Objective: To study the effect of temperature on the morphological characteristics of Botrytis cinerea (B. cinerea) and its correlated with the genetic variability. B. cinerea is fungus that produces the disease known as grey mould in a wide variet ya polfa angt-ripcauthltougreanlliyc important hosts in many countries.

Results: Results showed that clear morphological differences exist between strains at the temperature of 4, 12 and 28 °C.
