Última Conservation implications of the mating system of the Pampa Hermosa landrace of peach palm analyzed with microsatellite markers Genet. Mol. Biol. Picanço-Rodrigues,Doriane; Astolfi-Filho,Spartaco; Lemes,Maristerra R.; Gribel,Rogerio; Sebbenn,Alexandre M.; Clement,Charles R.. Peach palm (Bactris gasipaes) is cultivated by many indigenous and traditional communities from Amazonia to Central America for its edible fruits, and is currently important for its heart-of-palm. The objective of this study was to investigate the mating system of peach palm, as this is important for conservation and breeding. Eight microsatellite loci were used to genotype 24 open-pollinated progenies from three populations of the Pampa Hermosa landrace maintained in a progeny trial for genetic improvement. Both the multi-locus outcrossing rates (0.95 to 0.99) and the progeny level multi-locus outcrossing rates (0.9 to 1.0) were high, indicating that peach palm is predominantly allogamous. The outcrossing rates among relatives were significantly different...

Ano: 2015 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572015000100059 Genetic divergence among populations and accessions of the spineless peach palm from Pampa Hermosa landrace used in the heart-of-palm agribusiness in Brazil Genet. Mol. Biol. Alves-Pereira,Alessandro; Clement,Charles R.; Picanço-Rodrigues,Doriane. Although originally domesticated for its fruit, exploitation of the peach palm (Bactris gasipaes Kunth) in the production of gourmet heart-of-palm has also become an important activity, hence the need for improved material for large-scale production, on employing the Pampa Hermosa landrace as the seed source. In this study 11 microsatellite markers were used to evaluate genetic divergence among 96 elite plants representing four populations of spineless peach palm from the above cited source. Genetic variability was high (H T = 0.82). The low levels of divergence [F ST (0.023), G ST' (0.005)] and the high number of migrants (Nm -3.8 to 52.2) indicated significant interpopulation gene flow. Some of the plants presented high levels of genetic divergence, but...
