CSFRC was established in 1930 as Falahat garden. It renamed to Ramsar agriculture station in 1960 and changed to a citrus station of west of Mazandaran in 1986. Therefore, this center had worked directly under supervision of seed and plant improvement institute (to 1992) and an independent citrus research center (1992-1994). In 1997 this center began to work as Iran Citrus Research Institute. Finally, according to subtropical climate condition, in March 2016, it renamed to Citrus & Subtropical Fruits Research Center (CSFRC) and now it is governed by Horticultural Science Research Institute.
