✦ Synopsis

Intervarietal reciprocal Fi's and backcrosses were made between varieties of maize to study the cytoplasmic effects on quantitative characters like grain yield, 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.

Reciprocal crosses between varieties of maize were developed in such a way that the genome of one variety was introduced into the cytoplasm of the other in fractions of 25, 50, and 75 per cent. Cytoplasmic effects on yield, maturity, plant height, and ear height were measured at each of the three nu
