Key Result

A collection of B. napus lines with adult plant resistance against blackleg disease was identified.

Project Summary

The objectives of this study are to:

  1. identify tightly-associated genetic markers for controlling adult plant resistance to blackleg.
  2. define the underlying genetic architecture of this durable resistance to blackleg in B. napus.

Overview:

A collection of 58 spring-type B. napus with adult plant resistance (also referred to as quantitative resistance, a durable form of resistance) against blackleg disease was identified. These lines offer a source of resistance against blackleg for potential incorporation into commercial canola cultivars.

Note: This study was one of many making up the ‘Canola Disease Management Tools for the Prairies – Blackleg and Sclerotinia’ project that was led by SaskCanola in partnership with industry and funded under the Agri-Science Project (ASP) within the Growing Forward 2 Program.
