Description

This function creates the fieldbook and fieldplan for an unreplicated design with genotypes randomly allocated on a field with checks following the method described on Westcott (1981).

Usage

1
cd.w(geno, ch1, ch2, nc, ncb = 10)

Arguments

geno

The list of genotypes.

ch1

Name of check 1.

ch2

Name of check 2.

nc

Number of columns.

ncb

Number of columns between two check columns (default is 10).

Details

The genotypes are randomly allocated on a field between equally spaced columns of two alternating check varieties. Check columns are planted each ncb columns where ncb must be even. The specified total number of columns nc is the maximum available number, the actual number could be less.

Value

It returns the fieldbook and fieldplan.
