Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. Jack fruit has diverse medicinal uses especially as anti-oxidant, anti-inflammatory, antimicrobial, anti-cancer and anti-fungal agent. Jackfruit is considered to be an underutilized fruit where most of the fruits get wasted due to ignorance, lack of post-harvest technology and gaps in supply chain systems. Jackfruit contains more protein, calcium, iron, vitamins and other essential nutrients, compared to common fruits. To find out the morphological variations among jackfruits in Kerala we conducted an elaborate survey and found out varieties using parameters such as tree characteristics, leaf characterises, fruit characteristics of selected samples as measure. Both qualitative and quantitative data were measured using field visit and standard methods and morphological indicators. After analysis of data morphological variations among the jack fruit samples were identified. This includes the morphological difference between fruit stalk leaf and branch leaves. In the fruits themselves, colour, shape and size are also found to vary among the samples. These variations may have some relationship to climatic factors such as rainfall, pH and soil properties. Morphological variations affect the selection of the varieties. Encouragement should be given to the marketing as well as creation of value added products from this underutilized fruit tree.
