Abstract
Mucuna Adans., commonly known as the velvet bean, has a great potential not only being a genus of medicinal importance in the Indian system of medicine as a source of L-dopa but also as food, livestock feed, cover crop and being tolerant to abiotic stresses. Exploration and germplasm collections were undertaken in different phyto-geographical zones and tribal dominated areas of Odisha in Eastern India to study the species diversity, extent of genetic variability and associated indigenous traditional wisdom. Forty-one germplasm accessions representing five taxa viz. Mucuna monosperma (2), Mucuna nigricans (2), Mucuna gigantea (1), Mucuna pruriens var. pruriens (34) and Mucuna pruriens var. utilis (2) were collected from the state which exhibits a wide range of inter- and intra-specific variability in pod and seed morphology and L-dopa content in seeds, and further conserved in the National Gene Bank, New Delhi. An identification key, significant botanical characters and the systematic treatment for each taxon was provided for easy identification. The promising genotypes having high L-dopa content and the significant agro-morphological traits pertaining to pod and seed were identified for large scale cultivation and they serve as potential source for crop improvement and breeding programmes. The information on indigenous traditional knowledge collected from major tribal communities of Odisha revealed the immense importance of Mucuna for food and healthcare needs, thus some significant ethno-medicinal uses including their mode of administration were presented.
