Development of Field Pea Varieties with Improved Disease Resistance and Harvestability

Field pea variety development is a continuous process. It takes more than 10 generations to develop a variety. Each generation is built upon the materials developed in the previous generation. Several varieties have been developed in the GF1-PSC project. These varieties are currently at the stage of variety releasing and pedigree seed production. In addition, a large quantity of breeding materials have been developed, which include materials in the early generations (F2 to F6), breeding lines in F7 to F9.

The objectives of the project include the following components:

  1. Evaluate advanced breeding lines in Western Canada Field Pea Cooperative Registration Tests (Pea CO-OP Tests) for variety registration and produce breeder seed of new varieties.
  2. Develop and evaluate elite breeding lines at multi-geoclimatic regions to identify adapted genotypes. Field pea production areas in Western Canada include vast geoclimatic regions. The only way to identify adaptability of breeding lines to these regions is to evaluate their performance and select the most adapted ones in each and every region.
  3. Develop breeding materials with improved disease resistance and harvestability. Ascochyta complex, powdery mildew, and root diseases are most common and damaging diseases in Canadian field pea production. The level of the diseases, particularly Ascochyta, is associated with standabilty of a variety, the lesser the level of the diseases the better the standability.
