We evaluated the genetic variability of a collection of Jatropha curcas germplasm, represented by 93 accessions, using microsatellite markers. Among the 60 markers tested, five of them detected polymorphisms, with a total of 11 alleles and mean of 2.2 alleles per loci. These five markers enabled the quan-tification of genetic variability through estimates of expected (He=0.42) and observed (Ho=0.64) heterozygosity, Shannon-Weaver index (H?=0.62), coefficient of inbreeding (?=-0.44) and the formation of 11 clusters. Simultaneously, 14 accessions randomly sampled among the 93 and represented by seven plants each, were analyzed with these same five markers to quantify the within and between variability. Most of the genetic variation (92.58%) was contained within the accessions. These analyses revealed, for the first time, expressive genetic variability to be explored in this collection. The accessions UFVJC 05, 07, 12, 18, and 53 presented expressive variability among them with potential for the constitution of a base population for the breeding program. |

Theobroma grandiflorum (Willd. ex Spreng.) Schum. is a tree originating in the Amazon forest. In Brazil, it is known as cupuassu and, like Theobroma cacao, belongs to the family of the Malvaceae. The pulp is used by the food industry and the seeds, which are rich in fatty acids, are used in cosmetics. As for cacao, cupuassu cultivation is affected by the witches? broom disease (WBD), caused by Moniliophthora perniciosa (M. perniciosa). Despite its economical value, cupuassu culture lacks genetic information, compromising its plant breeding program development. The aim of this research was to increase molecular knowledge about WBD resistance. The progeny of 168 individuals obtained by crossing two contrasting cupuassu clones (174 and 1074, resistant and susceptible to WBD, respectively) were evaluated. The first consensus genetic map consisting of 1438 markers was produced using genotyping by sequencing (GBS) and genome sequencing of the neighboring species T. cacao (Criollo B97) as reference. The analysis of synteny between T. cacao and T. grandiflorum showed that the average homology between the linkage groups of the two species was 97.2%. A resistance quantitative trait locus (QTL) was identified on chromosome 6 of resistant parent 174 at marker 6M1252980. The phenotypic data associated with that QTL corresponded to observations after natural and artificial infection with M. perniciosa. The biological process associated with this QTL may play a role in resistance and susceptibility to M. perniciosa. MenosTheobroma grandiflorum (Willd. ex Spreng.)
