Protoplasts of cycloheximide-resistant strains from Aspergillus oryzae IFO 5239 were fused with those of kabicidin-resistant strains from Aspergillus niger IFO 4407. By nuclear staining in conidia, it appeared that all of the fusant conidia had two kinds of nuclei. Small nuclei seemed to be derived from A. oryzae and large nuclei seemed to be derived from A. niger. However, three types of antibiotic resistance were shown among the conidia of fusants. Almost all were kabicidin resistant. Conidia of fusants were multinuclear and had various DNA contents and various sizes. By the comparison with the growth rates of parental strains, the growth rates of A. niger were superior to those of A. oryzae. The inclination in the distribution of antibiotic resistance of fusant conidia seemed to owe more to the differences of growth rates between parental strains that the influence of the multinucleate nature of a parental strain.
