1. Introduction
Washington oranges, also known as “Washington Navel Oranges,” are among the most well-known and popular oranges worldwide. Originally from Brazil, they were further cultivated in the United States and have become synonymous with high-quality citrus fruits.
2. Origin and History
The first Washington Navel oranges were brought from Brazil to California in the mid-19th century. In 1870, the U.S. Department of Agriculture received a shipment of orange tree seedlings from Bahia, Brazil. These were cultivated in Washington, D.C., and California, with the plantations in Riverside, California, achieving the greatest success. This is where the name “Washington Navel Orange” originates.
Washington oranges eventually made their way to Turkey. The first cultivation attempts began in the 1940s, particularly in the Adana region, which is known for its favorable climate and fertile soil. Today, Washington oranges are among the most widely grown orange varieties in Turkey and play a significant role in exports.
