Abstract
THE production of vegetative diploid strains in culture was first reported in Aspergillus nidulans1. The diploid nuclei were produced by rare nuclear fusion in a balanced heterokaryon formed from two different uninucleate colour mutants. Diploids have been synthesized in many other species of fungi by modifications of this method, and used chiefly for the study of mitotic segregation2. The spontaneous frequency of diploid formation in fungi varies from 10−5 to 10−8 in the Ascomycetes and Fungi Imperfecti, and from 10−3 to 10−4 in the Basidiomycetes3.
