The monoterpene composition of the needle oil of Pinus oocarpa Schiede ex Schltdl. and Pinus caribaea Morelet growing in Zambia were studied by means of GC-MS. P. oocarpa needle samples were taken from 29 trees representing different clones in a seed orchard and from 43 trees in a commercial plantation in 1980. The P. caribaea needle samples were collected from 17 clones in a seed orchard.
Nine compounds were positively identified in the monoterpene fraction of P. oocarpa and eight in that of P. caribaea. The amounts of these compounds showed marked tree-to-tree variation and the sample trees were screened into distinct groups on the basis of the variation. The results give a basis for selection in favour of pest resistance and turpentine yield.
