geno |
The list of genotypes. |
check |
The list of checks to repeat in each incomplete block (optional). |
nb |
Number of complete blocks. |
k |
Size for the incomplete blocks. |
nc |
Number of available columns on the field for each complete block . |
breakib |
If incomplete blocks should be broken in more than one
row, default |
serpentine |
|
alongside |
|
The genotypes are randomly allocated on a field following an alpha
(0,1) design. In this design each block is a complete replication that is
divided into s
incomplete blocks of size k
. For any pair of
genotypes, the number of times they concur into the same incomplete block
is 0 or 1 (hence the name of the design). There are 4 options for this design:
nb = 2
and k <= s
.
nb = 3
, s
odd, and k <= s
.
nb = 3
, s
even, and k <= s-1
.
nb = 4
, s
even and not a multiple of 3, and k <= s
.
The blocks and incomplete blocks are disposed alongside the rows.
It returns the fieldbook and fieldplan.
