DT_h2: Broad sense heritability calculation.

In sommer: Solving Mixed Model Equations in R

Broad sense heritability calculation.

Description

This dataset contains phenotpic data for 41 potato lines evaluated in 5 locations across 3 years in an RCBD design. The phenotypic trait is tuber quality and we show how to obtain an estimate of DT_h2 for the trait.

Usage

data("DT_h2")

Format

The format is: chr "DT_h2"

Source

This data was generated by a potato study.

####=========================================####
#### For CRAN time limitations most lines in the
