Meiotic studies were conducted with F9 plants of the hybrid E. perennis Hitch. .times. Z. mays L. Some vegetative components of fertility (viable seed setting) were also studied. During metaphase I of microsporocytes in plants from both locations the meiotic analysis showed a high rate of bivalent figures, whose values were similar for the 2 localities. The statistical analysis of the vegetative components, plant height, ear length, ear number per plant, seeds per ear and seeds per plant, showed a different arithmetic mean (.hivin.x) for each one. The differences were significant according to the "t" test. Comstock and Robinson's method, adapted to this case, was used for the variance analysis. The heritability for each component was calculated.
