Variation in cone size, seed number per cone, seed morphology and seed germination characteristics of Pinus sylvetsris L., and its relation to stand conditions was analyzed. Data were collected from P. sylvestris natural seed stands in four provinces of Northern Mongolia, namely, Selenge, Khuvsgul, Khentii and Tuv provinces. Cone morphological characteristics as well as their seed production were measured. Seeds were extracted from the collected cones, seed traits were measured and their germination characteristics was examined. The study results revealed that two sources, namely Yangiin ar area, Binder district, Khentii province and Ikh-Ulunt area, Bugant district, Selenge province showed the best and stable performance in all measured traits of seed quality, cone and seed morphological traits, whereas Mukhar dukhum area, Selenge province were lowest in all the measured traits among the studied seed populations. These seed sources are recommended for better productivity and vigorous seedlings in Mongolia, particularly in the research site of this study.
