Physico-Chemical Characteristics of Tomato (Lycopersicon esculentum Mill.) Germplasm Available in South Western Region of Bangladesh

Abstract

The research work was carried out to determine the physico-chemical characteristics of 13 selected tomato germplasm collected from the south-western region of Bangladesh during December 2012 to May 2013. The experiment was laid out in a Completely Randomized Design (CRD) with three replications. A significant variation among the germplasm in relation to fruit characteristics was observed. The highest values were found in germplasm No. 6 in respect of total weight of fruit, length of fruit, width of fruit and depth of fruit among the 13 selected germplasm. The highest seed weight of fruits was observed in germplasm No. 2. The highest titratable acidity (0.953%) was observed in germplasm No. 12. The highest vitamin C (24.33 mg/100 g) content of fruit pulp was determined from germplasm No. 3, while germplasm No. 13 was best in respect of pH (4.833), germplasm No. 3 in total soluble solids (6.033%) content, germplasm No. 5 in carotenoids (0.848 mg/100 g) content, germplasm No. 2 in anthocyanin (0.125 mg/100 g) content and germplasm No. 11 in flavonoids (5.270 g/100 g) content of fruit pulp. The highest antioxidant was found in germplasm No. 7 and that was lowest in germplasm No. 9.
