Abstract(s)
The variability of fifty populations of
common bean (Phaseolus vulgaris L.), representing a
wide range of ecological conditions on the Island of
Madeira, was evaluated based on morphological and
reproductive traits. Individual data of 58 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
common varieties were clustered into fifteen groups by
their degree of dissimilarity, based on discriminant
analysis. The dissimilarity of these groups was con-
firmed by one way ANOVA. The racial rank of these
groups was proposed and a brief description of the
common bean landraces was presented. This work
represents the first morphological characterization and
analysis of diversity of bean germplasm from the
Archipelago of Madeira, where the traditional agricultural
practices are still keeping this Portuguese region
free from improved bean varieties. The description of
the Madeiran bean landraces allows the preservation of the existing bean biodiversity and could be used for
their registration as conservation landraces, or for
conservation and breeding purposes worldwide.
