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.
