Elephant grass is a grass with one of the highest potential for milk and beef production under grazing conditions. However, its utilization is limited due to the dissemination method that uses stems for pasture formation. The interespecific cross with pearl-millet, aims to obtain seeds of bigger size to facilitate the propagation of elephant grass. The objective of this paper was to verify the germination potential of different progenies of elephant grass hexaploid seeds to confirm the viability of this dissemination method. The experiment was carried out at Embrapa Gado de Leite, evaluating 78 half-sib progenies of hexaploid elephant grass in a complete randomized block design with three replications and 100 seeds per experimental unit. Three counting of germinated seeds were done in each experimental unit every seven days. Significant differences were observed between progenies showing the existence of variability in the potential for the dissemination when using seeds originated from half-sib progenies of hexaploid elephant grass. The range of variation for seed germination was 48,67%. The progenies were divided into six groups by the Scott-Knott test and the progenies 64, 53, 19, 2, 45, 72, 10 and 77 presented the best germination rate, with values above 35%.
