West Bengal is a natural reservoir of less known fruit plants. These indigenous fruit species ensure security to the people for balance food and nutrition, development of marginal lands and protection against the disaster of ecological degradation. Some of these crops have huge medicinal properties. At present, human population is dependent on major fruit crops like banana, mango, citrus, guava, papaya, litchi, pineapple etc. and few minor fruit crops like custard apple, pomegranate, ber, aonla, sapota, jackfruit etc. The price of these fruit crops are beyond the reach of poor people as a result they suffer from malnutrition.

Considering these, the wealth of less-known fruits of West Bengal is discussed with their importance.
