Average genetic similarity between pairs of plants was 0.61 ± 0.02, with a range of 0.46-0.87. The highest similarities were obtained among European varieties. Fiana and Armada recorded 0.87, Alfa Grande and Armada, 0.83, Alfa Grande and Fian,a 0.81 and Cambray Blanca DF and Mochis 0.81. The lowest similarities were recorded between LB5-5 and Tollocan (0.46) followed by Cambray Rosa Morelos (0.48), and Gigant and Tollocan (0.48). Tollocan was the most divergent at a similarity coefficient of (0.53) from the rest of the accessions (Figure 2A).
