The genetic diversity of 255 taro (Colocasia esculenta) accessions from Vietnam, Thailand, Malaysia, Indonesia, the Philippines, Papua New Guinea and Vanuatu was studied using AFLPs. Three AFLP primer combinations generated a total of 465 scorable amplification products. The 255 accessions were grouped according to their country of origin, to their ploidy level (diploid or triploid) and to their habitat—cultivated or wild. Gene diversity within these groups and the genetic distance between… Expand
Genetic diversity of taro (Colocasia esculenta (L.) Schott) in Vanuatu (Oceania): an appraisal of the distribution of allelic diversity (DAD) with SSR markers
TLDR
The use of this set of microsatellite markers along with the molecular dataset obtained from this study as effective tools to monitor the diversity and evolution of taro in the future are discussed. Expand
Characterisation of taro (Colocasia esculenta (L.) Schott) genetic resources in Southeast Asia and Oceania
TLDR
The results of these studies indicate that the genetic base of the cultivars is narrow, which implies that crosses between accessions originating from only one country are not desirable and it is appropriate to cross cultivars from both genepools. Expand
Genetic Diversification and Dispersal of Taro (Colocasia esculenta (L.) Schott)
TLDR
The diversity and diversification of taro accessions from nineteen countries in Asia, the Pacific, Africa and America were investigated, with the highest genetic diversity and number of private alleles in Asian accessions, mainly from India. Expand
Study of Genetic Diversity in South Indian Taro (Colocasia esculenta (L.) Schott.) Using Random Amplified Polymorphic DNA Markers
TLDR
The phylogenetic tree generated using UPGMA cluster analysis revealed that genetic diversity in taro was correlated with the wild and the cultivated forms and may be suggestive of agro-ecological and sexual separation between them. Expand
Genetic diversity analysis in South African taro (Colocasia esculenta) accessions using molecular tools
TLDR
The ITS2 secondary structure had one common motif present in all 25 accessions suggesting that it could be used as a taxonomic marker for taro suggesting the high genetic diversity provides taro breeders a selection of parents for the improvement of taro. Expand
Nature of taro (Colocasia esculenta (L.) Schott) genetic diversity prevalent in a Pacific Ocean island, Vanua Lava, Vanuatu
TLDR
Folk beliefs about origin at least for three pairs of mutants are confirmed, and genetic results showed no clear groupings according to geographic origin or habitat of morphotypes and stated that the diversity found within the village was comparable with the overall diversity found in Vanuatu.

Genetic Structure and Diversity of East African Taro [Colocasia esculenta (L.) Schott]
TLDR
This study utilizes six microsatellite primers to analyze five populations of taro from three different regions of East Africa to establish a regional collection that will be conserved and ensure a broad genetic base for available varieties and enable development of improved varieties through breeding programmes. Expand
Genetic Diversity in Taro (Colocasia esculenta)
TLDR
Taro is a neglected crop in terms of recent advances in molecular biology, with only a limited number of studies utilizing next-generation transcriptome and genome sequencing; however, recent genotyping-by-sequencing (GBS) approaches promise to improve the understanding of taro genetics. Expand
