# Covariance matrix of the accession means for flowering time.

### Description

Covariance matrices of the accession means for flowering time contained in `means_LD`

and `means_LDV`

, derived from the Atwell *et al.* (2010) data.

### Usage

1 |

### Format

Matrix whose row- and column names are the ecotype-IDs of the accessions contained in
`LD`

and `LDV`

.

### Details

The matrix was computed as in Kruijer *et al.*, Appendix A.
