Abstract

The research work was carried out to determine the physico-chemical characteristics of 10 selected drumstick germplasm available in the south-western region of Bangladesh during August, 2012 to January, 2013. The experiment was laid out in Completely Randomized Design (CRD) with three replications. There was found a significant variation among the germplasm in relation to leaf, flower and pod. Better results were obtained from germplasm No. 01, 06, 09 and 04, in respect of total weight of leaf, length of leaf, weight of pod, skin thickness of pod, edible and non-edible portion of drumstick leaf, pod among the 10 selected germplasm. The highest leaflet number (597.333) was observed in germplasm No. 3. The highest weight of edible portion (10.347g) was observed in germplasm No.1, the highest percentage of edible portion was observed in germplasm No.9 (70.100%) and germplasm No. 4 gave the highest young pod weight (12.66 g), the highest weight of edible portion (9.290g) was observed in germplasm No. 4 in young pod, the highest percentage of edible portion was recorded in germplasm No. 5.In mature condition germplasm No.1 gave the highest weight (31.400g) of mature pod, germplasm No. 2 gave the highest pod length (48.00 cm), the highest weight of edible portion (30.72g) was observed in germplasm No. 1, the highest percentage of edible portion was observed in germplasm No. 4 (90.73 %).It was observed in the data of chemical analysis of leaf that the highest vitamin C content of leaf (101.7 mg /100 g) and titratable acid content (21.33%) was recorded from germplasm No. 4. The highest percentage of TSS (1.667 %) was observed in germplasmNo. 1, anthocyanin (0.140 mg /100 g) was observed in germplasm No. 10. In respect of flower, the highest percentage of TSS recorded from germplasm No. 5 (10.00 %), the highest amount of carotenoids content (0.01163 mg /100 g) was observed in germplasm No. 2 and flavonoids content (0.0870 g /100g) recorded from germplasm No. 6. In respect of young pod the highest pH was found in germplasm No. 5 (6.486), the highest vitamin C content (80.00 mg /100 g) and carotenoids content (0.003 mg /100 g) was observed in germplasm No. 2. In mature condition the highest amount of carotenoids content of mature pod (0.4267 mg /100g), the highest vitamin C content (80.00 mg /100 g) and flavonoids content of mature pod (0.09605 g / 100g) was recorded from germplasm No. 1.
