CEREAL EXPERIMENTS AT CHICO, CALIF. 
13 
this class have been grown in this region since the beginning of the 
industry. They were originally introduced from Australia, where 
the climate is very similar to that of portions of California. 
The soft white wheats are comparatively low in crude-protein 
content and high in starch. Their bread-making qualities, however, 
are fairly good. Repeated efforts have been made by growers and 
experimenters to introduce the superior high-grade hard red milling 
wheats from the central and northern United States, but without 
much success. The climatic conditions immediately result in in- 
ferior quality and usually in lower production than from the com- 
monly grown white varieties. 
In the varietal experiment the effort has been to discover wheats 
of better quality and higher yields for California. The varieties 
showing greatest promise in this direction are the hard white wheats 
of Australian origin. Where productiveness and general adapt- 
ability are approximately the same, quality as determined by milling 
and baking experiments has been the deciding factor in favor of a 
variety in the experiment. The interpretation of results is based on 
the varied data recorded and also on observations of varietal behavior 
and the effects of soil variation.
