Abstract : A reliable cryopreservation technique was developed for friable embryogenic callus lines of Hevea brasiliensis. The technique included a callus pre-culture on a maintenance medium containing 1 mM CaCl2 prior to cryopreservation to promote postthaw callus growth recovery. Application of this cryopreservation technique on a sample of 39 callus lines, showed a high percentage of post-thaw lines growth recovery and subsequent maintenance of embryogenic and regeneration competences. Today, all the lines obtained including transformed lines were cryopreserved using this procedure. Data base has been developed for management of cryopreserved stocks. (Résumé d'auteur)
