b'Manitoba Agriculture Variety GuideCANOLA OAll variety yields compared as a percentage of the check specific to that trial. Check variety was chosen based on % of acres grown in MASCI2023 Variety Marketshare Report.Liberty Link trial was run as separate from Roundup-Ready. All canola yield trials are straight-cut. LYields derived over two or more growing seasons are the best indicator of variety performance. Use single site year data with caution. SComments:Variety descriptions summarize the performance of varieties tested in the 2024 Canola Variety Evaluation Trials. Data donated by the ManitobaECanola Growers Association. For more information visit www.canolagrowers.com.Lodging is rated on a 1 to 5 scale, where 5 is a completely lodged plant at harvest. EBlackleg Resistance DVarieties in the table below have a resistant (R) rating for Blackleg (30% infection of Westar check) based on WCC/RRC rating. Lesions and yield loss can still occur, based on the level of inoculum and blackleg pathotype in the field, in combination with environmental conditions conducive for disease development. Some seed distributors have chosen to provide blackleg 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, and X. Adult-plant (quantitative) resistance remains an important factor. Visit www.blackleg.ca for details on howCresistance groups work.RClubroot ResistanceClubroot is a long-lived soil-borne disease that can impact canola performance. Using clubroot resistant varietes in Rural Municipalities whereOclubroot has been found is highly recommended as a risk mitigation tool. To know for sure if your own fields have clubroot, soil testing is the only way to find out prior to finding galls in the field. See page 59 for the map indicating clubroot distribution in Manitoba. PClubroot resistance is generally termed 1st or 2nd Generation based on genetic source. First-generation clubroot resistance confers resistance to clubroot pathotypes 2F 3H, 5I, 6M, and 8N, on the Canadian Clubroot Differential Set (Strelkov et al., 2018). Second-generation sources contain resistance to a varying set of pathotypes outside the original five first-generation pathotypes, but may also have resistance to the originalSfive.For further information on clubroot resistance labels, please visit www.clubroot.ca, refer to the company website, or speak with your seed representative.Pod Shatter ResistanceThe pod shatter rating scale was developed by the Canola Council of Canada in 2021.Numeric pod shatter ratings are provided by their respective companies, or may not yet be identified on the new rating system.LIBERTY LINK CANOLAVariety DescriptionManitoba CVET Data1WCC/RRC Data2 Pod YieldBlacklegClubrootShatterHerbicide# of% ofYieldMaturityLodgingResistance4aResistance4bRating5NameTolerance3SitesCheck(bu/ac)(Days)(1-5)(Group)(Generation)(1-9)Liberty Link - Straight CutB3012LL488%5095.11.3RR (1)Y (7.0)BY 7204LLLL490%5292.91.3R (E2)R (1+2)Y (7.5)CP21L3CLL484%4892.91.5RR (1)N (5.4)CP24L3CLL489%5193.41.3RR (1+2)Y (7.0)CS4000 LL LL484%4891.92.3RR (1)Y (6.0)InVigor L340PCLL4100%5790.61.7RR (1)YInVigor L343PCLL494%5490.71.9RR (1+2)YInVigor L350PCLL493%5395.11.3RR (1)YInVigor L356PC LL496%5591.91.5RR (1)YLSD 63.61 Data from independent canola hybrid testing in the Manitoba Canola Variety Evaluation Trials.2 Data from canola hybrid registration testing at Western Canadian Canola/Rapeseed Recommending Committee Trials.3 Herbicide tolerance is indicated as LL - LibertyLink, TF - TruFlex, RR - Roundup Ready, CL - Clearfield4 Genetic disease resistance is indicated with an R resistant rating to Blackleg, Clubroot, based on variety descriptions submitted to CFIA. 4a,4b Additional details of blackleg group and clubroot generation labels provided by respective companies.5 The Canola Council of Canada rating system indicates that 1 = poor, SEEDMB.CASEED MANITOBA 2025 51'
