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

Background and Aims. In ancient grapevine varieties, the experimental design of field trials is crucial to providing a reliable evaluation quantitative traits. The main purposes this study are demonstrate benefits resolvable row-column (RCD) for quantifying intravarietal variability performing polyclonal selection compare efficiency fully partially replicated designs implement latter preliminary analysis that variability. Methods Results. Linear mixed models were fitted yield data obtained in with designs. results pointed out importance RCD controlling spatial present large trials. Although less precise, proved be useful evaluating when average years was used. Conclusions. reinforced increasing quantification selection. only objective perform Significance Study. Understanding role will help breeders enhance their knowledge about within varieties more successful
