A key finding of the survey showed that 94% of growers Blackleg Resistance Dand agronomists indicated that independent variety data isinfluential intheir canola purchasingdecisions. All varieties in the table below have a resistant (R) rating for Blackleg (30% infection of Westar check). Lesions and yield loss can still occur, In the past, a prairie-wide canola variety testing program Respondents indicated that independent testing is highly based on the level of inoculum and blackleg pathotype in the field, in combination with environmental conditions conducive for disease (Canola Performance Trials) was run collaboratively by the development. Some seed distributors have chosen to provide backleg resistance grouping based on major-gene (qualitative) resistance within that variety in addition to the traditional rating. Labels identifying major resistance genes present will use the letters: A, B, C, D, E1, E2, F, G, H, C ManitobaCanola Growers Association(MCGA), Alberta valued due to the unbiased, cross-company nature of third- and X.
