Abstract
Intervarietal reciprocal F1's and backcrosses were made between varieties of maize to study the cytoplasmic effects on quantitative characters like grain yeild, maturity, plant and ear heights, and number of ears per plant. It was found that the expression of all characters except the number of ears per plant was modified by the cytoplasm. Cytoplasmic effects were explained on the basis of the “plasmon-sensitive genes” hypothesis.
