Flax is primarily a southern crop!
Flax is not well adapted to the North
Is not selected for tolerance to cold soils or spring frosts
Historically is a later sown cropSome varieties can start reflowering under cool, wet
autumn conditions (indeterminate)Some varieties have stems that seem to stay green
long after the bolls are ripeFlax is late maturing in the northFlax has late and sometimes challenging harvests
Martin Moore, BC Grain Producer
“Some 15 years ago, Argentine canola was seen as a crop out of reach for most northern prairie regions as it was too long seasoned a crop. It was a risky crop in the north. Now Argentine canola is high yielding and matures on the tails of Polish canola.”
“Flax is where canola was 15 years ago and even with half the effort Argentine canola received, the same explosion of progress can be expected in flax.”
Northern Prairies
Flax requires more growing degree days to mature• Barley….1269……………...79% of flax• Canola…1432 …………..…89% of flax• Oats……1483………….…...93% of flax• Wheat…1538……….………96% of flax• Flax……1603……………..100% of flax
Miller, Lanier & Brandt, 2001 “Using Growing Degree Days to Predict Plant Stages”.
The Challenge
Northern Prairies
The northern prairies have less growing degree daysPeace River…….……1702 GDD (106%)Vegreville…………….1793 GDD (112%)Melfort………………..1856 GDD (116%) Saskatoon……………1932 GDD (121%)Morden…………….….2174 GDD (136%)
1603 growing degree days (GDD) required for flax
17-18% of the GDD from May 1st – May 31st 2007 data from Environment Canada
The Challenge
Northern Prairies
Flax has a challenging life cycle
45-60 day vegetative period 15-25 day flowering period30-40 day maturation period
Total requirement; 90-125 days
Canola has a shorter vegetative period and a longer flowering period (Brandt).
The Challenge
Northern Prairie
Higher yields-less impact from drought
Better oil quality-cooler temperatures
Opportunities

Northern Adapted Flax Project
1. For the first time in history, a major flax breeding program is located in the northern prairies (Vegreville).
2. Vegreville climate is cooler, shorter frost free period, longer days (photoperiod response)
3. The Viterra flax program is in the ‘zone’ and should be successful in developing flax varieties for the north
4. With support, Viterra will focus up to 50% of its flax R&D program to this project.

Northern Flax ProjectBreeding Strategies
1. Improve cool soil germination /seedling frost tolerance
(need to extend growing season by earlier seeding)
Our 2009 nursery at Vegreville was sown from May 6th to May 15th. Soil was cool (~5oC) and conditions got colder
May 10th -2.5 May 20th -0.7 June 2nd -1.5
May 12th -2.5 May 21st -2.5 June 6th -3.1
May 13th -3.4 May 22nd -5.8 June 8th -2.0
May 14th -1.9 May 23nd -0.9 June 9th -1.8
May 18th -2.3 May 29th -0.4
Northern Flax ProjectBreeding Strategies
2. Select daylength sensitive lines to trigger early maturity
8-17 days earlier than CDC Bethune
Northern Flax ProjectBreeding Strategies
3. Identify determinate lines (will not start reflowering in response to autumn rains).
Northern Flax ProjectBreeding Strategies
4. Identify lines with stems that turn brown when bolls mature
Northern Flax ProjectBreeding Work
• New flax lines will be developed by Viterra based on elite germplasm and PGRC early maturing accessions
• Flax lines with northern characteristics will be selected at the Vegreville nursery and then field evaluated at Melfort AAFC, Fort St. John, BC and Vegreville, AB.
• Breeding deliverables…in the first 5 years, up to 50,000 nursery rows, up to 5000 F5 full plots, up to 600 F6 lines in preliminary yield trials and up to 200 F7 lines in advanced yield trials will be generated and evaluated.
Northern Flax ProjectAgronomy Work
Agronomy is also required to identify best management practices for growing flax in the northern prairies
Dr. Jan Slaski (ARC) and Cecil Vera (Melfort AAFC)
Need to revisit impact of agronomy in the north
-variety, tillage, seeding date, seeding rate, seeding depth, seed treatment, fertilizer, weed management
Northern Flax ProjectConclusions
• This project will take 10 years to complete. Breeding for northern adaptation is a process and not an event. It will take many cycles of evaluation, hybridization, selection, evaluation, hybridization, selection, etc to be successful.
• The plan is to fix four northern traits; improved cold soil/seedling frost tolerance, determinate boll maturity, synchronous stem ripening, and a suite of maturity options in high yielding varieties.
• The plan is to also develop a set of best management practices to accompany these new varieties.
