ABSTRACT

In view of the scarcity of data available in the literature, especially in Brazil, concerning the genetics of Trichometasphaeria turcica, a comparative study of monoconidial and mono-ascosporic isolates of the fungus was conducted to determine the genetics of the sexual compatibility pattern starting from crosses in vitro.
The exact determination of the compatibility group is hampered by the great genetic heterogeneity of the nuclei present in the multinucleate conidia. The results of monoconidial crosses and the physical factors that may be operating for successful crossing are discussed.

Keywords: sexual; compatibility; Trichometasphaeria turcica.
