In sommer: Solving Mixed Model Equations in R

Full diallel data for corn hybrids

Description

This dataset contains phenotpic data for 36 winter bean hybrids, coming from a full diallel design and evaluated for 9 traits. The column male and female origin columns are included as well.

Usage

data("DT_fulldiallel")

Format

The format is: chr "DT_fulldiallel"

Source

This data was generated by a winter bean study and originally included in the agridat package.
