formation of unreduced gametes (pollen and/or eggs). When an unreduced gamete unites with another unreduced gamete (bilateral) or with a normal haploid gamete (unilateral), the union leads to sexual polyploidization. To a certain extent, polyploidization via

was uncertain ( Etoh and Simon, 2002 ). However, within the last 15 years, true seed production via sexual reproduction in garlic has been demonstrated, and it is now thought that variation created by genetic recombination is the basis for differences

, and because the importance of sexual reproduction was demonstrated for grape ( Bowers et al., 1999a ), we suppose that ‘Sangiovese’ originated from spontaneous or voluntarily crossing, likely in southern Italy, and was transferred as a seed, like

, 2004 ). P. capsici has high genetic diversity in the field because this pathogen is polycyclic and can undergo both sexual reproduction, with different mating types, and asexual reproduction ( Erwin and Ribeiro, 1996 ; Walker and Bosland, 1999
