Trichodema mutants strains T5, T0803, T1010, T1003were cultured in different conditions and media, also in the presence of fungicides at 40 mg/kg (CK or procymidone + chlorothalonil, or maneb or phosethyl-Al) . The pH values of media were 5, 6, 7 and 8 and hyphae were grown at temperatures of 15, 20, 25 and 30 ℃. After being cultured for 3, 4, 5, or 6 days, the strains were transferred at a lower temperature to sporulate (20 ℃) . Obtained data were analyzed statistically, with the orthogonal array and ranges (R) differing dependes on the treatments (R=40.0,42.4, 48.0, 62.8, 107.0).. The results indicated that the most important factor was the nature of the strain (R= 107.0),. while the change in temperature and time of cultivation produced the lowest effect (R= 40.0).. Each factor variance was significant and A 3B 4C 2D 1E 3 was the optimum combined condition, in which strain T1010 grew more quickly and sporulated most.
