Description

Analysis of Line x Tester data for multiple traits containing only Crosses laid out in RCBD or Alpha Lattice design.

Usage

1
ltcmt(data, replication, line, tester, traits, block)

Arguments

data

dataframe containing following variables

replication

replication

line

line

tester

tester

traits

multiple traits of interest

block

block (for alpha lattice design only)

Details

Analyzing the line by tester data of multiple trais only using the data from crosses which are evaluated in RCBD and Alpha lattice design. All the factors are considered as fixed.

Value

Mean

Table of means.

ANOVA

ANOVA with all the factors.

GCA.Line

GCA effects of lines.

GCA.Tester

GCA effects of testers.

SCA

SCA effects of crosses.

CV

Coefficent of Variation.

Genetic.Variance.Covariance

Genetic component Variance and covariance.

Std.Error

Standard error for combining ability effects.

C.D.

Critical Difference at 5 pecent for combining ability effects.

Add.Dom.Var

Additive and Dominance component of Variance.

Contribution.of.Line.Tester

Contribution of Lines, Testers and Line x Tester towards total variation.

Note

The block variable is inserted at the last if the experimental design is Alpha Lattice. For RCBD no need to have block factor.
