摘要：
The genetic structure of 175 genotypes of Theobroma cacao L. was investigated using 27 RFLP/cDNA loci. The number of alleles per locus was never higher than four and a high genetic diversity was found. Criollo genotypes appeared differentiated from Forastero genotypes. A deficiency of heterozygotes was found in all populations and some alleles were fixed in some populations. Within population gene diversity was high. When four morphological groups were considered, Upper Amazon Forastero was the most polymorphic and diverse population. Almost all the alleles of the whole species could be found within this group. Observed heterozygosity was the highest within Criollo and Trinitario populations but a certain proportion of homozygous genotypes was present in all groups.
