The first clonal selection works in Italy were carried out by Breviglieri in 1943, when he noticed an intravarietal variability in the varieties cultivated in Tuscany. Since then, the study of clones has stimulated research for new genetic materials characterized by high performance. The Council Directive 68/193/EEC of 9 April 1968 (concerning the marketing of material for vegetative propagationof vines) and subsequently the Presidential Decree of 24 December 1969 (n.1164) entitled “production and marketing of vine pre-multiplication material” gave a positive impulse to promote clonal selection activity. These decrees forced a gradual change from standard (of massal origin) to certified material (obtained through clonal selection activity). The Institutes of Pomology of the Universities of Florence and Pisa, during the period 1960-1975, promoted research to establish and reorganize Tuscany’s ampelographic platform. These studies focused on identifying suitable varieties for cultivation in different Tuscan provinces.
Bandinelli et al. (Mon,) studied this question.
