The variants which were induced by treating Asp. oryzae with 8-hydroxyquinoline and 4-nitroquinoline-nirtogen-oxide were classified into 9 types : restricted, extremely restricted, yellow, floccose, bluish green, sterile, albino, yeast-like and Penicillium-like types. The differences between the parent strain and the variants are as follows : 1)Taxonomic characters.The albino type formed larger conidia thah the parent strain, but the Penicillium-like type smaller conidia. The yeast-like type did not form any conidia.The albino, yeast-like and Penicillium-like types produced more numerous teratologic froms of vesicles and sterigmata than the parent strain.In the length of conidiophore, the bluish green and Penicillium-like types are shorter than the parent strain.2) Cytological characters.The floccose and albino types contained more numerous nuclei in vesicles, sterigmata and conidia than the parent strain, whereas the nuclei in these parts of the bluish green and Penicillium-like types were fewer in number.
