PROVENANCE TR ĐALS IN TURKEY Forest area of Turkey is 21.18 million hectare, which consists of 26 % of total size of the country. The 44 %, 8.9 million hectare is productive forest and the rest, 56% 11.3 million hectare is unproductive. Unproductive forest area needs to be forested in order to turn into productive forest. However, certain provenances should be used in forestation works. Therefore, which provenance may be used in regional afforestation should be determined, particularly in Turkey, which climatic and soil conditions show great changes from one to another (Simsek et al., 1995). The selection of seed resources is the main factor influencing the productivity of forestation (Urgenc, S., 1982). One of the major objectives of the Ministry of Environment and Forestry and its affiliates is to conserve forest tree species and genetic biodiversity. Provenance trials are important particularly at the initial stage of a tree improvement of program. They provide information about the genetic architecture of the species that is utilized for gene conservation programs, and for maximizing gain for a given area (Isık et al., 2002) There are lots of provenance trail in Turkey. The Turkish Forest Research Institutes are carrying out 6 provenances trials. The main aim of these studies is to determine the best performing provenances for forestations, each geographic zone in Turkey. 1-Turkish Red Pine ( Pinus brutia Ten.) Provenance Trial The Turkish Forest Research Institute established it in 1988 on 26 test sites (one of the test side was established in Cyprus). 50 provenances were tested (47 provenances originating from Turkey, 3 provenances from northern Cyprus) below Table 1 . Most provenances included in the experiment were phenotypically superior stands and had been designated as seed stands for operational planting programs for a particular region. For each provenance, about 30 trees were sampled, cones were bulked and sun dried to extract seeds. One-year old were transplanted to 26 sites in the late autumn of 1988 and in the winter of 1989. The experiments were laid out in the fields as to ‘‘Randomized Complete Blocks Method’’ with 3 replications. 16 seedlings in square in each block initially represented each provenance. Spacing was 1.5 m between in a row and 3 m between the rows. Data were collected from the experimental sites in 1999 when the trees were 10 years old in the field. Survival was assessed s the proportion of surviving trees in each plot. Total height (cm) and diameter at breast height (mm) were measured and the volume was estimated to the nearest dm ³. The coordinator institute of ( Pinus brutia Ten) provenance trial is Southwest Anatolia Forest Research Directory (Antalya). Southwest Anatolia Forest Research Directory were published the 5 and 10 years old results: The five-year results of the experiment as a technical report (Cengiz et al., 1999) Results of provenance study at age 10 on Pinus brutia : Provenance-site interactions and defining breeding zones (Isık et al., 2002).

Pallasiana (Lamb.) Holmboe) Provenance trial The Turkish Forest Research Institute established it in 1984 on 24 test sites. 36 provenances were tested (all the origin were from Turkey) below Table 2. The experiments were laid out in the fields as to ‘‘Randomized Complete Blocks Method’’ with 3 replications. 16 seedlings in square in each block initially represented each provenance. Spacing was 2 m between in a row and 2 m between the rows. 12 test sites are under control.
