tically all that remain of about 575, most of which have been grown 

 at various times at College Park and Arlington. Of this number, 

 368 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 Carleton in 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 J907. 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. No. 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).

White Bearded X Japanese No.

CI. No. 



3612, Fultz X Eclipse. 



3613, Currell(Currell Prolific) X Dietz. 



3614, Currell X Eclipse. 



3616, C. I. No. 1344 X Jones Winter Fife. 



3617, (Penquite Velvet Chaff X Zim- 



merman) X (Zimmerman X 

 Turkey). 



3618, Jones Winter Fife X C. I. No. 1405. 



C. I. Nos. 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 in 1901 by 

 Mr. Carleton at College Park, Md.; and C. I. Nos. 3612, 3613, and 3614 

 are selections from those made by Mr. Miller at the same place in 



1905. 



GROUPS OF SIMILAR VARIETIES. 



For convenience in comparing 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 in 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. 1 

 It will be noted from Tables III and IV that practically all the vari- 

 eties included in 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.
