CEREAL EXPERIMENTS IN MARYLAND AND VIRGINIA. 21 



and Purple Straw at the two places are among the best examples of 

 this variation. 



SOFT WHITE OR AMliKR WINTER. 



Awned, glumes pubescent, white. — The Bearded Winter Fife, C. I 

 No. 1942, has been the most promising of the so-called velvet-chaffed 

 wheats tested at College Park and Arlington. A selection (C. I. No. 

 4204) which is quite similar to it has also been of particular promise 

 at Arlington. Of the several varieties originated by Mr. A. N. Jones, 

 of New York, that have been tested at College Park and Arlington, 

 the Bearded Winter Fife is considerably the best. 



Awnless, glumes glabrous, brown. — The Dawson (Dawson Golden 

 Chaff) C. I. No. 1733, is the only representative of this group included 

 in the tests. Among the soft white winter wheats this variety is of 

 outstanding merit. It is one of the most popular varieties of winter 

 wheat in the eastern United States. At Arlington it ranks third in 

 average yield in a 5-year test and is first in yield of the awnless 

 varieties. At College Park, however, it has not yielded so well, 

 ranking eighteenth in average yield per acre among the 29 varieties 

 that have been tested seven years. Two strains of this variety have 

 been included in the tests at College Park. 



HIGH-YIELDING VARIETIES. 



The varieties which have been high in yield at College Park have 

 not always been high in yield at Arlington, and vice versa. This 

 is well shown in Table V, in which the average yields of the 10 best 

 varieties at each place are shown, with the records of the same varie- 

 ties at the other place for comparison. The integers in the columns 

 headed "Rank" denote the rank of the variety among the total num- 

 ber in the test. The denominators of the fractions in these columns 

 show the number of varieties grown in the same, years as the variety 

 in question, while the numerator shows the rank of that variety. 

 Thus the China was grown only two years at Arlington, when it 

 ranked thirty-second among 36 varieties that were grown the same 

 two years. 



Of the 82 varieties and strains which have been grown at College 

 Park, the 10 highest in order of yield, as shown in Table V, are (1) 

 China, (2) Mammoth Red, (3) Bearded Purple Straw, (4) Turkish 

 Amber, (5) Lancaster, (6) Currell, (7) Bearded Winter Fife, (8) Dietz 

 (C. I. No. 1981), (9) Red Clawson, and (10) Dietz (Md. No. 95). 

 The difference in the 7-year average yield of China and Dietz (Md. 

 No. 95) is 2.46 bushels. Of these 10 varieties, 9 are soft red and 1 

 (Bearded Winter Fife) is a white wheat. Of the red wheats, 6 (Nos. 

 2, 3, 4, 5, 8, and 10) are bearded, with glabrous white chaff; 3 (Nos. 

 1, 6, and 9), are beardless, with glabrous brown chaff. The one white- 

 kerneled variety is bearded, with hairy white chaff. Of the 10
