TESTS OF BARLEY VARIETIES IK" AMERICA 137 
DAVIS, CALIF. 
Davis, Calif., is situated in the Sacramento Valley in a section of heavy barley 
production. The Sacramento and San Joaquin Valleys are the most important 
centers of production of barleys of the Coast type in the United States. Barley 
was brouglit into California with the early missions. Its production extended 
rapidlv in the Sacramento and San Joaquin Vallevs after the discovery of gold 
in 1848. 
The University Farm at Davis has been an important station in the testing and 
production of varieties and is very favorably situated for the continuation of 
experiments in barley. Yields from 1908 to 1920 have been furnished by the 
California Agricultural Experiment Station. These are reported in Taljfe 79. 
Three or four varieties which could not be definitely identified were not included 
in this table. Ten varieties are compared in detail in the summarized digest of 
Table 79. Of these, the two highest yielding were Coast (C. I. Nos. 2821 and 
626). Coast (C. I. No. 2821) is a selection developed by the Cahfornia Agricul- 
tural Experiment Station and distributed as California No. 4000. The name 
"Coast" is given here not with the intention of changing the varietal name as 
far as its use in California is concerned, but simply to identify its type more 
definitely in this bulletin. Coast (C. I. No. 626) is the ordinary commercial 
barley of California. California Mariout (C. I. No. 1455), which was third in 
point of yield, is a variety which has been distributed by the California station. 
The history of this and of California No. 4000 as well as the adaptation of 
these varieties is considered elsewhere in this bulletin. Of the 10 varieties com- 
pared, Beldi Giant (C. I. No. 2777) was fourth. All four of these varieties 
originated in North Africa. 
Fifth in point of yield was White Smyrna (C. I. No. 195). This variety origi- 
nated in Asia Minor under conditions somewhat similar to those found in North 
Africa. Hannchen was the highest yielding sort of any of those which do not 
trace back to either North Africa or Asia Minor. Hannchen (C. I. No. 531) pro- 
duces very good results in California, but is obviously not so well adapted as the 
barleys of the North African group. Perhaps the most interesting variet}^ from 
the standpoint of 3'ield is Oderbrucker (C. I. No. 537). This barley was not 
grown many years, as it was obviously inferior. Although it is extremely well 
adapted to the northern Mississippi Valley, it is almost worthless in California. 
It was superior to none of the nine varieties with which it was compared, being 
inferior even to Nepal (C. I. No. 595), which is usually the poorest type grown. 
There is no question as to types of barleys best suited to the district around Davis. 
Barleys of North African origin are outstanding in their yielding capacity. 
Recently two barleys have been distributed in California which have quickly 
attained a commercial status. These are Club Mariout (G. I. No. 261) and 
California Mariout (C. I. No. 1455). Both came originally from Egypt. The 
acreage of the former is increasing rapidly in the Sacramento and upper San 
Joaquin Valleys, where it is meeting with a ready market in the export trade. 
California Mariout has been found to be superior under low rainfall conditions in 
the San Joaquin Valley, although its acreage is not limited to this locality.
