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.
