The varieties Spade, C. I. No. 1935, and Eclipse, Maryland No. 105, 

 are also among the best at College Park. 



The Missouri Bmestem when first grown at Arlington was a mixture 

 of a white-chaffed and a red-chaffed wheat. Selections were made, 

 and in 1913 the best strain, a red-chaffed one, was substituted for the 

 mixed stock in the tests. The white-chaffed strain was inferior and 

 was discarded. The Missouri Bluestem variety, C. I. No. 1910, 

 tested at College Park from 1908 to 1910, was identical with the 

 white-chaffed strain just mentioned. 



Awned, glumes pubescent, white. — Only five varieties included under 

 this group have been tested, of which two were grown at Arlington 

 and three at College Park. The Virginia, C. I. No. 3277, a hybrid 

 variety, is of sufficient promise to warrant special mention. While 

 it has not ranked unusually high in yield, the quality of grain in this 

 variety is superior to that of the other four varieties. 



Awnless, glumes glabrous, white. — The Fultz, C. I. No. 1923 and 

 Maryland No. 84, one of the oldest and best known varieties of soft 

 whiter wheat, probably is the most valuable of the several varieties 

 belonging to this group. However, at Arlington the Purple Straw, 

 C. I. No. 1915, has outyielded it in a 5-year test by nearly 3 bushels 

 per acre. Unfortunately, the Purple Straw was discontinued at Col- 

 lege Park in 1912, and consequently data for only five years are 

 available there. It has produced 32.09 bushels per acre, the highest 

 average yield of any variety, at Arlington Farm during the five years 

 from 1910 to 1914. 



The Fultzo-Mediterranean, C. I. No. 1980, a rather popular variety 

 in Maryland and Virginia, has not compared favorably in yield with 

 either Purple Straw or Fultz. At College Park it has yielded nearly 

 as well as the Fultz. Of the 29 varieties that have now been tested for 

 seven years at College Park the Fultzo-Mediterranean ranks twenty- 

 fifth in average yield per acre. The popularity of this variety is due 

 largely to its short, stiff straw and its consequent freedom from 

 lodging. 



Awnless, glumes glabrous, brown. — The leading varieties of this 

 group are the Poole, C. I. No. 1979; Currell (Currell Prolific), C. I. 

 No. 3326; China, C. I. No. 180 and Maryland No. 194; and Red Claw- 

 son (Royal Red Clawson), Maryland No. 188. Of these the China 

 has been the most promising at College Park, while the Poole takes 

 the lead at Arlington. Regardless of group, the China has been the 

 highest yielding wheat tested at College Park. This variety, how- 

 ever, has not yielded especially well at Arlington, where it has been 

 included in the tests only since 1912. Just why a- few varieties are 

 particularly promising at College Park and of little value at Arlington, 

 and vice versa, the writer can not say. The records of the China
