tically all that remain of about 575, most of which have been grown 
at various times at College Park and Arlington. Of this number, 
36S were made at Halstead, Kans., in 1900, by Mr. Deane B. Swingle. 
These were transferred to College Park in 1901, where about 172 
additional hybrids were made by Mr. Mark Alfred Carletonin that year, 
thus bringing the number up to 540. They were grown and selected 
from year to year, the number being gradually reduced until the fall 
of 1907. At that time those that yet remained, together with about 
35 other hybrids made by Mr. H. A. Miller in 1905 at College Park, 
were transferred to Arlington. 
Finally, in the fall of 1909, when the total number had been reduced 
to less than 50, 11 of the most promising were included in the regular 
varietal tests. The parentage of the 11 selections from hybrids which 
are included in Table III is as follows: 
CI. No. 
3277, C. I. Xo. 1344 X Jones Winter Fife. 
3608. Diehl Mediterranean X Jones 
Winter Fife. 
3609, Shirosawa X Jones Winter Fife. 
3610. Jones Winter Fife X Dawson 
(Dawson Golden Chaff). 
3611, (Crimean X Onigara) X (Reddish 
White Bearded X Japanese Xo. 
1). 
CI.Xo. 
3612, Fultz X Eclipse. 
3613, Currell (Currell Prolific) X Dietz. 
3614, Currell X Eclipse. 
3616, C.I. Xo. 1344 X Jones Winter Fife. 
3617, (Penquite Velvet Chaff X Zim- 
merman) X (Zimmerman X 
Turkey). 
3618, Jones winter Fife X C. I. Xo. 1405. 
C. I. Xos. 3277, 3608, 3609, 3610, 3616, and 3618 are selections 
from the hybrids made by Mr. Swingle at Halstead, Kans., in 1900; 
C. I. Nos. 3611 and 3617 are selections from those made hi 1901 by 
Mr. Carleton at College Park, Md.: and C. I. Xos. 3612, 3613, and 3614 
are selections from those made by Mr. Miller at the same place in 
1905. 
GROUPS OF SIMILAR VARIETIES. 
For convenience hi comparhig the yields of similar wheats and to 
avoid confusion of varietal names in the future, the varieties in 
Tables III and IV have been grouped hi accordance with some of the 
most obvious characters. In this grouping no attempts have been 
made to distinguish between white and amber kernels or between 
white and yellow or red and brown glumes. This classification is 
practically identical with the one published in Farmers' Bulletin 616. x 
It will be noted from Tables III and IV that practically all the vari- 
eties included hi the tests are of the soft red and soft white groups. 
By far the greater number belong to the first group. Several of the 
hard red winter wheats have been tested, but with no marked success.
