CEREAL EXPERIMENTS AT JUDITH BASIIST SUBSTATION.

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, 

 IHirkey, by the United States Department of Agriculture, in 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.

 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 grapliically in 

 figure 16.
