Genetic Variability of Rice

Rice is most important cereal and stable food crops of Nepal and fulfilled about 50- 80% of caloric requirement of Nepalese people. It is important cereal crop, both in terms of cultivated area, production and supporting livelihoods. Most of the people of Nepal are living in rural area; face poverty, hunger and inadequate rainfall pattern which leads to food insecurity. Population is increasing, demands more food and to feed increasing population, agriculture production should increases per unit area. Most of the the irrigated and plan cultivable land in Nepal are converting into forest of concert so, due to this reason research was carried out to explore the ideas of genetic variability of rainfed rice to determine the best rice genotype in rainfed condition, which helps in some extend to meet food demand and to tolerate with irregular rainfall pattern in Nepal.
