Dataset of agromorphological traits in early population of turmeric (Curcuma longa L.) local accessions from Indonesia.

Turmeric (Curcuma longa L.) is widely used as traditional medicine, kitchen spice, and natural dyes in Indonesia. The demand and popularity of this plant is increasing; however, the national supply is still low. Turmeric breeding and crop improvement in Indonesia are needed to boost the national turmeric production. Exploration of turmeric from various areas in Indonesia is a prior step of turmeric breeding. Phenotypic diversity and relationship analysis of an early population can be used as a basis for consideration in plant development and breeding programs. The purpose of this study was to estimate phenotypic diversity and relationship of local turmeric accessions from Indonesia. Raw data analysis was conducted after standardization using Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA) to determine phenotypic diversity and relationship among the newly collected genetic resources. The data in this article showed broad phenotypic diversity with plant height, number of shoots, number of leaves on main shoot, petiole length, lamina length, lamina width, number of mother rhizome, total rhizome weight, weight per shoot, pseudostem habit, leaf margin, and rhizome habit as distinguishing traits among the collection. PCA also resulted cumulative variation percentage of 70.73%. In addition, HCA resulted two main groups with the Euclidean range of 0.31-2.97.

Ethnobotanical dataset on local edible fruits in North Sulawesi, Indonesia.

This dataset describes the knowledge of local people in North Sulawesi on local edible fruits which can be eaten raw or used as medicine. North Sulawesi is located in the Wallacea zone [1,2] and has a high biodiversity of local fruits that are not yet fully exploited. Fruits are available as rich sources of vitamins, fibres, minerals, and phytochemicals [3] for local people's diet and health. Ethnobotany was used to collect data for the documentation of local knowledge on the existence, the use, and conservation practices of local fruits using semi-structured and structured interviews and questionnaire. There were 27 recorded families of local edible fruits, predominated by Myrtaceae and Anacardiaceae. Some fruits were found abundantly, but some were rarely found, especially those which were endemic to North Sulawesi. The fruit trees were mostly self-grown, and the fruits were eaten by the community themselves. In general, they were well aware of the types of local fruits that could be eaten raw. Knowledge of local fruits were passed on from generation to generation. Most people claimed that local fruits which could be eaten raw were also used for medicine and maintaining health. Most of the local fruits used as medicines were not made as medicinal preparations, but eaten raw or cooked. However, most people did not know exactly about the efficacy of the fruits. Types of diseases that were claimed to be cured by using local fruit among others were sprue, high cholesterol and digestive disorders. The possibility of future youth generations to consume these fruits was very high, according to most people. But they were worried that the younger generation in the future would prefer imported fruits. The community in general knew that these local fruits needed to be conserved, but they did not yet know how to maintain the existence of these local fruits in the future, apart from their current practices.
