The performance of 24 ber (Z. mauritiana) in terms of growth, yield and yield components were studied under the tarai conditions of Uttaranchal, India during 1998-99. Sanaur 6 recorded the highest tree height (5.75 cm) and spread (11.90 m), trunk girth (2.13 m), cross trunk sectional area (3616.08 cm2) and volume (1698.39 m3). Rohtak Gola, Seo, Nazuk, Narikeli and Sanaur 2 recorded the highest shoot length (248 cm), number of leaves per shoot (515.50), leaf length (10.68 cm), length:breadth ratio (2.32) and photosynthetic efficiency (0.182 mg/cm2/h), respectively. Sanaur 3 recorded the highest leaf breadth (7.71 cm) and area (43.19 cm2); ZG3 recorded the highest number of fruits per shoot (50.50) and per tree (11665.50), and yield (214.40 kg); and ZG 2 recorded the highest yield efficiency by weight (0.215 kg/cm2) and number of fruits per m3 volume of tree (59.05).
