genotypic_stability
calculate variance of a genotype across environments.
genotypic_stability(data, trait, genotype, environment, unit.correct = FALSE)
data |
a dataframe containing trait, genotype and environment. |
trait |
colname of a column containing a numeric vector of interested trait to be analysized. |
genotype |
colname of a column containing a character or factor vector labeling different genotypic varieties |
environment |
colname of a column containing a character or factor vector labeling different environments |
unit.correct |
logical, default is |
Genotypic stability (Hanson, 1970) is calculatd based on regression function. Variety with low stability variance is considered as stable. Equation of genotypic stability can be found in vignette file.
