This work was carried out to evaluate the potential of seed production of 25 accessions of the basic collection of white clover from the United States Department of Agriculture. Through weekly samplings performed from 11/6th/2003 to 3/10th/04 the following variables were analyzed: number of inflorescence/plant, number of flowers/inflorescence, number of mature inflorescence/plant, number of mature legumes/inflorescence, weight of 1000 seeds, and seed yield/plant. It was used a complete randomized experimental design with the accessions individually arranged in five replications. Seed yield of white clover is highly affected by number of inflorescence/plant, number of mature inflorescence/plant, and weight of 1000 seeds. The 53, 2 and 20 accessions differ from the others because of their superiority (7, 68, 19, 79, 58, 3, 15, 75, 64, 50, 33, 13, 59, 38, 28, 80, 54, 29, 31, 23, 22, 27, 65 and 73) of seed production. The accessions 27, 65 and 73 do not produce seeds in the local conditions during the first year of evaluation.
