THE MOST PROMISING SELECTIONS. 
The highest yielding selections were all from commercial varieties, 
as follows: 62-II-19-3 from Sixty-Day, 58.27 bushels to the acre; 
63-1-4 from Burt, 57.7 bushels; 62-II-6-3 from Sixty-Day, 57.37 
bushels; 132-3-1 from Sixty-Day, 57,2 bushels; and 62-II-19-1 and 
132-2 from Sixty-Day, 56.57 bushels. Practically all of the 25 
highest yielding strains in these tests were derived from the Sixty- 
Day or Burt or a combination of these two varieties. Of the selec- 
tions grown in both 1907 and 1908, 17 pure lines of Sixty-Day aver- 
aged 52.55 bushels, 15 strains of Burt averaged 49.39 bushels, and 
16 strains of series 34 averaged 47.74 bushels. These yields were 
in excess of those of all other series except series 8, Danish Island X 
Asia Minor Rustproof, 10 strains of which averaged 48.62 bushels. 
The 25 strains which produced the highest average yields for the two 
years are shown in Table II.

Five of the 10 strains which produced the highest yields for the 
two years were pure-line selections of Sixty-Day, 2 were pure-line 
selections of Burt, 1 was a selection from a hybrid of these two 
varieties, 1 was a selection from a hybrid of Danish Island X Asia 
Minor Rustproof, and 1 was a selection from a hybrid of Sixty- 
Day X Clydesdale. Thus, of these 10 strains, 7 were pure lines 
from Sixty-Day or were selections from hybrids in which that 
variety was a parent, 3 were selections from Burt or from Irybrids 
in which Burt was a parent, and only 1 was unrelated to either of 
these varieties. These 10 strains averaged 56.85 bushels to the acre, 
as compared with an average of 45.04 bushels for the 228 strains 
tested. The 25 highest yielding strains averaged 55.07 bushels to 
the acre. Of these 25 strains 15 were selections of Sixty-Day or
