Abstract

discriminant analysis of phyllometric parameters was used to study the differences in leaf morphology observed between virus-infected and heat-treated healthy progenies of four clones of the Nebbiolo cultivar.
Viral agents investigated were grapevine fanleaf virus (GFLV), grapevine fleck virus (GFkV) and a mixed infection of grapevine virus A (GVA), a vitivirus involved in the aetiology of Kober stem grooving.
Grapevine leafroll-associated closteroviruses 1 and 3 (GLRaV-1 and GLRaV-3) were investigated too.
The results confirm the importance of genotype in determining leaf morphology despite the presence of viral infections.
However, being the effect of the investigated viruses not negligible (in particular of GFLV), a clone may be correctly identified by its leaf morphology only when free from the major viruses.
