"Biological diversity" means the variability
among living organisms from all sources
including, inter alia, terrestrial, marine and
other aquatic ecosystems and the ecological
complexes of which they are part; this
includes diversity within species, between
species and of ecosystems.

Watermelon originated in
southern Africa
Spanish settlers were growing watermelons in Florida in 1576. Minimal breeding until 1954
by USDA in SC. Dr. Crall, UF/IFAS, developed “Jubilee” variety in 1963. Seedless watermelons
are sterile hybrids that develop fruits, but no seeds. The seeds for growing them are
produced by crossing a normal watermelon with one that has been changed genetically by
treatment with a chemical called colchicine. The seeds from this cross will produce plants
that, when pollinated with pollen from normal plants, produce seedless melons.
