Abstract

The annatto (Bixa orellana L.) has great economic importance because it is the only source of natural pigment, bixin, used as a natural dye in the pharmaceutical, textile, dairy, food, beverage, paint and cosmetic industries. This project aims to study the genetic diversity and structure, as well as the reproductive system of local varieties and wild populations of annatto in Brazil. For that, microsatellite primers will be developed for the species by means of a microsatellite-enriched genomic library. Local varieties of annatto will be collected along two axes in the Amazon Basin - north-south (Rio Mamore, Madeira, Negro and White) and west-east (Rio Solimões and Amazonas), in the surroundings of Belém, in Central Brasil (Cuiabá - Porto Velho), as well as wild populations collected in the states of Amazonas, Rondônia and Roraima, to detect possible centers of diversity. The mating system will be studied with a hierarchical design of fruit and individuals from wild and cultivated populations of annatto. Various parameters of genetic diversity and population structure will be estimated. Bayesian analyses, plus cluster and principal coordinate analyses will be conducted in order to evaluate the relationship among the accessions and populations. For the reproductive system study, 10 plants will be used of a wild population and a local variety population, where 20 progenies will be evaluated per plant. From this analysis multilocus and single locus outcrossing rates will be estimated, as well as other related parameters. Information about genetic diversity and structure and the reproductive system will help to guide future prospections for breeding programs, as well as plan for the in situ and ex situ conservation of annatto in Brazil.
