Controlled pollinations are widely used in fruit and forest treebreeding programs to combine desirable traits from selected geno-types and to perform different studies of reproductive biology suchas pollen limitation, self-incompatibility, length of the effective pol-lination period or pollen competition. In some particular cases,controlled hand pollination is a powerful tool to improve bothyield and fruit quality (Burd, 1994; Gonzalez et al., 1998; Loraet al., 2006).
