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.
