Hard red spring wheat (Fig. 30) is grown principally in the north central part of the United States, where winters are too severe for the production of winter wheat. The states of Noi^th Dakota, Minnesota, and South Dakota lead in its production. Nearly I4 million acres of this class of v/heat are grown annually in the United States, comprising nearly one-fourth of the total vvfheat acreage. Al- though there are 24 distinct varieties of hai-d red spring wheat, about two-thirds of the acreage of this class "consists of the one variety. Marquis. The strongest flours for bread making are'produced from hard red spring .vheat. Durum wheat, i,Fig. 3I) in almost the same region as hard red spring wheat, ^e leading states in its production are North Dakota, South Dakota, and Minnesota. The region of heaviest production of durum wheat is just .vsst of the Red River Val- ley in North Dakota. About four million acres of durum wheat have been grovm annually in the United States for sever- al years. It comprises about one-sixteenth of the total wheat acreage. Arnautka and Kubanka are the leading varieties among the eleven commer- cial durum v/heats grovm. Durum v/heat usually yields more than hard red spring v/heat in this northern spring v/heat region, due to its. Please note that these images are extracted from scanned page images that may ha
