Twenty-four taro (Colocasia esculenta (L.) Schott) samples selected from 40 samples collected at the Northern and North Central provinces of Vietnam based on morphological and RAPD (Random Amplified Polymorphic DNA) data were analyzed genetic diversity with 9 SSR (Simple Sequence Repeat) primers. Total of 67 alleles were amplified from 9 primers. The number of alleles/primer ranged from 1 to 14 alleles, an average of 7.3 alleles. There are 64 polymorphic alleles, accounting for 95.5 percent rate. Polymorphism information coefficient ranged among 24 primers in 24 samples from 0 to 0.87, average 0.54. 15 unique alleles for cultivars and 25 characterized allenles for ecolological regions are useful molecular makers for identifying the local specious taro cultivars and the molecular base of establishing 12 taro cultivars for the core collection for long term conservation.
