BULLETIN 618, U. S. DEPARTMENT OF AGRICULTURE. 



Of the common wheats, Kharkof, of the Crimean group, outyielded 

 even Pelissier in the 7-year period by 5 bushels, or 16 per cent. The 

 leading spring common wheats are outyielded by the durums in 

 quantities that are significant. Fife and Preston outyield Bluestem. 

 Marquis, however, which was not included in the experiments until 

 1913, has an average yield of 33.1 bushels during the four years, 

 compared with 28.8 bushels from Rysting Fife, 30.8 bushels from 

 Kubanka, and 32.3 bushels from Pelissier. In these four years, 

 therefore, it has outyielded not only the Fife wheat, but the two best 

 durums as well. The durums, especially Pelissier, unquestionably 

 are good wheats for this section. Marquis is as good and the hard 

 red winter wheats are better than either. 



Here, as at Akron, Colo., Pelissier has proved the best adapted of 

 all durum wheats tested. These experiments, together with those 

 at Archer, Wyo., and the result of a single year at Havre, Mont., 

 indicate that Pelissier is the best-yielding durum wheat yet obtained 

 for the drier western plains area having an altitude of 4,000 feet or 

 more. 



RESULTS AT BRANDON, MANITOBA. 



The Brandon Experiment Farm is located on a sandy loam soil. 

 Its altitude is 1,176 feet, and its average annual rainfall is 13 inches, 

 according to a 9-year record. The station is maintained by the 

 Canadian Department of Agriculture, and the data presented in 

 Table .XXV have been taken from the published annual reports 

 (Canada Experimental Farms, 1896-1908).

A variety of durum wheat was included in the experiments from 

 1895 to 1905. It was grown under the name Goose, but is probably 

 the Arnautka variety. Two other varieties were included in the last
