由水稻徒長病病株上之Gibberella fujikuroi子囊胞子或分生胞子分離所得之單胞菌株，均有細長之鏽刀型大胞子及鏈生小胞子，為典型之Fusarium moniliforme，再由接種試驗確定各菌株均有高度病原性。
The cultures of Gibberella fujikuroi in this experiment were obtained by single sporeisolation from either perithecia or conidia. Each single ascospore or conidium culture produced the long and slightly curved macroconidia and chains of microconidia typical of Fusarium moniliforme. Pathogenicity tests comfirmed their caused relationship to disease.
Single ascospore or conidium culture did not produce perithecium in pure culture. However, when cultures on favorable medium (4, 9, 10) were mated under suitable culture condition (12, 17, 18), fertile perithecia did develop. When mating was made at random between the single ascospore cultures that were derived from the same ascus or the single conidium cultures, the isolates were about equally divided into 2 mating-types (A, a) From reciprocal crossing tests, the sexuality of tested isolates is known as female, male, or hermaphrodite, respectively.
Heterothallism, however, accounts for the wide genetic variability as recognized in Fusariuin monilifornie that is isolated from rice plant.
