Measurements of 17 characters of cones, needles and bark were made on trees from seven provenances in Israel, and analysed by principal components analysis. Four components accounted for 62% of the total variation. Among these components the Bet Meir and Yirka provenances are similar, while the other seed sources differ from each other. There is no evidence of clinal variation; this was confirmed by analysis of four of the original variables, taken separately, although there is significant between-provenance variation. The Rosh HaNiqra seed source tends to have more extreme component values than the others. This may be due to introgression with Pinus brutia or to different selection pressure. © Taylor & Francis Group, LLC.
