Twenty-six samples of Hybrid 128 have been milled and baked, the 
average results of which are presented in Table 60. Several of these 
samples are from commercial sources. Seventeen of them, however, 
came from experiment stations and can be compared with an equal 
number of Pacific Bluestem samples grown in the same year. The 
samples are comparable except that Pacific Bluestem was grown 
from spring sowing in some cases, while all samples of Hybrid 128 
were grown from fall sowing. The samples are thought, however, 
to be sufficiently comparable to warrant a comparison and the re- 
sults are shown in Table 71. The data show Hybrid 128 to be 
high in yield of flour, low in crude protein content of wheat and 
water absorption of flour, and to be low in texture and color of 
loaf and exceptionally low in loaf volume. It is one of the poorest 
of the white club wheats in milling and baking values. Much of 
this wheat grown in the Pacific coast area is exported, and there- 
fore it is not much used for milling and bread-making purposes in 
this country.

Hybrid 143. — Hybrid 143 was originated at the Washington Agri- 
cultural Experiment Station from a cross between Little Club and 
White Track, the latter a common white winter wheat. This hy- 
brid wheat was first distributed by the Washington station in 1907 
and has since become rather widely grown in Washington. It is 
estimated that about 50,*000 acres of the variety were grown in 1919. 
Hybrid 143 usually is grown from fall sowing, but if sown early 
can be successfully grown from spring seeding. The heads and ker- 
nels are very small and short, and the kernels are considerably 
harder than those of Hybrid 128. Hybrid 143 usually is outyielded 
by Hybrid 128 when fall sown and by several common and other 
club varieties when sown in the spring. 
Eleven samples of Hybrid 143 have been milled and baked. Most 
of these samples are from commercial sources and therefore can 
not be compared with Pacific Bluestem. The data presented in 
Table 60 show Hybrid 143 to have a heavy test weight per bushel, 
but to average low in crude protein content, flour yield, and water 
absorption. It has, however, averaged higher than most of the va- 
rieties of White Club wheat in volume, texture, and color of loaf. 
Jenkin. — Jenkin has been grown in eastern Washington at least 
since 1895, but its origin is not known. It is a tall, late variety of
