The South Dakota Agricultural Experiment Station is releasing two new white oat varieties named SD Momentum and SD Titan to Certified Seed growers in the spring of 2024.
SD Momentum (Hayden/MN11140) was tested as SD170935 and a potential replacement for Goliath and Rushmore. It is similar to Goliath in maturity, height, test weight and forage dry matter yield with lower forage quality. SD Momentum is higher in yield with better straw strength. It is resistant to crown rust and smut along with moderate resistance to barley yellow dwarf virus. Grain characteristics are acceptable for milling with a similar Beta-glucan level as Goliath.
SD Titan (MN11140/SD120638) was tested as SD181245 and a potential replacement for Goliath. It is one day earlier than Goliath in maturity, one inch shorter in height and a lower than average test weight. SD Titan is higher in yield and forage dry matter yield, but slightly less relative feed value than Goliath, but higher than SD Momentum. It is moderately resistant to crown rust, smut and barley yellow dwarf virus. Grain characteristics are not acceptable for milling, but is an excellent choice for oat forage.
There will be a $0.30/bushel research fee on the sales of Certified SD Momentum and SD Titan Oats and Plant Variety Protection will be applied for. There will be no saleable Registered Seed class.
