Technical Abstract: Theobroma cacao, the source of cocoa beans for chocolate, is an important tropical agriculture commodity that is affected by a number of fungal pathogens and insect pests, as well as concerns about yield and quality. We are trying to find molecular genetic markers that are linked to disease resistance and other important economic traits to aid in a marker assisted selection (MAS) breeding program for cacao to ensure a reliable supply of cocoa for the US confectionary industry. Matina 1-6 belongs to the most cultivated cacao type worldwide. Availability of its genome sequence and methods for identifying genes responsible for important cacao traits promise to greatly aid cacao researchers and breeders. A preliminary version of the Theobroma cacao L. Matina 1-6 genome (V0.9) was released to the public in 2010. Our results are important to scientists trying to understand the mechanism of disease resistance and, eventually, to cacao farmers who will benefit from superior disease resistant and more productive cultivars produced through our MAS breeding program.
