Unreplicated experiment with a grid of checks

Description

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

Usage

cr.w(geno, ck1, ck2, nc = NULL, ncb = 10, serpentine = c("yes", "no"))

Arguments

geno	The list of genotypes.
ck1	Name of check 1.
ck2	Name of check 2.
nc	Number of available columns on the field.
ncb	Number of columns between two check columns (default is 10).
serpentine	"yes" or "no", default "yes".

Value

It returns the fieldbook and fieldplan.
