Conservation of grassland plant genetic resources through people participation D. R. Malaviya, A. K. Roy and P. Kaushal ABSTRACT Agrobiodiversity provides the foundation of all food and feed production. Hence, need of the time is to collect, evaluate and utilize the biodiversity globally available. Indian sub-continent is one of the world’s mega centers of crop origins. India possesses 166 species of agri-horticultural crops and 324 species of wild relatives. India is reported to have five grass covers identified. There have been almost nil human interference in terms of selection pressure; hence, the biodiversity is well conserved in these grazing lands. There is need of a system approach to understanding biodiversity that moves significantly beyond taxonomy and species observations. In addition to forage value, many grasses hold the medicinal value. Duplication in the collected germplasm is a serious issue. Hence, molecular tools need to be employed. Indian Grassland and Fodder Research Institute, Jhansi is maintaining >8500 germplasm of many fodder crops. For thousands of years farmers have been domesticating plant species thereby developing a wide range of crop varieties adapted to specific needs and environmental conditions and their rights have been protected through Indian Plant Variety Protection and Farmer’s Right Act. The use of diverse species and varieties by farmers enhances their adaptability and resilience capacity to changing environmental and economic conditions. Farmers in Manipur are conserving the biodiversity of the state by farming around 100 traditional varieties of paddy and rare medicinal plants. Old grasslands are very good place of conservation. Southern India forms the important genetic resource centre for many grass crops which includes cereals, millets, sugarcane, lemon grass, ginger grass etc. farmers in Maharastra are also conserving PGR and maintaining Biodiversity Register of the grassland species under guidance of Samvedana. “Community based conservation” and “peoples’ participation” have become part of the conventional rhetoric. Wealth of segregating breeding population also need to be conserved. The grasses or other species in grasslands are growing in highly diverse and harsh condition. These are harbouring genes for tolerance to many abiotic stresses such as light, heat and salinity/alkalinity. Hence, this wide variability, if conserved suitably, can prove to be resource to address climate change issue.

Indian Grassland Biodiversity Based on reconnaissance survey, India is reported to have five grass covers identified i.e. Indian sub-continent is one of the world’s Sehima – Dichanthium type, Dichanthium- mega centers of crop origins and plant diversity Cenchrus-Lasiurus type, Phragmites-Saccharum- as it represents a wide spectrum of eco-climate. Imperata type, Themeda-Arundinella type, and Genetic diversity comprising native species Temperate Alpine type. These naturally and land-races occurs more in Western Ghats, maintained grasslands are beautiful example Deccan Plateau, Central India, North Western of conserving large number of genera Himalayas and North Eastern Hills. India has represented by various species and genotypes. 141 endemic genera belonging to 47 families In fact, there have been almost nil human of higher plants. Of the 4200 endemic species, interference in terms of selection pressure, Himalaya accounts for 2532 species, followed hence, the biodiversity is well conserved in by peninsular region (1788 species ) and these grazing lands. Andaman and Nicobar islands (185 species). The Sehima-Dichanthium grass cover, lying India possess 166 species of agri-horticultural approx between 8o and 28oN and 68o and 87o crops and 324 species of wild relatives. It also E, is represented by perennial grasses viz. possesses rich genetic diversity with regard to Dichanthium annulatum, Sehima nervosum, native grasses and legumes. There are reports Bothriochloa pertusa, Chrysopogon fulvus, of 245 genera and 1256 species of Gramineae, Heteropogon contortus, Iseilema laxum, Themeda of which about 21 genera and 139 species are triandra, Cynodon dactylon, Aristida setacea, endemic. One third of Indian grasses are Cymbopogon, Apluda mutica, Bothriochloa considered to have fodder value. Most of the intermedia, Arundinella nepalensis, Desmostachya grasses belong to the tribes Andropogoneae (30 bipinnata, Eragrostis and Eragrostiella spp. %), Paniceae (15 %), and Eragrosteae (9 %). Dichanthium-Cenchrus-Lasiurus grass cover, Similarly, out of about 400 species of 60 genera between 23 o and 32o N and 68o and 80oE, is of Leguminosae, 21 genera are reported to be mingled with grass species such as Cenchrus useful as forage. Some of the genera exhibiting ciliaris, C. setigerus, D. annulatum, Cymbopogon wide forage biodiversity includes legumes like jawarancusa, Cynodon dactylon, Eleusine Desmodium, Lablab, Stylosanthes, Vigna, compressa, Laesiurus sindicus Sporobolus Macroptelium, Centrosema and grasses like marginatus, Dactyloctenium sindicum, Bothriochloa, Dichanthium, Cynodon, Panicum, Desmostachya bipinnata etc. Important associate Pennisetum, Cenchrus, Lasiurus. species are: Chloris, Desmostachya, Heteropogon Proceedings of 23rd International Grassland Congress 2015-Keynote Lectures 319 Malaviya et al. contortus, Saccharum bengalense, Vitevaria security and ecosystem services that are facing zyzanioides, etc. Phragmites-Saccharum-Imperata Governments worldwide, need to understand grass cover, between 26o and 32oN and 74o to how the ecosystem works.
