Evaluation of plant translocation success based on fitness-related quantitative traits combined with molecular markers may contribute to a finer assessment inbreeding, selective and rescue processes, which might have long-term consequences for population dynamics viability. We investigated fitness (seed germination, seedling viability, juvenile growth mortality) 15 microsatellite loci the first post-translocation seed progeny from two translocated populations Campanula glomerata, an insect-pollinated, self-incompatible perennial herb. examined whether heterosis through admixture, site maternal transplant source origin lineage affect quality in controlled cultivation conditions. Flower production germination transplants was higher one sites, be related differences soil vegetation composition cover. Strong effects were found size, largest producing progeny. The rosette diameter maintained across whole period measured. There inbreeding depression (rather than heterosis) biparental at early stage, also expressed mortality. Our findings highlight that origin, especially when sources consisted small, fragmented remnants, value generations. If persist, they global genetic diversity patterns long term. Further admixture next generations buffer or lead outbreeding depression.
