Successful winter canola (Brassica napus L.) production creates diversity and provides crop rotation alternatives for producers. Stand establishment and winter survival are among the main determinants of success in winter canola production. The objective of this research was to investigate the impact of environment, crop management, genetics and their interactions on canola stand establishment, survival, yield, and oil and protein content. Two datasets were analyzed: results from the National Winter Canola Variety Trials conducted from 2003 to 2012 and data from experiments conducted for 3 yr (2010–2012) in Manhattan, KS, to assess the impact of planting date, tillage, and cultivar on canola yield and survival. Canola has the potential to yield up to 7 Mg ha–1; however, actual yields were usually in the range of 0 to 4 Mg ha–1. The average oil content of canola seeds was 40%, but the potential extended to 47%. Environment, defined as a combination of year and location, was responsible for the majority of variation in yield, oil content, stand establishment, and survival of winter canola. Planting in mid to late August and early September benefited yield most of the time compared with planting late in September or October in the Great Plains and Midwestern United States. Only with extremely early or late planting did tillage improve winter survival and yield compared with no‐till. Crown height of canola was greater in no‐till treatments compared with conventional tillage treatments, but a significant relationship was not observed between crown height and winter survival or yield. Cultivars differed significantly in yield, survival, and crown height, but no cultivars were consistently superior in no‐till conditions or with plantings outside of the recommended time frame.

Surefire' (Reg. no. CV-27, PI 689513) is a winter canola (Brassica napus L.) cultivar that possesses tolerance to sulfonylurea herbicide carryover in the soil. Surefire will replace 'Sumner', which was the first winter canola cultivar released with this tolerance for the southern Great Plains. Sulfonylurea herbicides, or acetolactate synthase (ALS) inhibitor herbicides, have significant plant-back restrictions for susceptible crops, and they often limit rotating to canola in wheat (Triticum aestivum L.)-based cropping systems. Planting tolerant cultivars allows canola producers to avoid the plant-back restrictions. Surefire was released by K-State Research and Extension and was tested under the experimental name KSUR1211. Surefire drew attention in the 2012-2013 growing season as an entry in the sulfonylurea residual tolerance yield trial. It was the top-ranked cultivar at Hutchinson and Manhattan, KS, averaging 3452 and 4232 kg ha −1 , respectively. Across Great Plains sites of the 2015-2016 and 2016-2017 National Winter Canola Variety Trial, Surefire averaged 522 kg ha −1 more than Sumner. Surefire is about 4.2 d later to 50% bloom than Sumner. 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.

“…Additionally, an analysis was performed across site‐years in Kansas using only cultivars shared by all trials. Analyses across years had site‐year and cultivar as fixed effects and replication (site‐year) as a random effect (Stamm et al, 2012).…”

“…Variety was the whole plot randomly assigned within a replication, and forage harvest treatment was randomly assigned to subplots within whole plots. Whole plots included the cultivars Griffin, ‘Kiowa’ (Stamm, 2010), ‘Sitro’, and Wichita in 2008–2009; Griffin and Wichita in 2009–2010; and ‘Abilene’ (Rife et al, 2003), Griffin, Kiowa, Plainsman, ‘Riley’ (Stamm et al, 2012), Sumner, and Wichita in 2010–2011. The split‐plot forage harvest treatments were PRE (before a series of freezing temperatures less than −2.0°C), POST (following a series of freezing temperatures less than −2.0°C), SPRING (at bolting stage), and NONE (no harvest).…”

Griin' (Reg. No. CV-25, PI 672148), is a canola-quality, winter oilseed rape (Brassica napus L.) and is a dual-purpose forage and grain canola cultivar developed for Kansas, with potential to be grown across the southern Great Plains. It was tested as the experimental cultivar KS4022 and was released by K-State Research and Extension. The ability of Griin to withstand the efects of simulated grazing and its excellent forage quality compared with 'Wichita' make it a good candidate for dualpurpose use. In simulated grazing studies, Griin had winter survival superior to Wichita across all treatments; Griin averaged 80.4% survival across grazing treatments, whereas Wichita averaged 69.4%. At the optimum timing for forage harvest, Griin's inal grain yield was reduced by 36.6%, while Wichita's inal grain yield was reduced by 61.1% compared with the no-forage harvest treatment. Griin yields a highprotein, highly digestible, nutritious forage for livestock producers. Griin also possesses beneicial morphological features that could be used in breeding of new cultivars. A prostrate growth habit and the ability to avoid fall stem elongation are important characteristics to consider when selecting a canola cultivar with optimum winter survival.
