Differenciation of clones of varieties of grapevines that are traditionally cultivated in NW Spain (Galicia) and elaboration of determination key for application of philometric measures

Abstract

Application of philometric methods in the differentiation between clones of the varieties of grapevines that are traditionally cultivated in Galicia (NW Spain) has been studied. Our aims is to work whith a number of leafparameters as large as possible to ensure differences among clones.

Experimental measurements have been obtained using Computer Techniques (ROMANI et al., 1993). They have been analyzed by commercial statistic package using of Discrimination Analysis (SAS Statistical Programme). We have to establish separation at clone level for each variety, by means of using certain discrimination parameters which allow us to elaborate determination keys. The parameters which best explain the differences between the clones would be the shape and size of the dentation, leaf bosoms and the whole leaf in general
