Summary 24 
Several varieties of Australian wheat are important commercially 
in the Pacific coast area of the United States. Many others have 
been or are now under experiment at the agricultural experiment 
stations in this area. This bulletin gives the history of the introduc- 
tion of Australian varieties into the United States, describes them 
briefly, and presents the results of experiments with them at the 
Sherman County Branch Station at Moro, in the Columbia Basin of 
Oregon, and at the Plant Introduction Station at Chico, in the 
Sacramento Valley of California. Results of nursery experiments 
with 130 lots of Australian wheat recently introduced by the United 
States Department of Agriculture are presented also. Of these the 
Federation group, consisting of three varieties, Federation, Hard 
Federation, and White Federation, appears best adapted. The 
history and descriptions of these varieties are given, and also the experi- 
mental results thus far obtained with them in comparison with com- 
mercial varieties. 
Nearly all Australian varieties are white spring wheats. This type 
in the United States is grown only in the Pacific coast and Inter-
