Genetic erosion of crop diversity is reported worldwide. Many crop species, varieties or landraces are being lost (Brush 2000). Importance of plant genetic resources is recognized worldwide to cope up with the biotic and the abiotic stresses. Genetic erosion is the common threat to the sustainable use of plant genetic resources to meet the present needs and aspiration of future generations (Chang 1985). There are many examples of genetic erosion in Nepal, even though it is rich in agricultural biodiversity. There are 200 cultivated species, 500 wild edible plants and 120 cultivated plants species reported in Nepal (Upadhyay and Joshi 2003). Tauli, Marsi and Thapachinia, the popular rice varieties of Kathmandu valley are no longer available (Upadhyaya 1995).
