Chinese Cherry, generally referring to Prunus pseudocerasus Lindl. species, is one of the most economically important domestic fruit tree in China. To effectively preserve and sustainably utilize this species, a study in genetic diversity and population structure was carried out by the sequence variation of chloroplast DNA trnQ-rps16 intergenic spacers. Polymorphism was calculated among the 200 individuals from 7 local and 10 wild populations across its geographical range in China. The results showed that (1) Total genetic variation in species level was poor (h = 0.478, π = 0.0018). But in the wild populations, it was much higher than that in the local populations (h = 0.565, π = 0.0021 vs. h = 0.152, π = 0.0006). (2) Low levels of genetic differentiation (FSC = 0.19595, P = 0.000), genetic distance (0.00000–0.00297), as well as pairwise Fst value among populations were detected. These results, combined with the insignificant gene genealogy pattern and neutrality tests indicate that Chinese Cherry has relatively low levels of genetic diversity and insignificant population structure. Coancestry might be a combined effect of the reduction in effective population size with the recent demographic bottlenecks and mating systems. The pronounced seed dispersal abilities and relatively high rates of gene exchange are supported by the limited genetic differentiation among populations.
