Abstract. The study was conducted for four years (2016 to 2019) in Olive germoplasm collection at Bouka, Latakia, Syria, to evaluate flower characteristics and sexual compatibility of olive cultivar Coratina under Syrian coast conditions. “Coratina” was characterized by low level of pistil abortion, average number of flowers per inflorescence and good pollen germinablity. ISI of “Coratina” showed that this cultivar was highly self- incompatible. A new threshold depends on flowering load and final fruit set were adapted to evaluate pollinizers. The two autochthonous olive cultivars “Khodeiri” and “Dermlali” were good pollinizers for “Coratina” but with some annual differences in pollination efficiency. Reverse pollination results confirmed that “Khoderi” is inter-compatible with „Coratina“ in both directions. It is suggested to plant “Coratina” in mixed orchards with “Khoderi” because they’re inter-compatible, having regular bearing habit and overlapping in flowering period.
