Water chestnut Trapa is abundant in lakes of mid-lower reaches of Yangzte River.
- class="label">•
Three taxa (T. quadrispinosa, T. japonica and T. bispinosa) were analyzed with AFLP.
- class="label">•
The three Trapa taxa formed genetically distinct groups.
- class="label">•
Genetic depauperation and evident population structure were found within each taxon.
- class="label">•
Each taxon should be separately preserved based on genetic and geographic origin.
