Abstract
Apple (Malus × domestica Borkh.) is one of the most widespread and
commercially important horticultural crops in the world.
Nowadays, there is an
increasing interest in autochthonous apple cultivars for organic farming as measure of
environmental sustainable practice, once they are a privileged material that by natural
selection acquired resistance to diseases and pests.
Moreover, many of the regional
cultivars have particular interesting organoleptic characteristics.
This work constitutes
the first molecular approach using ISSR markers on regional apple material from
Northwest Portugal.
A set of fourteen accessions representing autochthonous apple
germplasm was studied using nine ISSR primers in order to estimate their genetic
diversity and relationships.
The obtained data enabled to assess the high genetic
variability of the restricted number of Portuguese autochthonous apple material
analysed, to uncover possible synonyms and intracultivar variability and the detection
of possible identification errors.
