The Regional Adaptation of Corn in Nebraska 
37 
NATIVE CORN TYPES GROWN OUT OF THEIR HOME 
ENVIRONMENT 
In these tests native seed corn was collected from each of 
the twelve localities within the State previously considered. 
These twelve lots of seed were distributed and grown com- 
paratively in five of the same twelve localities, representing 
a wide range of conditions. Thus, in each test twelve types from 
various parts of the State were compared with each other in 
five different environments, one of the types in each case being- 
native home-grown seed. Approximately 300 plants were grown 
from each type. Care was taken to eliminate the effects of 
variety plat competition by planting extra discard rows between 
unlike types. 
Fig. 13 — Native corn types from nine regional areas of the state, grown com- 
parably in extreme western Nebraska. (Kimball County.) 
Each group of ears is the product of ten successive representative plants 
of each type. The native Kimball County type is the only one which fully 
matured when grown in Kimball County. 
(1) Thurston County corn, (2) Lancaster County corn, (3) Richardson 
County corn, (4) Holt County corn, (5) Kearney County corn, (6) Nuck- 
olls County corn, (7) Cherry County corn, (8) Kimball County corn, (9) 
Lincoln County corn. 
Due perhaps in part to local seasonal abnormalities, and in 
part to the use of relatively few plants, a number of apparent 
inconsistencies occur. However, the nature of the data would 
seem to be such as to justify general conclusions.
