RESUMO

Haploid strains of Aspergillus nidulans were used in na attempt to study the variation in the production of cleistothecium. Six strains were analysed. From these strains 5 produced cleistothecia. Erratic variation in the production of cleistothecium was observed. Colonies originated from strains which produce cleistothecium segregate into cleistothecial and acleistothecial forms. The number of cleistothecieal and acleistothecial colonies showed variation under several conditions. A heterokaryon transfer teste indicated the participation of an extrachromosomal factor in the control of the difference between the cleistothecial and acleistothecial states. The genetic control of the formation of cleistothecium is discussed
