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

ABSTRACT: 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. Passport data included site, tree, fruit and seed information. Trees were genotyped using 96 single nucleotide polymorphism markers on a Fluidigm platform. Low heterozygosity was detected in the germplasm in both the Central [observed heterozygosity (H _o ) = 0.295, expected heterozygosity (H _e) = 0.334] and Western Reg
