Use of RAPD markers in the germplasm collection of the Cacao Research Center (CEPEC) for genotype identification
The objetive of this work was to compare clones of original accession collection and clones of the CEPEC 500'series, find misidentified material within germplasm and compare duplicates that exist in the Active Bank of Germplasm (BAG) of the Cacao Research Center (CEPEC). Forty accessions were analysed in this work. Nei and Li similarity coefficient were calculated for each comparison. It was possible to characterize some CEPEC clones, such as, CEPEC 507 and CEPEC 509 as being CA1 and RB 40 respectively. Also it is suspected that possible mistakes occur between GS 36 and ICS 95 and can be the same material. In the case of duplicates there was no differences between two lines of five accessions analysed.
