In mitochondrial DNA (mtDNA) heteroplasmy in <i>Drosophila</i>, we previously reported that mtDNA was selectively transmitted depending on temperature (Matsuura et al., 1991). To investigate the effects of nuclear genome on the temperature-dependent transmission, two sets of heteroplasmy were constructed by germ-plasm transplantation, and changes in the relative proportion of two types of mtDNA were examined at 19°C and 25°C. In heteroplasmy possessing <i>D. melanogaster</i> and <i>D. mauritiana</i> mtDNA, two different nuclear genomes of <i>D. melanogaster</i> were examined after reciprocally substituting the nuclear genomes. In heteroplasmy possessing <i>D. simulans</i> and <i>D. mauritiana</i> mtDNA, nuclear genomes of <i>D. melanogaster</i>, <i>D. simulans</i> and <i>D. mauritiana</i> were used. For each set of mtDNA combination, the modes of temperature-dependent transmission of mtDNA differed according to the nuclear genome used. From these and our previous results (Matsuura et al., 1991; Tsujimoto et al., 1991), it is clear that the temperature-dependent transmission of mtDNA is affected by nuclear genome. This suggests that the nuclear genome is involved in determining the temperature-dependency of mtDNA transmission.<br>
