Vitis vinifera, AFLP, clones

Molecular tools are successfully applied in viticultural studies.

First of all, SSRs have had a great importance in characterisation in characterisation of different varieties and in the definition of phylogenetic relationships among V. vinifera.

Molecular fingerprinting is, actually, a great support for traditional ampelography; which based on phenotipic characterisations.

At the present time, if varietal characterisation is in progress and doesn’t seem to be a problem, the same approach seems not to be so easy for clone characterisation.

The clones of most important cultivars (Traminer, mn Pinot, Sangiovese, Chardonnay, etc.) are, actually, described and defined only following morfological traits.

AFLP technique was set up as a consequence of imposibility of a clear distinction using SSR analysis.

First data have shown polimorfisms, and the entity of genetic diversity among different clones.

Future investigations will permit us to transform these polimorfic bands in SCAR markers usables in clonal characterisation.
