Example 11.5.
The following table gives the yield
(q/ha) for eight varieties of wheat tested in four
locations to study the yield stability of the varieties.
Analyze the data, and using Eberhart-Russell
model, find out the best stable variety.
The following is the analysis as per
Eberhart-Russell model using the statistical soft-
ware SPAR1:
