Development of field-ready cultivars of winter wheat germplasm adapted to western Canada

Current research and/or projects

Mandate: The development of winter wheat cultivars for the various agri-climatic regions of western Canada that combine high yield and cold tolerance with superior productivity traits, enhanced disease and pest resistance, and end-use quality profiles that serve traditional and emerging markets.

Research and/or project statements

Principal Investigator

  1. Enhancing the stability of recent yield advances in western Canadian winter wheat. Western Winter Wheat Initiative, 2016-2020.  To breed improved disease and pest resistance into new higher yielding CWRW wheat cultivars to enhance the long term durability of the yield gains that have been recently been achieved.
  2. Development of improved wnter wheat cultivars for western Canada. Canadian National Wheat Cluster, 2018-2023.  To develop improved field-ready cultivars of winter wheat for western Canada.
  3. Premium quality hard red winter wheat for western Canada. Agriculture Funding Consortium, 2019-2022.  To develop over the medium term, winter wheat cultivars with CWRS-like end-use quality with yield, agronomics, and disease resistance competitive with current cultivars at the time of registration.
