Multi-environment trial of maize

Description

This dataset contain data on 15 traits assessed in 13 maize hybrids growing in 4 environments. The experimental design was a RCBD with 3 blocks and 1 replications per block. It may be used as example in several functions of metan package.

Format

A tibble with 156 observations on the following 18 variables.

• ENV A factor with 4 levels; each level represents one cultivation environment.

• GEN A factor with 13 levels; each level represents one maize hybrid.

• REP A factor with 3 levels; each level represents one replication/block.

• PH Plant height, in cm.

• EH Ear height, in cm.

• EP Ear position, i.e., the ratio EH/PH.

• EL Ear length, in cm.

• ED Ear diameter, in mm.

• CL Cob length, in cm.

• CD Cob diameter, in mm.

• CW Cob weight, in g.

• KW Kernel weight, in cm.

• NR Number of rows.

• NKR Number of kernels per row.

• CDED Cob diameter / Ear diameter ratio.

• PERK Percentage of kernels.

• TKW Thousand-kernel weight

• NKE Number of kernels per row.
