Neglected, underutilized, and future smart crop species in Nepal

2019, Journal of Crop Improvement

Abstract

Nepal ranks 49th in the world for biodiversity richness. Among 577 cultivated species in Nepal, 484 are indigenous and 93 are introduced. About 85% of these cultivated crop species are neglected and underutilized. The use of landraces in research and breeding is only about 5%. Just three crops, viz., rice (Oryza sativa L.), wheat (Triticum aestivum L.), and maize (Zea mays L.), cover 83% of the total cultivated area. Monogenotyping (the use of genotypes containing genetic material from a single parent) field, kitchen, market, and food items have triggered new problems. In Nepal, neglected and underutilized species (NUS) are those crop species that are not included in formal research, education, and development. Future smart crops (FSCs) are NUS that are known for their high potential for food, nutritional security, and high adaptability to changing climate. FSCs have tremendous potential to contribute to food security, nutrition, dietary and culinary diversification, health, income generation, and are well adapted to marginal soils and harsh climatic conditions. To manage (conserve and utilize) all agricultural genetic resources, including NUS and FSC, 25 conservation methods, along with more than 30 good practices, have been practiced in Nepal. Many of the NUS have not been adequately studied for their nutritional value and adaptability to harsh environments. This paper provides current status and potential of NUS and FSCs for developing site-specific staple, nutritious, diversified products and climate-resilient varieties. This review also addresses the prospects of long-term conservation and sustainable agriculture systems in Nepal.
