Amongii these data records associated with herbarium specimens’ label have now become available for large scale innovative research at the global level. Despite realizing the value of herbarium decades ago only in the past few years the knowledge hidden with the herbarium repositories the potential resources for new findings have been explored now using e-resources and vast floristic literature. Various global database facilities such as the Global Biodiversity Information Facility (GBIF), the Atlas of Living Australia (ALA), the US Geological Survey’s portal (Biodiversity Information Serving Our Nation; BISON), and iDigBio (Integrated Digitized Biocollections) provide digital biodiversity data, including information from herbarium specimens. Digitized herbarium specimen data serve as resources for synthetic analyses, link the phylogenetic, climatological and genomic resources to address several unresolved queries in plant sciences. Researchers in plant systematics are now benefitted with the enhanced understanding of diversity distribution, plant collecting strategies, seed storage behaviour, and taxonomic identification. Value of herbarium as a powerful tool in plant genetic resources programme was realised as early as 1948 when a build-up of herbarium voucher specimens generated through research activity was maintained as referral collection in the Botany Department of IARI (which later named as the Plant Introduction Division, IARI, Pusa). Later, the institute was rechristianization as ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR) in 1976 and since then it has been instrumental in disseminating knowledge on use of herbarium through teaching and training programmes, formal and informal technical discussions, brainstorming sessions and know-how on herbarium methodology. In continuation to these efforts, the ICAR-NBPGR is now organizing a short training course on “Herbarium Management” for participants from Directorate of Seed Testing and Certification, Ministry of Agriculture, Baghdad, Iraq with financial support from Government of Iraq from July15-20, 2019. For the benefit of participants a training manual entitled “Herbarium Management: Methods and Current Trends” is published with an overall perspective on the management of the herbaria. A total of eleven chapters including practical exercises and demonstrations will contribute towards a better understanding of herbarium management. Use of taxonomic keys in plant identification, herbarium and field methods, and biosystematics tools in species delimitation will help in build- up of the herbarium, besides enhancing their expertise. Topics like advances in modern tools, illustrative guides and herbarium digitization will help to boost the confidence of participants in setting up of state-of-the-art facility with their organisation(s). This training would sensitize the participants to create effective interest in the management of herbarium. We are highly thankful to the authors for contributing the contents of various chapters and bringing their views in this form. We hope that this publication will serve as a valuable reference to the course trainees as well as other users associated with PGR sciences. (Anjula Pandey) i Herbarium Management- Role in Plant Genetic Resources Study (Anjula Pandey) 1 Herbarium Management- Role in Plant Genetic Resources Study Anjula Pandey Division of Plant Exploration and Germplasm Collection ICAR-National Bureau of Plant Genetic Resources New Delhi 110 012, India Introduction There are approximately 4,000 recognized active global herbaria collectively holding 35,00,00,000 herbarium specimens. India represents over 3.5 million herbarium specimens including~23,000 type specimens (source:http://sciweb.nybg.org/science2/IndexHerbariorum.asp). These major global herbaria are committed to providing herbarium of economic species accessible to users (K, P, MO, S, B, UC/JEPS), and yet some others focus on regional flora (F,BM, PE, E, CAL). Among the cultivated plant herbaria, only a few of them are rich in the representation of cultivated plants (H- cultivated ornamentals and The Gatersleben Herbarium (GAT- Crop Plant Genetics mainly). GAT is located in the Department of Genebank of the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) and is one of the largest specialized herbaria which serve as a source of reference and working material for the reproduction of accessions maintained in the genebank and other institutional research programmes. The holdings include over 0.430 million specimens of cultivated plants and its wild relatives, seed and fruit collection (about 0.1 million samples) and the spike collection (55,000 samples) (http://www.ipk-gatersleben.de/en/gbisipk- gaterslebendegbis-i/herbarium/).List of selected herbaria with significant information is given in Appendix I. Management of a herbarium includes all the activities pertaining to build-up, maintenance and research undertaken to establish a facility. While developing a herbarium state-of-the-art facility, the activity begins with the build-up of the collection followed by all other activities. A herbarium is a repository of plant specimens to serve as valuable resources for plant and data used for scientific research. For a quality specimen, an ideally dried herbarium should have character representation (vegetative characters: roots, tubers, bulbs and rhizome, leaf, stipule, spine, bark, etc. and floral: inflorescence, flower- spathe, scape, stamen, sepal, petal/tepals; and fruit characters: pericarp, 1 Herbarium Management- Role in Plant Genetic Resources Study (Anjula Pandey) placentation, seed) needed for taxonomic studies (Lawrence 1951; Davis and Heywood 1963; Holmgren and Holmgren 1998). Information on plant species with respect to the area of availability, variability pattern, flowering/fruiting time, status on rare/endangered/endemism, other ecological features, economic uses, indigenous traditional knowledge (ITKs), etc. gathered from herbarium label data serves as resource for basic and applied research, referral use and for educational programme. The information available on the herbarium label could be helpful in the planning and management of genetic resources and may serve the users in various ways. ‘Voucher specimens’ used in experimental studies as well as those collected from diverse areas and deposited in herbaria can be used for further study by others. Herbaria located in teaching/ educational institutions will have specimens generated through basic study and applied sciences. On the other hand, institutions dealing with
