Variety Description

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

Summary: '2126' has a shorter main axis of the stem at capsule maturity than the reference varieties. The flowering date of '2126' is earlier than the reference varieties. '2126' is lacking ciliation of the false septa of the capsule while in '2047' it is present. The seed of '2126' is slightly darker yellow than '1084' but slightly lighter yellow than '2047'. '2126' has fair resistance to lodging while in '1084' and '2090' it is good. The percent protein content of '2126' is higher than in '1084'.


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

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

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

AGRONOMY: fair resistance to lodging, medium capability to produce basal branching

USE: oilseed flax variety

Origin & Breeding History: '2126' was developed by United Grain Growers Ltd. by crossing 'SP992' to '94-7889' in 1995 in Morden, Manitoba. 'SP992' was derived from NorMan/Zero//CPI84495/3/NorMan3 and 94-7889 was derived from high oil strains 90-5889/AC McDuff. 90-5889 was derived from NorMan/Zero//CPI84495/3/NorMan2. 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 1999 (5 locations) and in 2000 (8 locations) as 95-25-F9-127-3. The line was evaluated as SP2126 in the 2001-2003 Low Linolenic Flax (Solin) Co-operative Test.

Tests & Trials: Trials were conducted in the summers of 2003 and 2004 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.
