Green cuttings root formation of olive varieties which are found National Olive collection is studied in project real cuttings that are taken from 83 olive varieties form as project material. Applying Randomised Blocks Design in trial,three replicates dwelt on every variety and every replicate consisted of 50 cuttings. So, in as applying period 83 varieties x 3 replicates x 50 cuttings=12450 cuttings were used. Treating 4000 ppm IBA hormone for 5 seconds, cuttings planted to perlite and rooting beds where are controlled humitidy and heat in the greenhouse conditions. At the and of rooting period for 90 days, Uprooting cuttings, the percentage of rooted cuttings are estimated for every variety and replicate. Transfering rooted cuttings in to 13x17 cm. dimension of small polyethene bags, it was determined “take” rate at the end of the development period. Test which was applied twice a year during spring and autumn for two successive years showed following results; Rooting percentages show a vast variation between %0,25 and %90 connected with varieties. The highest rooting ratio belonged to Görvele variety, Conversely, the lowest rooting ratio belonged to Trabzon Yağlık and Çilli varieties. Because of poor rooting ability of Trabzon yağlık, Samon yağlık, Çelebi, Çilli, Büyük topak ulak, Tesbih çelebi , Yağlık çelebi varieties, they should be produced by means of grafting. There are distinctions from the point of view of rooting percentage between spring period and autumn period. Rooting percentage of autumn period is higher than spring period. The conclusion can be reached that there is a positive correlation between; Rooting percentage - the number of root, rooting percentage - “take” rate and the number of root + “take” rate as statistics.
