The Lakshadweep is a tiny landmass of 32 km2 area (8o–12oN, 71o–74oE) constituted by a group of 27 small atolls located in the Indian territory of Arabian Sea of Indian Ocean. Studies on crop genetic diversity including wild relatives of crop plants of the region are little known except for coconut palm. This report deals with 106 collections assembled in two exploration and collection missions comprising 46 plant species under 35 genera belonging to 24 families. The plant germplasm collected during the trips are mostly useful as vegetable, fibre, medicinal plant, dye, edible tuber, timber and ecosystem service provider. The crop wild relatives collected during the study include that of sunnhemp, melon, yam, jute, pigeon pea, sugarcane, etc. A set of germplasm accessions was sent to national research institutes for regeneration. Out of the total collection, 64 accessions were assigned with national identity (Indigenous Collection or IC numbers: IC 0572014 to IC 0572077), and conserved in long term storage at NationalGene Bank orin thefield gene bank ofICARNBPGR, New Delhi. The important germplasm assembled from the islands include highly pungent betel leaf and a large fruited noni. Plants of Cajanus scarabaeoides (L.) Thouars, bitter less Cucumis melo L. var. agrestis Naudin saline tolerant Canavalia cathartica Thouars, Vigna marina (Burm.) Merr. and Corchorus trilocularis L. were the unique wild relatives collected. The current report is the first of its kind on the exploration and collection of plant genetic resources (other than coconut) from Lakshadweep Islands. Wild melon accessions collected are currently employed in distant hybridization programs. During the survey, ethnobotanic information of 23 plants for medicinal and other uses was also documented. Novel uses of the native plant species in the islands indicate their potential for exploitation in other coastal ecosystems. This report aims to highlight the potential plant resources of the region for direct human use and in future breeding programs. Not Available |
