Abstract
For the classification of 531 isolates of Fusarium moniliforme from infected rice plants, five criteria were employed for clarifying the mycological difference from I to IV based on host symptoms, conidial formation, septate of macroconidia, color of mycelium on the culture, and fungicide response. Four strains I, II, III, and IV were detected and Strain IV was the most prevalent one. Based on mycological characteristics, macroconidia with 6 or 7 septate were mostly produced by Strains I and II. Four septate macroconidia were mostly formed by Strain III while Strain IV mostly formed 3 septate macroconidia. Strain I was reddish purple (5RP 5/4) on both the bottom and the surface of the media. Strain II produced reddish purple(5RP 3/2) on both the bottom and the surface of the media. Strain I produced mostly macroconidia in pionnotes on the media surface while Strain II produced mostly microconidia in pionnotes on the media surface. Both of Strain III and IV produced mostly macroconidia in sporodochia on the surface of the mycelium. Strain IV was less reduction of germination and caused abnormal elongation of all parts of the plants, but did not kill the plants in nursery boxes. Strain III killed fewer plants than Strain IV. As above results, isolates of F. moniliforme were classified into four strains I, II, III, and IV, on the basis of five criteria.
