lineXtester: 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)

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 .

Arguments

replications

Replications

lines

Lines

testers

Testers

y

Variable, response
