CEEEAL EXPERIMENTS AT JUDITH BASIN SUBSTATION. 37 
North Dakota Resistant No. 52, a wilt-resistant flax of the seed 
type, has not yielded as well as the Russian. 
The Smyrna flax (C. I. No. 30), which ranks second in average 
yield for the two years it has been grown, was imported from Smyrna, 
Turkey, by the United States Department of Agriculture, hi 1913. 
This variety has shorter straw and more numerous basal branches 
than the European seed flaxes. From results obtained elsewhere it 
seems to be better able to withstand unfavorable hot, dry weather 
than other varieties in the test. 
North Dakota Resistant No. 114 and Primost (Minn. No. 25), both 
of which belong to the short-fiber group, did not produce yields which 
compare favorably with those of the European seed flaxes. These 
varieties would probably give better results in regions where flax 
canker is more serious than at Moccasin. 
The textile fiber type of flax is of no value for seed production in 
Montana.

Fig. 16.— Diagram showing the average yields (in bushels per acre) of 
the leading varieties of flax at the Judith Basin substation for the five 
years, 1911 to 1915, inclusive. 
Table XXIV gives the average dates of seeding, heading, and 
ripening, the yields of straw and grain, and the weight per bushel of 
the five leading varieties of flax in the five years 1911 to 1915, inclusive. 
The average yields of these varieties are shown graphically in 
figure 16.
