Distinguishing
Characteristics of Fruits
12
Fruit Domestication Factors
  • Recognition of species
  • Selection of elite genotypes
  • Vegetative propagation technology
  • Cultivation technology
    • Pruning and training, irrigation, pollination, pest control
  • Utilization
    • Storage, drying, fermentation, processing
13
Fruit Domestication
  • Interaction of cultural technology and genetic change
  • Vegetative propagation essential
  • Dispersal of fruit crops with human migration
  • Most fruit crops are closer to wild species than annual crops such as grains

Laws of Hammurabi, ca. 1750 BCE
  • §64. If a man give his orchard to a gardener to pollinate (the date palms), as long as the gardener is in possession of the orchard, he shall give to the owner of the orchard two thirds of the yield of the orchard, and he himself shall take one third.
  • §65 If the gardener does not pollinate the (date palms in the) orchard and thus diminishes the yield, the gardener (shall measure and deliver) a yield of the orchard to (the owner of the orchard in accordance with) his neighbor’s yield.

Conclusions
  • Our fruits are legacies of Neolithic and Bronze Age farmers
  • Persistence of farmer-selected cultivars due to unique quality factors making them difficult to replace
  • Deficiencies made up by cultural techniques and genetic changes
  • Knowledge of domestication makes it possible to predict future changes:
    • Search for specific mutations (parthenocarpy and seedlessness, breakdown of dioecy, loss of compatibility, high sugar, loss of astringency)
    • Use of interspecific crosses to create new fruits (Citrus, Prunus, Rubus)
    • Selection of underexploited germplasm (pitaya)
