Notes:

  1. Seedlots 712, 713, 714, 715, 716, 183, 118, and 366 are local controls, and do not form part of the international seed exchange under the international programme.
  2. The field assessment revealed that what should be the Doi Inthanon provenance of P. kesiya is in fact P. tecunumanii. As the seed sources could not be further identified, it has been omitted from the analysis.
  3. The Guanaja provenance of P. caribaea var. hondurensis and the Coto Mines provenance of P. kesiya are only in the Aek Nauli trial, not in the Habinsaran trial.
  4. Eucalyptus grandis has been included as a local control in both trials. The Eucalyptus plots in the Aek Nauli trial have been cut down, and hence Eucalyptus is only in the Habinsaran trial. The plots have been assessed, but not included in the statistical analysis.
  5. The Simao provenance of P. kesiya is only present in the Habinsaran trial, and only in one of the four replicates. This plot has been assessed, but the provenance has not been included in the statistical analysis.
