Genetic diversity and ancestry of cacao ( L.) in Dominica revealed by single nucleotide polymorphism markers.

Cacao ( L.), an introduced tree crop in Dominica, is important for foreign exchange earnings from fine or flavour cocoa. The genetic structure of farmed cacao in Dominica was examined to identify varieties for conservation, breeding, and propagation to improve their cocoa industry.

Development of a core SNP panel for cacao ( L.) identity analysis.

Single nucleotide polymorphisms (SNPs) are preferred markers for DNA fingerprinting and diversity studies in cacao ( L.). Yet, a consensus SNP panel with a minimum number of SNPs for optimal identity analysis is unavailable for cacao.

Morphological and genetic diversity of cacao ( L.) in Uganda.

Cocoa is among the top foreign exchange earners in Uganda's agriculture sector and has benefitted the livelihood of farmers involved in production. Although cacao cultivation was adopted in the early 1900s, little is known about the on-farm diversity of the crop. A total of 125 cacao landraces were surveyed from eight districts in the Central and Western Regions to evaluate the morphological and genetic diversity of cacao in Uganda.

Association mapping of seed and disease resistance traits in Theobroma cacao L.

Microsatellite and single nucleotide polymorphism markers that could be used in marker assisted breeding of cacao were identified for number of filled seeds, black pod resistance and witches' broom disease resistance. An association mapping approach was employed to identify markers for seed number and resistance to black pod and witches' broom disease (WBD) in cacao (Theobroma cacao L.).

Genetic diversity and parentage in farmer selections of cacao from Southern Sulawesi, Indonesia revealed by microsatellite markers.

Indonesia is the third largest cocoa-producing country in the world. Knowledge of genetic diversity and parentage of farmer selections is important for effective selection and rational deployment of superior cacao clones in farmers' fields. We assessed genetic diversity and parentage of 53 farmer selections of cacao in Sulawesi, Indonesia, using 152 international clones as references.

Chloroplast microsatellite primers for cacao (Theobroma cacao) and other Malvaceae.

Premise Of The Study: Chloroplast microsatellites were developed in Theobroma cacao to examine the genetic diversity of cacao cultivars in Trinidad and Tobago.

Methods And Results: Nine polymorphic microsatellites were designed from the chloroplast genomes of two T. cacao accessions.
