CEREAL EXPERIMENTS IN MARYLAND AND VIlMilNIA. 47 



more than 1 ton. The average weight per bushel of the variety for 

 six years at Arlington Farm was 43.3 pounds. 



Numerous other varieties which have been included in the tests 

 are practically identical with the Tennessee Winter in appearance, 

 hardiness, and yield. Among these are the Maryland Winter, C. I. No. 

 518; Texas Winter, C. I. No. 554; Union Winter, C. I. No. 583; and 

 ( lanada Winter, C. I. No. 713. Two selections from the cross between 

 the Tennessee Winter and the Black Arabian, C. I. Nos. 895 and 896, 

 are also much like the Tennessee Winter. They have been among 

 the best yielders during the four years they have been grown. The 

 Tennessee Winter and similar varieties seem to be better adapted 

 for fall seeding in the locality of Washington, D. C, than any of the 

 other winter barleys. 



Wisconsin Winter. — The Wisconsin Winter barley, C. I. No. 519, 

 appears to be a winter variety from a region of mild winters. It is 

 winter hardy in the vicinity of Washington, but the plants make a 

 more vigorous top growth in the fall than those of the Tennessee 

 Winter and similar varieties, while the leaves are much wider and the 

 winter habit is less pronounced. The yield of the Wisconsin Winter 

 at Arlington Farm during the six years from 1909 to 1914 was 27.52 

 bushels, which is 0.45 bushel less than that of the Tennessee Winter 

 for the same period. The average date of maturity for the variety is 

 three days later than that of the Tennessee Winter. 



Arlington. — The Arlington (Arlington Awnless) barley, C. I. No. 702, 

 is a 6-rowed awnless hulled barley which was developed by selection 

 from a hybrid between the Tennessee Winter and the Black Arabian, 

 the latter being a 2-rowed bearded hulled variety. This selection 

 was continued through several years by Mr. H. B. Derr, formerly of the 

 Office of Cereal Investigations. 1 It is the earliest variety included in 

 the tests, ripening about May 26. Because of its awnless character 

 and its earliness it was expected that the Arlington would become a 

 very important winter variety, as it appeared to be nearly as hardy as 

 the Tennessee Winter. The data on yield contained in Table XII, 

 however, show that the Arlington is much inferior to the Tennessee 

 Winter and similar varieties. In the three years from 1912 to 1914 

 at Arlington Farm the Arlington averaged 20.11 and the Tennessee 

 Winter 29.24 bushels. The heads of the Arlington are very brittle, so 

 that a considerable part of the grain is lost by shattering in harvesting 

 and subsequent handling before thrashing. For these reasons it is 

 doubtful whether the Arlington will become of much importance. 



Virginia. — The name Virginia (Virginia Hooded), C. I. No. 648, 

 was applied by Mr. H. B. Derr to a hooded selection from a hybrid 

 between the Tennessee Winter and the Success, a 6-rowed hooded 

 hulled spring barley. It was hoped that this variety would prove to
