| 0 | PI 689513 | 'Surefire' | Brassica napus L. | Kansas, United States | PVPO | | Not Available | 2018 | DEVELOPED | | | | | | Cultivar | Surefire is a winter canola cultivar that possesses tolerance to sulfonylurea herbicide carryover in the soil. Surefire will replace Sumner, which was the first winter canola cultivar marketed in the southern Great Plains region with this tolerance. Sulfonylurea herbicides, or acetolactate synthase inhibitor herbicides (ALS), can have 18 to 24 month plant-back restrictions for susceptible crops, limiting rotation to canola in wheat-based cropping systems. Canela cultivars with tolerance to sulfonylurea herbicide carryover allow producers to plant winter canola in the fall following the spring application of a sulfonylurea herbicide. Surefire does not differ from Sumner in its tolerance to sulfonylurea herbicide carryover. The later maturity of Surefire gives it a distinct yield advantage over Sumner as fuller season cultivars typically yield more than early maturity cultivars. Surefire has a seed glucosinolate content of 14.6 µmol/g in the defatted meal. The average fatty acid profile of Surefire measures 4.4% (C16.0), 1.5% (C18:0), 65.8% (C18:1), 17.8% (C18:2), 6.8% (C18:3), 1.4% (C20:1), and 0.0% (C22:1). Surefire has a 3% greater C18:1 content compared to Sumner. Surefire shows good tolerance to blackleg fungus (Leptosphaeria maculans). | 1970843 | PI 689513 |
