Watermelon

Watermelons are believed to have originated in northeastern Africa, possibly Egypt or Sudan, over 5,000 years ago. Ancient Egyptians cultivated watermelons, and seeds have been found in tombs, including King Tutankhamun’s.

From Africa, the watermelon spread to the Mediterranean, India, and China, eventually arriving in the Americas with European explorers. The seeded watermelon is the original form of the fruit and remained dominant in agriculture until the development of seedless hybrids in the 20th century.

Today, seeded watermelons are still grown commercially and for home gardens, particularly for those who value heirloom varieties, stronger flavor, or better storage performance.

Seedless watermelons were first developed in Japan in 1939 by breeder Kihara Hitoshi, using a process that crosses a tetraploid (4 sets of chromosomes) with a diploid (2 sets) watermelon to create a triploid (3 sets) fruit—sterile and unable to produce mature seeds.

Commercial popularity surged in the 1990s and 2000s, especially in the U.S., Mexico, and southern Europe, as consumers sought convenient, no-mess fruit options. Today, seedless varieties dominate supermarket watermelon offerings.

Mini watermelons are modern cultivars, developed through selective breeding—not genetic modification—to meet demand for convenient, single-serving fruits. First popularized in the early 2000s, they quickly became a staple in grocery stores across North America, Japan, and Europe.

They are available in both seeded and seedless varieties, and due to their smaller size, they tend to ripen faster, store better in refrigerators, and reduce waste—making them ideal for urban households, couples, or small families.
