초록

Intergeneric hybrids formed between Aspergillus oryzae var oryzae and Penicillium verruculosum F-3 were obtained by nuclear transfer technique. Several auxotrophic mutants isolated fromconidio-spores of the two strains mutagenized with ultraviolet and N-methyl-N-nitrosoguanidine. Optimal conditions for formation of intergeneric hybrids were investigated. Frequencies of hybrid formation by nuclear transfer were 3$\times $10$^{-5}$ $~$1$\times $10$^{-5}$. From observation of genetic stability, conidial size, DNA content, nuclear stain, it was suggested that their karyptypes are aneuploid. The hybrid posses the 1.3$~$2.2 fold higher amylase activities than those of parental strains. It was also revealed that some hybids had different isozyme patterns compared to those of parental strains by amylase activity assays.
