The determination of the ideal conditions to carry out the germination test on fodder radish seeds is extremely useful to evaluate the quality of seed lots. To determine the appropriate temperature and ideal substrate in the germination evaluation of fodder radish. seeds, from different lots of the CATI AL-1000 and IPR 116 A cultivars were used. They were sown on paper and sand substrates, and the seeds were maintained under six constant temperature regimens (15ºC; 20ºC; 25ºC; 30º C; 35ºC) and one alternating regimen (20ºC-30ºC). The fodder radish seed quality was evaluated by determining the moisture content, germination test, first germination count, germination speed index and health quality. The temperature of 20ºC-30ºC and the sand substrate were the appropriate conditions to carry out the germination test on fodder radish seeds of the CATI AL-1000 and IPR 116 cultivars.
