be winter hardy and that it would be a valuable addition to the list 

 of winter barleys, as its freedom from beards makes it much more 

 pleasant to handle than the ordinary winter varieties. It entirely 

 winterkilled, however, in January, 1912, and was rather badly injured 

 in one or two other years. Its average yield for the five years from 

 1910 to 1914 at Arlington Farm is 21.4 bushels, which is about 3 

 bushels less than that of the Tennessee Winter, Texas Winter, and 

 similar varieties for the same period. This variety matures about 

 four days earlier than the Tennessee Winter. The yield of straw is 

 rather less than from the bearded winter varieties. The grain has 

 been light and chaffy, averaging only 38.8 pounds to the bushel, as 

 compared with 43.3 pounds for the Tennessee Winter. 



THE 2-EOWED HULLED GROUP. 



Most varieties of the 2-rowed group which have been grown at 

 Arlington Farm were originally spring barleys which have been sown 

 in the fall. They have not proved to be winter hardy in years when 

 low temperatures are recorded, though in favorable years they have 

 produced very high yields. They are not sufficiently dependable to 

 make them worthy of recommendation. 



Two selections from a hybrid between the Tennessee Winter and 

 the Black Arabian, however, appear to be quite hardy and worthy of 

 further test. These are the Nesbian, C. I. No. 647, and the Omar, 

 C. I. No. 898. It is probable that the latter is the better of the two 

 selections, though it has not been tested long enough to determine its 

 value fully. These hybrids mature a day or two later than the 

 Tennessee Winter. In the tests so far conducted they have not been 

 high in yield. The average yield of the Omar for the two years in 

 which it has been tested is 25.3 bushels, as compared with 26.2 

 bushels for the Tennessee Winter and 32.45 bushels for the Wiscon- 

 sin Winter in the same years. The quality of the grain produced by 

 these 2-rowed varieties is much better than that of the 6-rowed 

 barleys, the average weight per bushel being practically 48 pounds. 



THE NAKED GROUP. 



None of the varieties in the naked group have produced yields 

 nearly as high as those of the 6-rowed hulled varieties. The best 

 naked barley which has been included in the test is a selection from 

 a hybrid which has been called Hansee, C. I. No. 703. This selection 

 was made by Mr. H. B. Derr from a cross between the Tennessee 

 Winter and the Hankau, C. I. No. 197, the latter a 6-rowed bearded 

 naked variety. The Hansee is also a 6-rowed bearded barley. While 

 it is apparently not a true winter variety, it is much more hardy than 

 any of the other naked barleys which have been tested. Its average 

 yield for the four years it has been grown at Arlington Farm is 20.8
