Conservation and sustainable utilization of plant genetic resource of the country is the broad vision of the Plant Genetic Resource Division of JNTBGRI and engaged with the specific mission to conserve diverse botanical entities from the Western Ghats, Northeast India and the Andaman – Nicobar Islands for the sustainable development of the State as well as the country. The Indian flora constitutes approximately 45,000 species including 17,000 vascular plants. Out of the officially recorded 120 botanic gardens in India, JNTBGRI is the one and only institution which maintains conservatory garden for wild tropical plant genetic resources of the country. PGR Division plays a key role in this regard by persevering live collections of various economically important plant groups, such as medicinal, aromatic, spice plants, orchids, bamboos, insectivores plants, endemic and endangered species from various regions of the country.
Presently Plant Genetic Resource Division holds living collections of about 1200 taxa of medicinal, aromatic and spice plants. The Bambusetum holding 69 species of bamboos/reeds procured from different regions of Indian subcontinent and Andaman-Nicobar Islands represents the largest bamboo collection in India. The living collections of wild orchids include several endemics and endangered elements from the Western Ghats, Eastern Ghats, Himalayan regions, Northeast India and the Andaman-Nicobar Islands is unique and enumerates 650 taxa. A unique live collection of Indo-Malesian insectivorous plant species is also well maintained by the PGR Division. The live insular accessions from the Andaman-Nicobar archipelago introduced in JNTBGRI is the largest ex-situ conservation (120 species) of the Andaman species among any botanic gardens in the world, which include medicinal plants, wild relatives of spices and other cultivars, wild edible fruit plants, insect repellant species, endemic and critically endangered taxa, economically viable timber and rattan yielding species best for social forestry and afforestation programmes along the slopes of the Western Ghats. One of the National Gene Banks for select medicinal and aromatic plants constituted by the Governmant of India is being maintained by the PGR Division with holdings of 298 accessions of 25 species. The Seed Bank in PGR Division encompasses an active collection of 986 tropical species and engaged with seed germination / storage studies on selected tropical species. A commercial tissue culture unit is also functioning in PGR Division where multiplication of commercially important ornamentals like orchids, anthuriums etc, banana varieties and other plants of interest are carried out. PGR Division also provides genuine propagules and other plant materials for advance research to other Divisions of JNTBGRI as well as other organizations/Universities etc. Seedlings / saplings of selected plants are being supplied to the public and NGO’s as a part of the popularization of economically potential plants.
