2014 Priorities High priority will be given to research that identifies and addresses the major impediments to the expansion of canola acreage and production. Specific research priorities considered for funding may include, but are not limited to (not listed in order of importance): 1. Production practices that optimize yield, quality, and profit 2. Disease management with emphasis on blackleg management. Note: sclerotinia research proposals should be submitted to the Sclerotinia Initiative. 3. Insect management, identification and control 4. Straight-harvest canola research, including the use of desiccants
2014 Priorities 5. Rotation studies that determine optimal broadleaf crops to precede canola
6. Reduction of pod shattering, including identification of varieties resistant to shattering 7. Increasing oil yield per acre in canola
8. Nitrogen/sulfur fertility management, including useefficiency studies 9. Other traditional or non-traditional research that has potential to increase canola acres and production 10. Evaluating and improving canola production on marginal lands (e.g., saline soils).

Canola Pathology – Summary Dr. Luis del Rio
Canola Pathology – Summary Current situation:
• Two most important diseases affecting canola production are blackleg and sclerotinia stem rot. • Blackleg is reemerging while sclerotinia has been held in check to due to weather, improved management, and fungicides. • A 2014 survey of 114 fields revealed blackleg presence in 80% of them; severe yield losses recorded in a few fields • Genetic resistance is the most effective way to manage these diseases
Canola Pathology – Summary What is the potential impact of this research? • 2013 state canola production worth US$ 314 million (USDA- Ag Statistics, 2014)
• Blackleg could reduce yield by >60%; Sclerotinia stem rot could reduce it by 30% • Managing Sclerotinia stem rot requires >300,000 pounds of pesticides per year • If materials produced by this project reduce losses due to both diseases by 5% each and fungicide applications for sclerotinia by 20%, direct savings would represent ~ US$32.4 million per year
Canola Pathology – Summary What have we accomplished so far? • Identified two advanced Brassica napus breeding lines and 21 plant introductions with resistance to blackleg • Breeding populations of a related species (B. juncea) were developed to identify markers associated with resistance to blackleg
Canola Pathology – Summary What is next? • Field trials to validate resistance of NDSU advanced breeding lines to blackleg • Identify markers and transfer blackleg resistance from B. juncea and B. napus plant introductions into advanced B. napus breeding lines • Evaluate other B. napus plant introductions for resistance to other strains of blackleg
NIFA-North Central Region Canola Research Project Project title: Development of high oil per acre conventional canola cultivar using classical and molecular approaches
Project report: Year 2014-2015
Dr. Mukhlesur Rahman NDSU Canola Breeding Program
Background Why canola breeding is required in ND? Alberta
Industry Breeding Saskatoon Manitoba
ďƒ˜ Canola variety grown in ND are developed and tested mostly in Saskatoon. As a result cultivated varieties may not be the best adaptive in ND conditions. ďƒ˜ Therefore, ND required a breeding program to develop and to evaluate canola variety in ND conditions.

Activities accomplished in 2014-2015
Classical breeding approaches • Parents used for crossing: 6 high seed yield, and 6 high oil content parents were used.
• Crossing: Partial Diellal crosses were made. • Place of activities: 25 Crosses, F1 and F2 were generated at NDSU greenhouse.

Genome sequence: 367 conventional canola accessions have been sequenced partially by GBS (Genome by sequence). Marker identification: This sequence information will be used to identify markers for seed oil content genes. Resource for other traits: The genome sequences could be used to identify markers for other agronomic traits.

Ensuring optimal pollination of canola crops for maximum yield in North Dakota Sean Griffin Rutgers University – New Brunswick, NJ
Questions 1. Does pollination increase canola yield? 2. If so, are canola crops in North Dakota receiving sufficient pollination from honey bees?
3. Does distance from apiaries matter? 4. What is the added value of honey bee pollination to canola yield and profitability?
Methods • Conducted all work in Cavalier County, ND in collaboration with the Langdon Research Extension Center • Examined two common canola varieties: DeKalb 70-07 and Invigor L252 • Conducted pollen limitation experiments at varying distances from honey bee apiaries, and at 2 positions within each field
Pollination experiment methods • 4 treatments: – Hand pollinated (maximum) – Bagged (minimum) – Control (open to honey bees) – Hand pollinated and bagged (to test effect of bag) • For each pollen limitation experiment, 10 plants for each of 4 treatments (40 plants total) • Seedpods collected 14 days after treatment
Results • Between June and September 2014, conducted pollination experiments at 12 DeKalb 70-07 fields and 8 Invigor L252 fields • Collected a total of 8,400 seed pods
• Currently still in the process of counting seedset of the pods collected from each treatment
Implications for canola growers • Insufficient pollination can cause a substantial loss of yield – Will evaluate loss of profit and conduct costbenefit analysis • Management options: – Place honey bee hives within fields rather than on edges – Moving hives throughout bloom period – Increasing hive density
