Resumo(s)
This paper presents the first comprehensive morphological characterization and identification
of the wheat populations collected on the Archipelago of Madeira and preserved at the ISOPlexis
Germplasm Bank, the University of Madeira, Funchal. Fifty-two wheat populations representing
Madeira’s Triticum diversity and a wide range of
ecological conditions were evaluated based on the
biometrical and cytometrical traits. Forty-six traits
related to plant morphology, cytological and grain
characteristics were included in a multivariate analysis. Taxonomic identification of the collected
materials revealed the presence of 3 species, 2
subspecies and 16 botanical varieties among the
Madeiran wheat germplasm. The obtained results
were confirmed by the multivariate analysis since all
accessions were grouped in clusters corresponding
also to different taxonomic levels. The detailed description of the Madeiran wheat landraces may
contribute also to the protection of the existing
Triticum diversity as well as support efforts of
conservation of landraces, proper germplasm preservation and utilization.
