Abstract: Reaction of progenies (seedlings) of different Scots pine (Pinus sylvestris L.) populations at the juvenile stage on new climatic and microclimatic conditions was investigated. Differences in the development and adaptation parameters of seedlings of three most distant according io conlinentally (Telšiai, Labanoras, Veisiejai) populations from different geographical regions of Lithuania were revealed and hcritabilily of these traits was established. By variance analysts, the influence of climalic and microclimatic conditions of the environment on the general variation of traits of the seedlings has been found out. Due to a greater trail genetic variation, the selection of families inside populations can be more effective than between populations. In favorable microclimatic conditions (in the greenhouse) variation of growth and biological productivity parameters o!' seedlings is higher, therefore selection would be more effective on population, family and individual levels. Seedlings of the most continental Labanoras population surpass the representatives of Telšiai population formed in the maritime conditions and the southern Veistejai population of medium conlinentally according to growth and biological productivity parameters. The Telsiai population was distinguished by slow growth and lower biological prodtictivily. The survival of seedlings of different populations decreases from the north to the south: the seedlings of Telšiai population formed in the maritime conditions according to this parameter have an advantage over the representatives of the most continental (Labanoras) ami medium continental (Veisiejai) populations. Different adaptation character of individual populations was observed. The general adaptation is typical of Labanoras population, because their progenies grow well in all regions
