a high oil strain from Ed Kenaschuk. F2 and subsequent generations were advanced using the pedigree breeding method with selection criteria being seed colour, oil content, fatty acid profile, lodging resistance, disease resistance and agronomics. Single plant selection was made in the F3 and F5 generation. This line was evaluated in replicated field trials in 2000 and in 2001 as 97-1014-F6-128-2. The line was evaluated as SP2149 in the 2002-2004 Low Linolenic Flax (Solin) Co-operative Test.

Tests & Trials: Trials were conducted in the summers of 2003 and 2005 in Rosebank, Manitoba. There were four replicates arranged in a RCB design. Each plot consisted of an area of 3 metres x 1.2 metres.
