The article highlights the significant growth of citrus cultivation in Turkey, originating from the planting of 150 saplings in Antalya in 1938. Over the past 83 years, the tree count has grown to over 40 million, with an annual production of 5 million tons, making Turkey a leading exporter of fresh fruits and vegetables. The Western Mediterranean Agricultural Research Institute (BATEM) has played a crucial role in breeding and cultivating various citrus varieties, currently preserving 934 citrus genetic resources. The institute also emphasizes the production of value-added products like jams, marmalades, and essential oils, underscoring the economic potential and the importance of citrus production in combating vitamin D deficiencies during the harvest season, which lasts from September to May across various provinces in Turkey.
