Attalea vitrivir Zona (synonym Orbignya oleifera) is one of the six species of Arecaceae known as ?babassu?. This species is used to make cosmetics, food, and detergents due to the high concentration of oil in the seeds. It is found only in fragmented areas of southern Bahia State and northern Minas Gerais State, southeast Brazil, and this fragmentation has affected both its ecological and genetic characteristics. We evaluated the genetic diversity and population genetic structure of A. vitrivir in six areas of two different regions at the extremes of its geographical range, in order to gain a better understanding of the factors that affect the distribution and partitioning of its diversity. Nine inter simple sequence repeat (ISSR) markers amplified 74 polymorphic bands, resulting in large diversity values (Shannon diversity index, 0.37-0.47; intrapopulation genetic diversity, 0.25-0.34). Analysis of molecular variance (AMOVA) revealed considerable differentiation between sampling sites (30.03%) and regions (12.08%), although most of the diversity was observed within sampling sites (69%). Further differentiation between sampling sites was noted more in the northern region than in the southern region, highlighting the genetic connectivity between the sampling sites within Rio Pandeiros Environmental Protection Area (southern region). The identification of two distinct genetic clusters (K = 2) corresponded to the northern and southern regions, and corroborated the AMOVA results. We suggest that the northern area, outside Rio Pandeiros Environmental Protection Area, must be included in future management plans for this species.

RESUMO - Foi estudado o desempenho dos clones de seringueira (Hevea sp): IAN 717, IAN 873, IAN 3087, IAN 2880, IAN 2388, IAN 4082, Fx 3899, Fx 3864, Fx 3846 e Fx 3810, nas condições ecológicas de Tracuateua, PA. Decorridos oito anos da instalação do experimento, os clones que apresentam melhor desenvolvimento vegetativo são: Fx 3810, IAN 717 e IAN 3087. Destes destaca-se o clone Fx 3810 com 73% das plantas em condições de sangria. ABSTRACT - The performance of the rubber tree clones (Hevea sp.) IAN 717, IAN 873, IAN 2880, IAN 2388, IAN 4082, Fx 3899, Fx 3864, Fx 3846 and Fx 3810 was studied in ecological conditions of Tracuateua. PA. Eight years after the beginning of the experiments, the best clones in vegetativo development were Fx 3810, IAN 717 and IAN 3087, emphasizing Fx 3810, with 73% of the plants in conditions for tapping. |
