Multiple Centroid Methodology to analyze genotype adaptability
This study was carried out to propose a modification of the centroid method. The method is modified in thechoice of the ideotype, to be defined according to the researcher's interest, using the bi-segmented regression model, ratherthan based on experimental data, which limit the comparison of g...

This study was carried out to propose a modification of the centroid method. The method is modified in thechoice of the ideotype, to be defined according to the researcher's interest, using the bi-segmented regression model, ratherthan based on experimental data, which limit the comparison of genotypes. To illustrate the method, one trait was simulatedin 25 genotypes in 8 environments. For the simulations and statistical analyses the software package GENES was used. Themultiple centroid is more flexible than the original centroid method, since it can be used according to the researcher's objectiveand the desired recommendation strategy. It is also readily interpretable for recommendation and unambiguous. Besides, thenumber of genotypes of interest can be compared, making a detailed study possible, by separating the genotypes intorecommendation classes. |
