STATISTICAL ANALYSIS
IBM SPSS Statistic (International Business Machines Corp.) was used for statistical analysis, and principal component analysis was performed between each indigenous population.
To compare the phenotypes of each population, principal component analysis with varimax rotation was performed.
Dendrograms were generated by Ward’s cluster analysis for phenotypic grouping.
Furthermore, one-way ANOVA was performed to determine significant differences in variables between regions.
The tests were performed using Tukey B or Hochberg’s GT2 if the sample size was significantly different, and Dunnet T3 if the isodispersibility was not assumed.
Pearson’s product-moment correlation coefficients were also obtained to measure correlations between variables and field data.
