| Summary: | Nepal is an agrarian-based country with most of the population engaged in the agriculture sector for their livelihood. Nepal, with its numerous agroecological zones, is moving from subsistence to commercial agriculture to reduce poverty, provide food security, and improve economic growth. Crop breeding programs were initiated in 1951 A.D. in Nepal to focus on the development of varieties for cereal crops, but most of the farmers are still based on their low-yielding traditional varieties. Hybrid varieties, developed by the cross-pollination between different plant varieties, play a vital part in this change by demonstrating heterosis, resulting in increased yields, resilience to biotic and abiotic challenges, and consistency in agronomic features. Hybrid maize and rice exhibit considerable potential to increase productivity, enhance smallholder farmers’ earnings, and strengthen food security via efficient farming methods and mechanization. Despite these advantages, Nepal’s dependency on imported hybrid seeds highlights issues such as expensive fertilizer and pesticide input costs, limited local production capacity, and concerns about genetic erosion. Nepal mostly imports hybrid seeds, and due to the rising demand, the country allocates substantial financial resources for their importation. In Nepal, the low quality of hybrid seed imported by different seed agencies and companies causes yield loss, more expenditure by farmers for purchasing seed, and a higher incidence of insect, pest, and disease. The Nepalese government should place emphasis on conducting research on hybrid seed development for cereal crops as well as vegetable seeds in collaboration with the private sector. |
