Water chestnut (Trapa natans var. bispinosa Roxb.) locally known as singhara, is an important annual aquatic fruit crop belonging to the family Trapaceae. Since it is a potential crop for water logged areas cultivated on a large scale in Uttar Pradesh a preliminary survey, collection and evaluation of different cultivars of water chestnut for their physical and biochemical parameters was conducted by Babasaheb Bhimrao Ambedkar University, Lucknow from 2005-2008 in order to explore the possibility of genetic variability in water chestnut. The studies showed that considerable variation was found in the leaf length (4.33-6.60 cm), leaf breadth (4.10-7.86 cm), petiole length (5.96-10.46 cm), fruit pedicel length (3.70-5.20 cm), fruit length (3.11-4.89 cm), fruit breadth (3.38-6.38 cm), cheek diameter of fruit (3.26-4.41 cm), fruit weight (13.20-66.5 g), fruit volume (11.30-27.80 ml), specific gravity of fruit (1.01-1.37), kernel length (2.85-4.89 cm), kernel breadth (3.24-4.84 cm), cheek diameter of kernel (1.20-4.13 cm), kernel weight (7.0-17.50 g), kernel volume (4.80-13.68 ml), specific gravity of kernel (1.16-1.76), peel weight (4.74-21.57 g), thickness of peel (0.14-0.40 cm), kernel:peel ratio (0.91-4.73), TSS (4.33-10.55°B), ascorbic acid (5.05-9.70 mg/100 g) and acidity (0.07-0.10%).
