DISTRIBUTION OF WHEAT IN THE UNITED STATES 
37 
The Kahla or black-chaffed durum is known by several names, 
principally Black Durum and Algerian. Its distribution in 1924 was 
rather scattered, as is shown in Figure 21. Its estimated acreage 
increased from 19,500 in 1919 
to 45,579 in 1924. The in- 
crease in acreage of this vari- 
ety is due to its good quality 
for the manufacture of semo- 
lina, from which high-quality 
macaroni and other edible 
pastes are made. It is not a 
high-yielding variety, nor is 
it resistant to stem rust.

Esti- 
The acreage of all other 
commercial durum varieties 
reported in 1924 increased slightly from 1919 to 1924, together with the 
increase in the total durum acreage. Mindum increased largely in 
Minnesota, in which State it was developed and to which it is well 
adapted. The increase of Peliss in Montana and of Marouani in 
Texas is not marked or of much importance. The new Nodak variety 
was first reported as grown in 1924. No acreage is estimated. It is 
a rust-resistant selection of Kubanka and of good quality for maca- 
roni making. 
Buford, Golden Ball, Kubanka No. 8, and Velvet Don, all regis- 
tered varieties, were not reported as grown in 1924. Akrona, a new 
variety of durum, also was not reported. Of the 15 recognized durum 
varieties, 10 were commercially grown in 1924. The returned sched- 
ules for 1924 indicated that durum varieties were becoming better 
known even though the varietal name for nearly three-fourths of 
the acreage of the class was not known. 
HARD RED WINTER WHEAT 
The hard red winter wheats (class 3) are grown chiefly in the central 
and southern sections of the Great Plains area of the United States. 
In 1919 the acreage of hard red winter wheat, as shown in Table 3, 
was estimated to be 23,328,247 acres, making up 32 per cent of the 
total wheat acreage of the United States. In 1924 the estimated 
acreage was 21,052,848 acres, which comprised 41.4 per cent of the 
acreage of ail wheat. The relative acreage of hard red winter wheat 
increased 9.4 per cent between 1919 and 1924. This was the most 
important class in both 1919 and 1924. 
The distribution of the acreage of hard red winter wheat in 1919 
and in 1924 is shown in Figures 22 and 23. 
The 1919 survey reported 8 varieties of hard red winter wheat 
which were being grown commercially, whereas in 1924 the reports 
showed a total of 17 varieties. All of the varieties reported in 1919 
were still being grown in 1924. The following varieties were first 
reported in 1924: Beloglina, Ilred, Iobred, Karmont, Michikof, Min- 
turki, Nebraska No. 6, Nebraska No. 60, and Ridit. The estimated 
acreage and percentage of the total wheat acreage occupied by the 17 
commercial varieties in 1924 are shown in Table 6.
