Table 2 Comparison of genetic diversity and clonal diversity parameters based on ISSR for local populations of Zingiber zerumbet at the microgeographic scale with that of selfing Z. corallinum and outcrossing Z. nudicarpum. (The data of Z. corallinum and Z. nudicarpum utilized in this study are from Huang et al. [44].)
