N2 - Genetic resources for food and agriculture play a crucial role in food security, nutrition and livelihoods and in the provision of environmental services (FAO, 2013). They are key components of sustainability, resilience and adaptability in production systems. These resources provide basic material for selection and improvement through breeding to ensure food security needs of the world’s rapidly rising population (Bansode et al., 2015). Plant genetic resources (PGR) represent the diverse gene pools including landraces, primitive cultivars, varieties of traditional agriculture, wild and weedy relatives of crop plants, etc (IPGRI, 1993). These resources have gained more importance in food security, but are under major threats. Increase in the level of non-natural greenhouse gases which are elements of climate change leads to a rise in earth’s temperature, resulting to consequences that include melting of glaciers; more precipitation; extreme weather events and the shifting of seasons. Climate change is one of the major threats to agricultural biodiversity, increasing genetic erosion of landraces and threatening wild species, including crop wild relatives (Jarvis et al., 2008). Losses of plant genetic resources due to climate change and bio-terrorism has resulted in major concerns about future food and nutrition security and, the valuable gene pool is being lost day-by-day due to other threats such as narrow genetic base resulting from directional selection, deforestation, industrialization, biotic or abiotic stresses (Bansode et al., 2015). Climate change has cause shifts in the distribution of land areas suitable for the cultivation of a wide range of crops, with a general trend towards the loss of cropping areas in sub-Saharan Africa, the Caribbean, India and other continents of the world including Europe. The increased rate of global population and income growth combined with climate change, threatens food security everywhere. Higher temperature and changes in precipitation patterns eventually reduce yields of desirable crops while encouraging weed and pest infestation (Frumhoff et al., 2007; Wolfe et al., 2008).
