Fully and Partially Replicated Experimental Designs for Evaluating Intravarietal Variability in Grapevine

Table 1

Description of the fully replicated design (resolvable row-column design, RCD) adopted for the field trials of six grapevine varieties and the partially replicated design (PRD) adopted for the field trial of Bastardo variety.
