Mushroom breeding and selection (development, evaluation and maintenance of new genotypes) have progressed at different rates for different species. Breeding high-yielding strains has traditionally been accomplished by trial and error, and large numbers of hybrid can be obtained by pairing monosporic cultures. In this study, ten monosporic cultures of Pleurotus sajor-caju, P. flabellatus, P.florida and Lentinula edodes in all combination on MEA plates and incubated at 25 ◦C for two weeks. Mycelial plugs taken from the junction zones between colonies were examined for the presence of clamp connections. Hybridisation is said to have taken place in the presence of the clamp connection structure. Our preliminary results showed that mating between P. sajor-caju and P. flabellatus was most compatible where 7% showed the presence of clamp connection. However, the rest showed lower hybridisation percentage whereby mating between P. sajor-caju and P. florida were 4% positive for the presence of clamp connection, followed by P. sajor-caju with L.. edodes (3%) and P. flabellatus with L. edodes and P. florida with L .edodes (2% each.). Keywords : Hybridization, monokaryon, basidiomycetes, clamp connection
