Monoterpenes were examined in foliage of controlled crosses of lodgepole pine (P. contorta Dougl.). Total terpene production was strongly related to resin canal frequency. Segregation of progeny into classes based on relative amounts (percentages of total monoterpenes) of .beta.-pinene fitted both 1 and 2 locus models for genetic control. Modality in frequency distributions of relative amounts of .beta.-phellandrene could be explained by constraint due to the method of expressing results. Modes in relative amounts of minor monoterpene constituents were due to instrumental detection limits in samples with very low total terpene production.
