Chromatin differentiation between Theobroma cacao L. and T. grandiflorum Schum [PDF]

Genetics and Molecular Biology, 2009
A comparative analysis of mitotic chromosomes of Theobroma cacao (cacao) and T. grandiflorum (cupuaçu) was performed aiming to identify cytological differences between the two most important species of this genus. Both species have symmetric karyotypes, with 2n = 20 metacentric chromosomes ranging in size from 2.00 to 1.19 μm (cacao) and from 2.21 to 1.

Determination of thermophysical properties of cupuassu (Theobroma grandiflorum) dry almonds

The Journal of Engineering and Exact Sciences, 2021
In comparison to cocoa, little has been reported on the drying of cupuassu almonds that can be used to produce cupulate, a chocolate type product. Thus, in this study thermophysical properties of cupuassu dry almonds (moisture = 9.68 % d.b.) were determined as: thermal conductivity (k) of 0.14 kW/(m.K), specific heat (cp) of 2.86 kJ/(kg.K), thermal ...

Phenotypic and genotypic characterization and compatibility among genotypes to select elite clones of cupuassu [PDF]

Acta Amazonica, 2017
The expansion of the genetic base of cultivated materials is an ongoing activity of the cupuassu (Theobroma grandiflorum) breeding program. However, the parents involved need to be genotypically and phenotypically characterized to ensure compatibility of

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...
