ResumoThe European black pine (Pinus nigra Arn.) is one of the Slovakian pines involved in somatic embryogenesis study and belongs, taxonomically, to he section Pinus of the subgenus Diploxylon (Little & Critchfield, 1969). However, in spite of a common occurrence within the subsection Sylvestris, the species was shown to be sexually incompatible with the two additional species native to Slovakia, e.g. with Pinus sylvestris and Pinus mugo (Vidakovic, 1974; Kormutak & Lanakova, 1988). As a member of the subgenus Diploxylon, P. nigra shares the features postulated by Mirov (1967) for the genetics of a whole subgenus, e.g. a high irregularity in respect to hybridization. According to Vidakovic (1974), of the 13 hybridization attempts performed so far, only 6 interspecific crosses were successful, involving the combinations with taxonomically and geographically distant species such as Pinus resinosa, Pinus heldreichii, Pinus densiflora, Pinus thunbergii, Pinus tabulaeformis, and Pinus halepensis, respectively.
