The technique is as rapid as commercial kits and requires only small amounts of material. As it does not require RNase treatment, its application is approximately one-eighth of the cost. The possibility of applying the same DNA extraction method to different tissues is advantageous for two reasons: it diminishes a source of heterogeneity and it can be applied to samples obtained during any season of the year, including winter. The proposed method provides high-quality DNA with a good yield from the leaves, seeds, and stems of V. vinifera and guarantees identical results of posterior SSR analyses, regardless of the tissue used and the stage of ripening at which it was collected. Furthermore, since it can be applied to stems, this method can be used as a first step of quality control in grapevine nurseries. ER -
