  • Longan (Dimocarpus longan Lour.), an important subtropical fruit in the family Sapindaceae, is grown in more than 10 countries. Longan is an edible drupe fruit and a source of traditional medicine with polyphenol-rich traits. Tree size, alternate bearing, and witches' broom disease still pose serious problems.
  • It is originated from South China or Southeast Asia and is commonly called longan or “dragon eye” in Asia. It is an important tropical/subtropical evergreen fruit tree that has a diploid genome (2n = 2x = 30) and belongs to the family Sapindaceae. Longan is widely cultivated in Southeast Asia, South Asia, Australia, and Hawaii.
  • China's longan acreage and production rank first, accounting for 70% and more than 50% of the world's acreage and production, respectively[1] [2] .
