of: (1) Well-acclimated home-grown Station seed, (2) seed from 
three northeastern counties, and (3) seed from three southeast- 
ern counties were respectively : 100, 90, and 85. 
The performance of the three Nebraska White Prize corn 
samples secured from different sources and compared at the Ne- 
braska Station is of special interest. Seed which had been 
grown upward of thirteen years by the Experiment Station in 
Lancaster County and by William Ernst of Johnson County 
originated from seed grown by Lee Smith in Washington County. 
The grain yields of corn from the three sources were respectively : 
63.4. 56.2, and 60.4 bushels per acre. Thoro local acclimatiza- 
tion improved it for Experiment Station conditions, whereas, 
seed having been acclimated farther southeast was thereby re- 
duced in productivity for the conditions prevailing at the Ex- 
periment Station. 
LOCAL CORN COMPARED WITH CORN FROM OTHER STATES 
During 1916 and 1917 seed corn w T as obtained from eight 
neighboring states and compared at the Experiment Station 
with the two acclimated local varieties — Hogue’s Yellow Dent 
and Nebraska White Prize. The imported varieties were ob- 
tained from the Experiment Stations of the respective states 
and were acclimated to the conditions prevailing at those Ex- 
periment Stations. One variety was grown from each state 
except Kansas, from which two varieties were tested. Methods 
of testing were the same as in the preceding tests. The results 
are given in Table 32. 
In this test the two local varieties, Hogue V Yellow Dent 
and Nebraska White Prize, yielded respectively 64.0 and 66.1 
bushels per acre with an average of 65 bushels. Of the nine im- 
ported corns, two yielded practically the same as the local, three 
yielded within four bushels, one nine and a half bushels le^s, 
and three more than twenty bushels less. The nine imported 
corns averaged ten bushels less than the local. 
One may conclude from the data that, as a general prin- 
ciple'. locally adapted seed is superior to seed haphazardly im- 
ported. However, the mere matter of distance is not an absolute 
deciding factor in adaptation. It is quite possible to secure 
highly productive seed from a distance, but such introductions 
may meet with disaster unless preceded by local experience with 
the corn. Without such preceding definite experience, the 
rational procedure is to plant only locally grown corn known to 
be adapted. Importation is likely to be successful in propor- 
tion to the similarity of growing conditions of the source and 
destination of the seed.
