Five years investigation of female and male genotypes in périgord black truffle (Tuber melanosporum Vittad.) revealed contrasted reproduction strategies.

The Périgord black truffle (Tuber melanosporum Vittad.) is a heterothallic ascomycete that establishes ectomycorrhizal symbiosis with trees and shrubs. Small-scale genetic structures of female genotypes in truffle orchards are known, but it has not yet been studied in male genotypes.
