Details for: PI 697260, Brassica napus L., 'KS4719'

KS4719 is a winter canola cultivar that possesses superior winter hardiness, greater lodging resistance, and improved pod shattering over previous Kansas State University releases. It is theorized that the improved lodging resistance of KS4719 comes from a stem and root system that are less prone to rotting in saturated soils. Greater winter hardiness is in part due to protection of the lower stem (rosette) throughout the winter months. KS4719’s seed oil (409 g/kg) and seed protein (226 g/kg) contents fall within the acceptable range of today’s commercial cultivars. Seed oil fatty acid profile was 4.0% (16:0), 1.8% (18:0), 69.7% (18:1), 18.7% (16:6), 5.5% (18:3), 1.1% (20:1), and 0.0% (22:1) and the total glucosinolate content of the defatted meal was 19.8 µmols/gram. KS4719 reaches 50% bloom 4 days later than Riley and 2 days later than Wichita. Maturity date is about 1.5 days later than Riley and 2 days later than Wichita. KS4719 is about 10 cm taller than Wichita. KS4719 would be considered intermediate in its resistance to blackleg (L. maculans).
