Abstract: To find out suitable cultivar of aonla (Emblica officinalis Gaertn) in laterite zone of West Bengal, a study was made on seven released varieties viz., Anand 1, BSR1, Chakaiya, Kanchan, Krishna, NA 10 and Neelum for six consecutive years adopting randomized block design. The soil was laterite and acidic in nature. Significant variation in yield and physicochemical characteristics of fruits of different cultivars was observed. The cultivar Neelum gave peak production of 80 kg plant-1 at 9 year of age with an average of 56.0 kg tree-1 followed by Kanchan which produced maximum yield of 60 kg tree-1 at 9 year of age with an average of 27.7 kg tree-1. These two cultivars were found to resistance and tolerant respectively against the stem borer pest. The highest fruit weight (35 g) with maximum in size (4.5×5.0 cm) was observed in Neelum while highest pulp content was noted from Kanchan (95.0%). The TSS content was maximum in Anand 1 and BSR 1 (14.2-14.3%) and minimum in Krishna (11.0%). The ascorbic acid content was highest in Krishna (475 mg 100-1 g) followed by Neelum (460 mg 100-1 g). Considering overall performance and presence of self-incompatibility phenomenon in aonla, the cultivars Neelum and Kanchan (10:1::Neelum:Kanchan) can be recommended for commercial cultivations in orchards under red and laterite zone of West Bengal..
