Seedless barberry [Berberis vulgaris (L.) var. asperma] is member of family Berberidaceae.
It has been widely used as a food additive.
In Iran more than 5,000 tonnes of barberries are produced each year. Khorasan, located at the northeastern Iran, is the production center with about 6,000 hectares of field growing barberry.
Each year, more than 4,500 tonnes are harvested in Khorasan region alone.
Barberry cultivation in Khorasan is concentrated in the south of the province, especially around Birjand and Ghayen where environmental condition (i.e. hot weather, low relative humidity, water shortage and soil condition) are unfavorable for the growing of other horticultural crops.
Mean yearly precipitation is 190.3 and 173.5 mm in Ghayen and Birjand, respectively.
Minimum and maximum temperature are -38, +41 °C in Ghayen and -15, +44 °C in Birjand.
About 85% of production is in Ghayen and about 15% in Birjand. According to evidence the cultivation of seedless barberry in south of province backs to two hundred years ago.
The paper summarized detailed information about cultivation, taxonomy, propagation, utilization, and processing of seedless barberry cultivated in the southern parts of Khorasan, Iran.
