TESTS OF SELECTIONS OF OATS. 25 
tion of one year, when the selections were grown on a gravelly loam 
soil, the tests have been conducted on a fairly fertile Dunkirk clay 
loam. The highest yields for the six years were obtained from selec- 
tions from hybrids of Sixty-Day x Burt and Sixty-Day X Probsteier 
and from the commercial varieties Welcome and Silvermine. In 
general, the early-maturing strains produced larger yields than the 
medium or late maturing ones. The yields of selections from hybrids 
slightly exceeded the yields of selections from commercial varieties, 
but the difference is practically negligible. Eight selections produced 
an average yield 8.4 bushels to the acre higher than that of eight 
unselected commercial varieties in a 3-year test. The highest average 
yields, 65.1 and 65 bushels, were produced by the commercial variety 
Lincoln and the pure-line selection 123-5 from tjie Welcome variety, 
respectively. 
None of the selections tested at the Pennsylvania experiment sta- 
tion appeared to be superior to the better commercial varieties. The 
best yielding selections were those from the Sixty-Day variety and 
from the hybrids Sixty-Day X Clydesdale and Burt X Sixty-Day. 
At the Arlington Experimental Farm, selections from the Sixty-Day 
variety and from the hybrids Sixty-Day X Clydesdale and Burt X 
Sixty-Day have produced the highest yields. 
At the Virginia experiment station, the highest yields have been 
obtained from selections from the Sixty-Day and Silvermine varieties 
and from the hybrid Burt X Sixty-Day. 
Selections from the hybrids Sixty-Day X Probsteier, Danish Island 
X Asia Minor Kustproof, Burt X Sixty-Day, and Sixty-Day X 
Clydesdale have produced the largest yields at the Ohio experiment 
station. These yields have been slightly exceeded, however, by those 
of certain selections made at the Ohio station from commercial 
varieties. 
The selections tested at the Indiana experiment station do not 
appear to be superior to the better commercial varieties which are 
grown there. The best yielding selection was one from the hybrid 
Burt X Sixty-Day. 
At the Kentucky experiment station, selections from the commercial 
varieties Sixty-Day and Early Champion and from the hybrid Burt 
X Sixty-Day appear to be much better than unselected Burt or other 
commercial varieties which have been tested. 
The tests at the Tennessee and Minnesota experiment stations do 
not supply sufficient data on which to base conclusions.
