PREMISE OF THE STUDY
Microsatellite primers were developed for taro (Colocasia esculenta) to investigate its population genetics and evolutionary history through germplasm improvement. •
METHODS AND RESULTS
Nineteen microsatellite loci were identified in three populations. The number of alleles per locus ranged from two to seven, with a mean of 4.68. The observed and expected heterozygosities ranged from 0.231 to 0.820 and from 0.126 to 0.742, respectively. •
CONCLUSIONS
These new genetic markers will be useful for the study of taro germplasm management and population evolution in southwestern China.
研究前提
开发了用于芋艿（Colocasia esculenta）的微卫星引物，通过种质改良来研究其种群遗传学和进化历史。
方法和结果
在三个群体中鉴定出 19 个微卫星位点。每个位点的等位基因数范围从两个到七个，平均值为 4.68。观察到的和预期的杂合度分别在 0.231 到 0.820 和 0.126 到 0.742 之间。
结论
这些新的遗传标记将有助于研究中国西南部的芋艿种质管理和种群进化。
