Abstract

The investigation entitled “studies on survey, collection and evaluation of water chestnut (Trapa natans var. bispinosa Roxb.) under Sathiaon Block of Azamgarh District of Uttar Pradesh” was carried out comprising eight villages viz., Pahi Ghat, Mafiya, Pichari, Rasulpur, Amilo, Baniyapara, Hafizpur, Ojhauli in the Azamgarh district of U.P. in 2007-08. The Physico-chemical parameters were
observed in the Laboratory of the Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow. Fifteen cultivars Khas Gulab-1, Chhota Dana, Light green (Safed)-1, Hara-1, Khas Gulab- 2, Hardiya-1, Hara-2, Light Green (Safed)-2, Khas Gulab-3, Dambu-1, Hara-3, Bhudiya-1, Hardiya-2, Dambu-2, Khas Gulab-4 were found to grow under these villages. It has been observed that maximum length of fruit and cheek diameter was recorded in cultivar Khas Gulab-1 (4.810 cm and 4.646 cm, respectively). Maximum fruit breadth, weight and breadth of Kernel was recorded in cultivar Hara-2 (4.716 cm, 37.796 g. and 3.916 cm, respectively). Maximum peel weight was recorded in cultivar Hardiya-1 (23.836 g). Maximum weight, length of kernel and cheek diameter was recorded in cultivar Dambu-1 (14.500 g, 3.838 cm. and 3.863 cm, respectively). Maximum T.S.S. content was recorded in cultivar Hardiya-2 (10.533 0Brix). Maximum ascorbic acid and acidity content was recorded in cultiva Khas Gulab-2 (9.703mg/100g and 0.0910 %, respectively), while the minimum acidity was recorded in cultivar Bhundiya-1 (0.0640 %).
