ltcmt | R Documentation |

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

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

`data` |
dataframe containing following variables |

`replication` |
replication |

`line` |
line |

`tester` |
tester |

`traits` |
multiple traits of interest |

`block` |
block (for alpha lattice design only) |

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.

`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. |

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