Multi-environment trial of wheat in Sweden in 2016.

Usage

data("buntaran.wheat")

Format

A data frame with 1069 observations on the following 7 variables.

zone: Geographic zone: south, middle, north
loc: Location
rep: Block replicate (up to 4)
alpha: Incomplete-block in the alpha design
gen: Genotype (cultivar)
yield: Dry matter yield, kg/ha

Details

Dry matter yield from wheat trials in Sweden in 2016. The experiments in each location were multi-rep with incomplete blocks in an alpha design.

Electronic data are from the online supplement of Buntaran (2020) and also from the "init" package at https://github.com/Flavjack/inti.
