Redchaff. — Redchaff has been an important variety in portions of 
the Columbia Basin of Oregon and Washington for nearly 20 years. 
It differs from Jenkin in being shorter and earlier, and in having 
more club-shaped heads and lighter brown glumes. Although a 
spring wheat, Redchaff most often is fall sown. About 40,000 acres 
of the variety were reported grown in 1919. Redchaff is a high 
yielding wheat along the foothills of the Blue Mountains in Oregon, 
but often is outyielcled by Hybrid 128 when sown in the fall. 
Six samples of the Redchaff variety have been milled and baked, 
all of which have come from commercial sources in the sections 
where it is grown. The data, presented in Table 60, show the variety 
to average low in crude protein, water absorption of flour, and loaf 
volume, and to be hardly equal to Jenkin or Hybrid 128 for mill- 
ing and bread making. 
SUMMARY OF MILLING AND BAKING DATA OX THE VARIETIES OF WHITE WHEAT. 
A summary of the milling and baking data on the varieties of 
white wheat is shown in percentages of Pacific Bluestem in Table 
73 and graphically in Figure 11. These are from the data presented 
in Tables 62 to 72, inclusive. 
Bobs, Federation, Galgalos, Hard Federation, and White Federa- 
tion have the highest loaf volumes, and Galgalos the highest protein 
content. Bobs, Talimka, White Federation, and Goldcoin have the 
highest flour yield. The data presented show that Bobs, Hard Fed- 
eration, White Federation, Federation, and Galgalos are among the 
best of the white wheats for bread making. Baart, Dicklow, and 
Pacific Bluestem are of good milling and baking quality, while 
Goldcoin and the club wheats, Hybrid 128 and Little Club, are very 
low in bread-making qualities. Talimka shows rather good milling 
and baking qualities, but is not promising as a commercial wheat.

stem, on comparable samples of 11 other varieties of white wheat grown 
during one or more of the seven years from 1915 to 1921, inclusive.
