Table 4.
Vegetative growth, yield components and vine balance recorded on vines of SG (susceptible clone R10) and accession 72-096 (resistant). PF = partially sprayed. FS = fully sprayed.

Cluster thickness is given as total fresh berry mass to rachis length ratio (g/cm). LA = leaf area
* and ** denote significant differences between treatments at P < 0.05 and 0.01 according to within column mean separation performed with SNK test and showed by small letters. ns = not significant.
