Cacao is an important perennial crop of humid tropics. Cacao EST sequences, as available in the public domain, were downloaded and made into contigs. Microsatellites were located in these ESTs and contigs using five softwares (MISA, TRA, TROLL, SSRIT and SSR primer). MISA gave maximum coverage of SSRs in cacao ESTs and contigs, although TRA was able to detect higher order (>5-mer) repeats. The frequency of SSRs was one per 26.9 kb in the known set of ESTs. One-third of the repeats in ESTcontigs were found to be trimeric. A few rare repeats like 21-mer repeat were also located. A/T repeats were most abundant among the mononucleotide repeats and the AG/GA/TC/CT type was the most frequent among dimerics. Flanking primers were designed using Primer3 program and verified experimentally for PCR amplification. The results of the study are made available freely online database (http://riju.byethost31.com/cocoa/). Seven primer pairs amplified genomic DNA isolated from leaves were used to screen a representative set of 12 accessions of cacao.
