Abstract	Somatic embryogenesis (SE) should be very effective for propagation of coffee species. Evaluation of indirect somatic embryogenesis (ISE) and direct somatic embryogenesis (DSE) are useful for describing cell proliferation precedes embryogenesis. The research aimed to evaluate the ISE and DSE ability of Coffea canephora Pierre which performed on a great genetic diversity, was carried out at the Nestlé R&D Centre Tours France in cluding the accessions derived from a coffee core collection of Nestle and three clones of ICCRI. Three aspects, namely: SE process, SE diversity and SE stability were evaluated. The results showed that both DSE and ISE process were observed in present study. These results indicated that both SE processes in C. canephora appeared to be independent mechanism. Under given experimental conditions, SE ability depended on the genotype. Diversity for SE ability was observed not only among three genetic groups of C. canephora (Congolese, Guinean, and Conillon), but also within the genetic groups. Moreover, SE was reproducible and stable for explants from cuttings of the given genotype. Interestingly, among three clones of ICCRI, namely BP409, BP961 and Q121 which were used as parents for controlled crosses, showed significant differences suggesting which were possible segregation within their progenies for ISE ability.
