Abstract(s)
The variability of 43 open-pollinated
populations of maize (Zea mays L.), representing a
wide range of ecological conditions on the Archipelago of Madeira, was evaluated based on the morphological and reproductive traits. Individual data of 41
traits related to earliness, plant and tassel structure
and the shape of the ear and grain were analysed
using multivariate analysis. The populations belonging to two major maize varieties were grouped into
four groups by their degree of dissimilarity, based on
discriminant analysis. The dissimilarity of these
groups was confirmed by the values of the Tukey
test. The racial rank of these groups was proposed
and a brief description of the maize landraces was
presented. This work represents the first morphological characterization and analysis of diversity of
maize germplasm for the Archipelago of Madeira
where the traditional agricultural practices are still
keeping this Portuguese region free from corn
hybrids. The description of the Madeiran corn
landraces allows us to preserve the existing corn biodiversity and could be used for their registration as
conservation landraces or for conservation and
breeding proposes worldwide.
