Coleta, caracterização e avaliação de germoplasma de inajazeiro (Maximiana maripa (Aublet) Drude) do nordeste paraense.

Abstract

The inajazeiro (Maximiliana maripa (Aubl.) Drude) is a palm native to the Amazon which has great economic potential for the biodiesel market , either by managing their natural populations or crops rational. However still makes up the list of non-domesticated species there is little information to stimulate their rational exploitation. This study aimed to collect, characterize and evaluate germplasm inajazeiro northeastern Pará. Data collection was conducted in five municipalities were selected at random arrays at each location to collect bunches. We characterized and local populations, where the matrices evaluated for 17 morphological characters. Data were analyzed using descriptive statistics . Were quantified diversities and differences to phenotypic and genetic populations and dies by means of the 17 traits evaluated and selected as descriptors and molecular markers . Diversity and genetic divergence were obtained by 20 RAPD primers selected for the species using the arithmetic complement of the Jaccard similarity and analyzed by dendrogram . Were collected germplasm arrays inajazeiro, with 25 per site totaling five locations. Matrices and populations showed wide diversity. 88.26 % were selected characters, which are capable of quantifying the phenotypic diversity forming groups , and the UPGMA Tocher without significant loss of information. The 20 RAPD primers generated 252 polymorphic bands. The molecular marker was efficient to quantify genetic diversity and group access and origins UPGMA method. Significant levels of genetic differentiation among provenances were recorded by RAPD markers, however, most of the variation was contained within them . The molecular marker was complementary in explaining genetic diversity , being discordant in relation to phenotypic diversity.
