CEEEAL EXPEE1MENTS IN MARYLAND AND VIRGINIA.

(Dietz Longberry) eleventh of 22 varieties grown in all 5 years; Cur- 
rell has been grown only 2 years, with only a fair average yield; and 
Turkish Amber, Red Clawson, and Diefcz (Md. No. 95) have not 
been included in the tests at Arlington. Of the remaining 7 in the 
10 best at Arlington, Poole (C. I. No. 1979) was discarded at 
College Park in 1911 and Purple Straw and Rocky Mountain in 1912; 
Dawson is eighteenth and Fultz twenty-second among the 29 varieties 
grown all 7 years; Stoner has been grown only 3 years, with fair 
yields; and Purple Straw (C. I. No. 1957) has not been included in the 
tests at College Park. 
TESTS OF SELECTIONS IN FIELD PLATS. 
Many selections have been made from some of the leading varieties 
of winter wheat, the object being to develop superior strains. While 
the nursery work along this line has been rather extensive at both 
College Park and Arlington Farm, the number of pure lines that have 
been tested in field plats in comparison with the old strains is com- 
paratively small. At College Park several of the high-yielding pure 
lines of the Fultz and Currell varieties were sown in twentieth-acre 
plats in the fall of 1910. Plats containing a mixture of a half dozen 
or more pure lines of each variety also were sown, as well as plats of 
the original unselected varieties for checks. Unfortunately, the 
Currell checks were not continued after 1911, so that only the yields 
of Currell in the regular varietal test in another field are available for 
comparison. The annual and average yields of these selections and 
of the original unselected varieties at College Park from 1911 to 1914 
are shown in Table VI. At Arlington Farm pure-line selections were 
tested in field plats only in 1913 and 1914, so that data of sufficient 
value to report have not yet been obtained.
