Seed of five corn inbred lines differing in form and type (A: shallow and round form of the dent type MO-17, Os6-2; B: deep and uniform of the semi-flint type B-73, Os84-28 and Os87-24) were tested for their quantity and damaged spots (crown, germ, back side and belly side). Seed damage during the different phases of processing ranged as follows: from 3.8 to 7.2% (harvest), from 36.2 to 52.8% (husking) and from 38.4 to 54.0% (the end of processing). Different parts of seed after processing were damaged as follows: from 17.8 to 29.2% (crown), from 4.1 to 6.7% (germ), from 6.3 to 9.8% (back side), and from 5.7 to 8.3% (belly side). High negative correlation (from r=-0.620 to r=-0.960) between damage of seed and seed quality (germination energy, germination) and high positive correlation between germination energy and germination were found for both lines.
