Abstract

The investigation entitled “studies on survey, collection and evaluation ofwater chestnut (Trapa natans var. bispinosa Roxb.) under Sathiaon Block of AzamgarhDistrict of Uttar Pradesh” was carried out comprising eight villages viz., PahiGhat, Mafiya, Pichari, Rasulpur, Amilo, Baniyapara, Hafizpur, Ojhauli in theAzamgarh district of U.P. in 2007-08. The Physico-chemical parameters wereobserved in the Laboratory of the Department of Applied Plant Science(Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow. Fifteencultivars 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 thesevillages. It has been observed that maximum length of fruit and cheek diameterwas 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 cultivarHara-2 (4.716 cm, 37.796 g. and 3.916 cm, respectively). Maximum peel weight wasrecorded in cultivar Hardiya-1 (23.836 g). Maximum weight, length of kernel andcheek diameter was recorded in cultivar Dambu-1 (14.500 g, 3.838 cm. and 3.863cm, respectively). Maximum T.S.S. content was recorded in cultivar Hardiya-2(10.533 0Brix). Maximum ascorbic acid and acidity content was recorded in cultivarKhas Gulab-2 (9.703mg/100g and 0.0910 %, respectively), while the minimum aciditywas recorded in cultivar Bhundiya-1 (0.0640 %).
