Resumo(s)
Corema album (L.) D. Don is the only
species of the genus Corema growing naturally on
sand dunes throughout the Atlantic coast of the Iberian
Peninsula, noted for the white coloured berries and
nutritional value. The lack of information on genetic
studies of the species is one of the most limitations for
the establishment of this species as a new culture.
Thus, this study focuses on the assessment of the
genetic diversity based on inter-simple sequence
repeats (ISSR) molecular markers and morphological
traits. Seventy-one female plants, from four different
sampled sites, were evaluated using six ISSR loci and
eight morphological traits. Fifty polymorphic loci
were detected. The dendrogram based on the UPGMA
method and the principal coordinate analysis classified
the 71 C. album genotypes into distinct clusters. The analyses revealed that accessions from the same
geographical area were generally, but not entirely,
clustered into the same group. Analysis of molecular
variance was higher among populations, than within
populations. The analysis of morphological traits
revealed that there is no distinct separation among
the C. album genotypes grown in different geographic
areas. To our knowledge, this is the first study on the
assessment of the genetic diversity in this species
