The diversity and genetic relationships among two accessions of tall coconut palms col-lected in Brazil and seven accessions introduced from different geographic regions of the world were analyzed using 25 microsatellite primers, 19 of which were polymorphic and detected between 4 and 10 alleles per locus, with an average of 6.57. The observed and expected heterozygosity ranged from 0.25 and 0.40 in the Rennell Islands Tall (RIT) accession to 0.54 and 0.62 in the Polynesian Tall (PYT) accession. The analysis of genetic structure resulted in the formation of five distinct groups. The first group was formed by the accessions Brazilian Tall ? Praia do Forte (BRTPF), Brazilian Tall ? Merepe (BRTMe) and West African Tall (WAT); the second group consisted of Malaysian Tall (MLT); the third group of RIT; the fourth group of Vanuatu Tall (VTT); and the fifth group of Rotuman Tall (RTMT), Tonga Tall (TONT) and PYT. The dendrogram based on the nearest-neighbor method detected the formation of two main groups and five subgroups, indicating that the genetic relationships of the accessions are based on their geographic regions of origin. The analyses revealed genetic relationships between the accessions collected in Brazil and the accession from Africa, and among palms from South East Asia and the South Pacific, con firming the common origin of these accessions. The information obtained in this study can guide decisions on germplasm conservation activities and the efficient selection of geneti cally divergent parents for use in coconut breeding programs in Brazil, which are attempting to select for disease resistance, mainly to lethal yellowing, among other characteristics.

The participation of the stakeholders in environmental debates has favored the discussion of new themes locally, nationally and globally. Thus, the environment has progressively achieved more legitimacy among countries. It is important to point out that societal, organizational and individual behaviors represent a critical factor of the global climatic change, particularly, in brazilian industrial and agribusiness development. The conflicts of bioenergy related to food dilemmas put some questions: Is the economic dimension the only preoccupation for this dilemma? How could dialogue between stakeholders in agribusiness contribute for the problems of climate change with the use of bioenergy? The objective is to propose a framework for better comprehension of the participation of agribusiness stakeholders in the bioenergy Vs. Food Production Dilemma in the context of climate change. |
