South Dakota is a major wheat producing state with a reputation for high quality, high protein spring wheat. Flour milled from hard red spring (HRS) wheat is used in breads, rolls, and cereal foods. Durum spring wheat is milled into semolina flour for macaroni, spaghetti, and other pasta. A bushel of wheat yields about 73 one-lb loaves of bread. A bushel of durum makes about 36 lb of pasta.
