One of the most important problems in fig production is Rosellinia root rot disease caused by Rosellinia necatrix Prill. The disease causes important economic losses by drying fig trees. The disease can be observed on whole trees in orchards by being spread out through soil tillage, irrigation water as well as rain water. There is no registered pesticide against R. necatrix and cultural measurements only decelerate the spread of disease. With this reason, it was aimed in this study to investigate susceptibility levels of some fig varieties and determine the tolerant varieties against this disease. In the study 15 different varieties existing in Erbeyli Fig Research Instiute (E.I.A.I.) were evaluated. These were Kıbrıslı, Kaba İlek, Bostancı, Çakın-2 and Yanako-2 as male fig varieties and Bursa siyahı, Arap inciri, Aydın inciri, Langav, 208, Morgüz, Beyaz Orak, Siyah Orak, Göklop, Kadota as female fig varieties. Above named fig varieties were planted to 25 cm diameter pots containing sterile soil. The experiment was designed according to randomized plot design with 8 replications and Göklop variety was used as positive control which is known as 100 % sensitive to this disease. After isolation of R. necatrix isolates from fig plantations, it was tested for its virulence and this virulent isolate was used for inoculation of varieties used in the experiment. During soil inoculation process R. necatrix was grown on sterile wheat seeds. Each pot was given 40 g of 14 day old R. necatrix culture on 04.03.2009, which was incorporated into 3 cm soil depth around root zone of one year old fig plants. As a result, it was observed that most of the plants were died after about one month (05.04.2009) following treatment and all fig plants were dead two months after treatment (06.05.2009). No plant death was observed in the case of control treatment. R. necatrix was reisolated from death plants. Results of this study showed that all tested cultivars were sensitive to this disease and no resistant fig cultivar was determined.}, number={1}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}
