R: Line x Tester Analysis

lineXtester {agricolae} | R Documentation

## Line x Tester Analysis

### Description

It makes the Line x Tester Genetic Analysis. It also estimates the general and specific combinatory ability effects and the line and tester genetic contribution.

### Usage

    lineXtester(replications, lines, testers, y)

### Arguments

`replications` | Replications
`lines` | Lines
`testers` | Testers
`y` | Variable, response

### Details

ANOVA with parents and crosses
ANOVA for line X tester analysis
ANOVA for line X tester analysis including parents
GCA Effects: Lines Effects, Testers Effects and SCA Effects.
Standard Errors for Combining Ability Effects.
Genetic Components.
...
Proportional contribution of lines, testers and their interactions to total variance

### Value

return anova(formula = Y ~ Replications + Treatments).
where the Treatments contains parents, crosses and crosses vs Parents.
The crosses contains Lines, Testers and its interaction .
