Understanding of the genetic variability and proper cultivar identification of date palm constitute indispensable steps towards the development of breeding strategies (Ahmed et al. 2011). Selection for clonal propagation has not always modified sexual fertility or mating systems of fruit trees. In the date palm, some cultivars have evolved parthenocarpy, but because the resulting fruits are smaller and develop more slowly than those of artificially pollinated plants, the cultural practices of laborious hand pollination have been conserved and practiced for millennia (McKey et al.
The percentage of heterozygous genotypes in a population). So far, only a small part of the total genetic diversity, including date palm, has been characterized, evaluated, and used for crop breeding and improvement purposes (Dhanapal 2012). Sexual expression in palms is spatially separated at five discrete levels; these are within flowers (in between floral organs), within flower clusters (in between flowers), within inflorescences (in between partial inflorescences), within palms (in between inflorescences), and in between palms.
Five-thousand-year-old date seeds have been found in Mohenjo Daro in the Indus river valley, and in 4,500 BP, the date palm was used in the construction of the temple of the Moon god in Ur of lower Mesopotamia. However, some authorities (Barrow 1998; Wrigley 1995; Zohary and Hopf 2000) suggest that the specific center of origin of Phoenix dactylifera within lower Mesopotamia is somewhat unclear, and a multidisciplinary approach, combining evidence from historical, cultural, archaeobotanical, and ecological sources, is needed to resolve this issue.
