Sampling included populations from both areas of allopatry and also 14 populations from part of the area of sympatry located in the province of Qu\u00e9bec and covering several thousands of square kilometres. Classification results from RAPD species-specific markers and from a discriminant function based on morphology were compared. Molecular analysis of the allopatric populations indicated a small amount of interspecific gene leakage with no asymmetric directionality to introgression. A high occurrence of hybrid\/introgressant individuals was observed within sympatric populations, suggesting weak reproductive isolation. As expected, the detection of such individuals was more efficient using molecular markers than with morphological traits. The hybrid zone appeared extensive with variable species structure and, in some stands, the main component composed of hybrid\/introgressant trees. Implications for the genecology and genetic management of these species are discussed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Molecular Ecology 6: 725-734 Using species-specific random amplified polymorphic DNA (RAPD) markers and morphological characters, natural hybridization between the closely related black spruce Picea mariana (Mill.)
