crodesign {predhy}

Generate Mating Design

Description

Generate a mating design for a subset of crosses based on a balanced random partial rectangle cross-design (BRPRCD) (Xu et al. 2016).

Usage

crodesign(d, male_name, female_name, seed = 123)

Arguments

d

an integer denoting 1/d percentage of crosses to be evaluated in the field.

male_name

a character string for the names of male parents.

female_name

a character string for the names of male parents.

seed

the random number, default is 123.

Value

A data frame of mating design result with three columns. The first column is "crossID", the second column is the "male_Name" and the third column is the "female_Name".

Examples

## generate a mating design with 100 male parents and 150 female parents
## for 1/d = 1/50 percentage of crosses to be evaluated in the field.
## the total number of potential crosses is 100*150 = 15000.
## The number of crosses to be field evaluated is 15000*(1/50) = 300.
