Regression-based stability analysis using the Eberhart and Russell (1966) model.
ge_reg(.data, env, gen, rep, resp, verbose = TRUE)
.data | The dataset containing the columns related to Environments, Genotypes, replication/block and response variable(s) |
---|---|
env | The name of the column that contains the levels of the environments. |
gen | The name of the column that contains the levels of the genotypes. |
rep | The name of the column that contains the levels of the replications/blocks |
resp | The response variable(s). To analyze multiple variables in a
single procedure use, for example, |
verbose | Logical argument. If |
An object of class ge_reg
with the folloing items for each variable:
The data with means for genotype and environment combinations and the environment index
The analysis of variance for the regression model.
The estimated coefficients of the regression model.
