Abstract:
An investigation on morphological and Physico-chemical characters of 10 elite jamun genotypes was undertaken at Department of Fruit Science, Horticultural College and Research Institute, Periyakulam. Ten jamun genotypes viz., SC-01 to SC -10 showed wide range of variation with respect to morphology, plant growth, flowering and yield traits of fruit. Among 10 genotypes observed, two were found to be of early bearer, six mid and two were of late bearing habit. Genotype SC-04 recorded significantly higher fruit weight (17.05 g), fruit length (3.95 cm), fruit breadth (2.43 cm), pulp weight (14.71 g), pulp per cent (86.28%) and pulp to seed ratio (6.29). High TSS was recorded in SC-04 (16.50 °Brix) while lowest in SC-09 (7.62 °Brix). Significant differences were observed for total, reducing and non-reducing sugar content among the genotypes. Lowest acidity was recorded in SC-04 (0.59%) and highest in SC-09 (1.06%). Highest TSS: acid ratio was recorded in SC-04 (27.97). Comparative results of ten jamun germplasm evaluation, the result showed that SC-04 genotype was better in terms of morphology of fruit, fruit yield and other physicochemical characters.
