Stress indices for genotype selection
Description
Selection indices for genotypes conducted under stress conditions cited by Ghazvini et al. (2024).
Usage
stind(
GEN,
YS,
YC,
index = "ALL",
bygen = TRUE,
verbose = FALSE,
plot = FALSE,
xlab = "Genotype",
ylab = "Values",
...
)
Arguments
GEN |
The column with the genotypes to be selected. |
YS |
Productivity of the genotype without stress conditions. |
YC |
Genotype productivity under stressful conditions. |
index |
Index to be calculated (Standard 'ALL'). The indices to be used are: 'STI' - Stress Tolerance Index, 'YI' - Yield Index, 'GMP' - Geometric Mean Productivity, 'MP' - Mean Productivity, 'MH' - Harmonic Mean, 'SSI' - Stress Stability Index, 'YSI' - Yield Stability Index, 'RSI' - Relative Stress Index. |
bygen |
Returns the average of each genotype if 'TRUE'. Only in this way it will be possible to plot graphs. |
verbose |
Logical argument. Runs the code silently if FALSE. |
plot |
Plot graph if equal to 'TRUE' (Standard 'FALSE'). |
xlab |
Adjust the title of the x-axis in the graph. |
ylab |
Adjust the title of the y-axis in the graph. |
... |
General ggplot2 parameters for graph customization. |
Value
Returns a table with the genotypes and the selected indices. The higher the index value, the more resilient the genotype.

Examples
library(EstimateBreed)
data("aveia")
#General
index <- with(aveia,stind(GEN,MC,MG,index = "ALL",bygen=TRUE))
#Only the desired index
STI <- with(aveia,stind(GEN,MC,MG,index = "STI",bygen=TRUE))
