The objective of this study was to evaluate the comparative efficiency of different
tests in assessing the vigor of millet seed lots (Pennisetum americanum (L) Leeke). Six lots were
evaluated by the following tests: germination test, cold test, electrical conductivity, emergence on
sand, seedling dry mass, weight of thousand seeds and both emergency and height of seedlings in
the field. The experiment was a completely randomized block design with four replications. The
results showed that: a) the cold test separated millet seed lots into different physiological quality
levels; and b) the seedling dry mass test did not show association with the vigor expression of
millet seeds.
