Descripción :	The rambutan (Nephelium lappaceum) is an exotic fruit with great market potential in Brazil. However, there are few available informations about plants with potential for cultivation, because great morphologic variation is observed among plants and for consequence, little uniformity in the orchards and in the fruits. This research had for objective to evaluate the genetic diversity of a collection of rambutan plants obtained by seeds through morfo-chemical analyses of plants and fruits and by fAFLP molecular markers, to indication of promising materials to be used in new plantings of the culture in the São Paulo State. Was verified that both markers, morphologic and molecular, were efficient in the distinction of varieties, showing the presence of genetic variability among the plants of this study. Was also verified that the materials A51 and B03 presented a larger group of desirable characteristics for new cultivations of the fruitful.

Este trabalho teve por objetivo avaliar a diversidade genética de uma coleção de plantas de rambutan obtidas por sementes através de análises morfo-químicas de plantas e frutos e por marcadores moleculares fAFLP, para indicação de materiais promissores a serem utilizados em novos plantios da cultura no Estado de São Paulo. Verificou-se que tanto os marcadores morfológicos como os moleculares foram eficientes na distinção de variedades, demonstrando a presença de variabilidade genética entre as plantas deste estudo. Verificou-se também que os materiais A51 e B03 apresentaram um maior conjunto de características desejáveis para novos cultivos da frutífera. Nephelium lappaceum L. genetic diversity by morphologicaland molecular characterizationAbstractThe rambutan (Nephelium lappaceum) is an exotic fruit with great market potential in Brazil.However, there are few available informations about plants with potential for cultivation, becausegreat morphologic variation is observed among plants and for consequence, little uniformity in theorchards and in the fruits.
