The selection of variety with interesting agro-morphological characteristics is particulary important in the integration process of Jatropha in agroforestry systems and yield improvement. Currently, few studies have examined the morphological characteristics of seeds. The present study, therefore, aimedat evaluating the germinative capacity of some Jatropha curcas(L) seeds fromSenegal, Togo, Madagascar, India, Indonesia, China and Kampuchea in relation to their morpho-metric characteristics. The seeds result from a plantation of 50 hain the village of Beud Dieng in the area of Thiès, Senegal. The characterization of seeds related to dimensions, weight, latency time, rate and duration of germination. The seeds have been collected on three types of branches which were: primary ramification (R1), secondary ramification (R2) and tertiary ramification (R3). The collected seeds were germinated in pots filled with sandy clay soil and arranged in randomized complete block design. The results showed that the weight of seeds and their morphology varied according to thedifferent provenanceand the position of the branches. The interaction between these two factors was very highly significant (p = 0,000) at level of 5%. The African provenance (Senegal and Togo) had bulkier seeds and a better level of germination. Whatever the source, the morphological parameters of seeds were higher on the branches of order 2 (secondary ramification). The relation between the morphology of seeds and the germinative capacity was well established
