Defiance wheat is variable in many of the 
characters above described, indicating that 
there are several different strains within the 
variety. Spikes and kernels of this wheat 
are shown in Plate X, B. 
History. — Defiance is the result of a cross 
of White Hamburg as the male parent and 
Golden Drop as the female parent, vviiich 
was made by Cyrus G. Pringle, in the Cham- 
plain Valley, near Charlotte, Vt., in 1871. 
It was first distributed in 1878 by B. C. 
Bliss & Sons, as Pringle's Defiance. It 
showed three distinct types of grain. Prof. 
A. E. Blount took some of this wheat to the 
Colorado Agricultural Experiment Station, where he grew it during a number 
of years and made careful selections. Three commercial varieties were devel- 
oped from it. viz, Early Defiance, Colorado No. 50, and Regenerated Defiance. 
Prof. A. H. Danielson, who succeeded Professor Blount at the Colorado station, 
has recorded the following interesting history of the origin of Defiance wheat : 
Before closing I want to give a little resume of the history of Colorado's most 
famous wheat. The mother of Defiance traces back to southern England and 
was originated by F. F. Hallett, of Brighton, in the sixties. He is the man 
who first used the word pedigree as applied to wheat. The mother was a de- 
cided club-shaped type with pretty red grain, somewhat soft, and Hallett called 
it the Golden Drop. It was quite popular in England, but never amounted to 
much either in this country or Australia. From England it went to Canada, 
where a man named Pringle got it as the Canada Club. The father of Defiance 
was a Dutchman from Germany, and rather soft at that, but white. It came 
from Hamburg, from whence lots of wheat emigrated in those days. It had a 
long, coarse broad head, a big white berry, and a rank-growing constitution with 
good ability to stand on its feet. Good old White Hamburg has long since been 
dead and buried to cultivation, at least under that name, but was largely 
grown on the Pacific slope during the early days of cereal culture there (76'). 
Distribution. — Grown from spring sowing mostly on irrigated land in Colo- 
rado. Idaho, Nebraska, Nevada, New Mexico, Utah, and Wyoming, and from 
fall sowing in western Oregon and southern Arizona and California. The dis- 
tribution of Defiance and Regenerated Defiance wheat is shown in Figure 20. 
Synonym. — Pringle's Defiance. As indicated above, this was the name under 
which the variety was first distributed by a seed company. In recent years the 
name Defiance has been generally used.
