Studies on characterization of trifoliate hybrids and traditional rootstocks were accomplished in order to know their behavior under tropical conditions in the State of Bahia. Measurements of the height, diameter and weight of the fruits were taken, number of seeds per fruit and per kilo were counted, as well as number of embryos, polyembryony and germination rate and grafting in 34 accessions, mostly introduced from California, USA. The obtained data encourage the use of some trifoliate hybrids, as those from crosses between 'Cleopatra' mandarin (C. reshni hort. ex Tanaka) and 'Sunki' mandarin (C. sunki hort. ex Tanaka) with 'Swingle' and 'English' trifoliate.
