A contribution to the characterisation by electrophoresis of grape plant varieties cultivated in Galicia (NW Spain)

Abstract

Electrophoresis was employed as the method of study for the characterisation of Vitis vinifera varieties cultivated in Galicia (Spain). Mature dormant shoots were used for the study. The enzymatic system glucose- phosphate isomerase (GPI) was analysed using the method of PARFITT and ARULSEKAR (1989). Seventeen varieties (Albariño, Dona Blanca, Godello, Loureira, Treixadura, Torrontés, Albillo, Palomino, Verdejo Blanco, Macabeo, Jerez Fina, Asal Galego, Moscatel Galego, Galego Dourado, Galego de Montemor, Brancellao, and Caiño Bravo) were studied. Eight groups of phenotypes were obtained. Each one of which had clearly differentiated characteristics from more than one varity, except in the case of Garnacha.
