CFCRA Corn Project; Activity 1: Development of short season, cold tolerant, disease resistant corn inbreds
Principal
Investigator: Lana Reid
Research Institution: Ottawa
Research & Development Centre, Agriculture & Agri-Food Canada
Project Start: April 2018
Project End: March 2023
Funding Partners:
Funding
for the Corn Project is provided by the Agriculture and Agri-Food Canada
AgriScience Program through the Canadian Agricultural Partnership, with
industry support from the Canadian Field Crop Research Alliance (CFCRA) whose
members include: Atlantic Grains Council; Producteurs de grains du Quebec; Grain
Farmers of Ontario; Manitoba Corn Growers Association; Manitoba Pulse &
Soybean Growers; Saskatchewan Pulse Growers; Prairie Oat Growers Association;
SeCan; and FP Genetics. Additional
industry funding beyond the core CFCRA members is provided by organizations
representing the Canadian fertilizer industry.
Objectives:
- Development and release of early maturing cold tolerant corn inbreds with emphasis on the 1800-2000 CHU market.
- Development of corn inbreds with improved disease resistance to gibberella ear rot (GER), northern corn leaf blight (NCLB), Goss’s wilt, common rust, and eyespot.
Impacts:
- The expansion of corn acreage by the release of new genetics and technology for growing corn in early maturity regions of less than 2800 crop heat units (CHU)
- The improvement of corn yields and grain quality by reducing the incidence and severity of the major diseases, especially those contaminating the grain with mycotoxins
- Improve yield and quality of the grain, and knowledge, will help corn growers to select appropriate resistant hybrids
Activity
Summary:
This activity will use conventional corn breeding methodology enhanced by
double haploid inbred production and specialized screening techniques for cold
tolerance and disease resistance to develop early maturing cold tolerant corn
inbreds with improved disease resistance to Gibberella ear rot, northern corn
leaf blight (NCLB), Goss’s wilt, common rust and eyespot. Multiple yield trials
in Alberta, Manitoba, Quebec, Ontario and PEI will be conducted annually.
Disease nurseries for GER, NCLB, rust and eyespot will be conducted in Ottawa
and one new nursery will be established, in Manitoba for Goss’s wilt. Annual
surveys for current and emerging diseases will be conducted to continue to
guide the inbred development program on which diseases to put more resources
into and to scout for new/emerging diseases.
