variety, six other pure-line selections, and two commercial varieties of oats grown at the 
Cornell University Agricultural Experiment Station, Ithaca, N. Y., during seven or 
more years in the 11-year period from 1907 to 1917, inclusive.

2 Plant Breeding No. 1571. 
In 1911, several representative unselected commercial varieties 
were added to the experiments at Cornell University, which previous 
to that time had included mostly pure-line selections from hybrids 
and from commercial varieties. Among these were Sixty-Day, 
Silvermine, and Lincoln. The unselected Sixty-Day yielded so much 
less than the selection 5938-1 that it was discarded at the end of 
three years, but the other two varieties are still included. The 
7-year (1911-17) average yield of the Silvermine is 60.3 bushels; of 
the Lincoln, 57.3 bushels; and of the Sixty-Day selection (5938-1), 
53.8 bushels. 
Results in Pennsylvania. 
The Pennsylvania Agricultural Experiment Station at State 
College (15) has included the Sixty-Day variety in its experiments 
since 1907 and the Kherson variety since 1909. The results to and 
including 1910 have been published. The annual and average yields 
of these and seven other varieties in two or more years of the 4-year 
period from 1907 to 1910, inclusive, are shown in Table V. 
As shown in Table V, the Sixty-Day oat during the 4-year period 
from 1907 to 1910, inclusive, outyielded all others at State College. 
The 2-year data on the Kherson indicate that it will do equally as well 
as the Sixty-Day in central Pennsylvania. 
No data on oat varietal tests have been published by the Penn- 
sylvania station since 1911, but Prof. C. F. Noll, associate professor 
of experimental agronomy, has kindly summarized the more recent
