Exploration expeditions were conducted for 2 consecutive years in the subtropical region of North India to collect the untapped genetic diversity of Bael. A total of 15 accessions having unique traits of horticultural importance were collected and conserved in the field gene bank. Conserved germplasm was characterized for 3 consecutive years. Considerable variability was found in the morphological characters and biochemical traits. Fruit length ranged from 10.15 to 17. 68 cm, fruit circumference varied from 33.45 to 56.32 cm and fruit weight varied from 0.71 to 2.48 kg. Shell thickness was found to vary from 2.11 to 3.62 mm, whereas shell weight varied from 230 to 580 g/fruit. Number of seed sacs per fruit was found to vary from 11.17 to 15.72 and number of seeds per fruit varied from 68.00 to 113.17. Minimum seed weight was 7.04 g/fruit, whereas maximum 14.55 g/fruit. Ample variability was found in fruit yield of collected germplasm which ranged from 18.85 to 39.26 kg per plant at 16–18 years of age. Distinctive variability in biochemical traits was also found. Total soluble solids in fruit pulp were 34.92–41.13% Brix, total sugars 11.49–22.16%, acidity 0.36–0.53%, vitamin ‘C’ 9.89–17.20 mg/100 g, total carotenoids 1.43–2.40 mg/100 g and total tannins 2.50–3.58%. Available genetic diversity may be utilized for crop improvement programme.
