N2  - The gametic sterility, the long duration of the young stage, species incompatibilities and especially the high rate of polyembryony are common difficulties in citrus breeding. Polyembryonic cultivars usually contain a zygotic embryo at the earlier stages of seeds. By embryo rescue techniques, the zygotic embryos further development can be secured. In this study, suitable GA3 concentration (0; 1; 2 mg/L) and embryo development stages (days after pollination 105, 115, 125) for embryo germination at Cleopatra mandarin x Carrizo citrange and Cleopatra mandarin x ‘Flying Dragon’ trifoliate orange were examined. The results indicated that the highest germination rate was observed from 2 mg/L GA3 containing M&T media which were harvested 115 days after pollination. The highest germination rates of embryos taken 115 days after pollination and germinated on 2 mg/L GA3 containing media in Cleopatra mandarin x Carrizo citrange and Cleopatra mandarin x Flying Dragon were obtained with 65% and 30%, respectively
