Asreml Question

# Asreml Question

```Dear all
I have a field experiment that is designed as an RCBD,and has the
form:

20 columns
________________
|		|
1-4 rows	|    REP  1     |
|_______________|
|		|
5-8  rows	|     Rep 2	|
|_______________|

Now upon inspection of the BLUPs for the rows in REP 1 I clearly have a
linear trend along the columns. That is BLups for Row 1:   -20
Row 2 :  -14
Row 3:    -7
Row 4:    -1
The breeder has an explanation for this.

In order to model this linear trend along the columns within Rep 1. How is
this done in ASREML. I assumed it was of the form:

Yield~ mu c(trt) rep|1\lin(column)                (1)
