摘要

Rice is a vital crop in Nepal and globally, with the Federal Government of Nepal emphasizing its economic importance in the 16th Five-Year Plan. However, local rice cultivars in Nepal face a serious threat from rice blast disease, caused by the fungus Pyricularia oryzae, which severely reduces yields. Moreover, this threat jeopardizes many indigenous rice cultivars susceptible to the disease, making their preservation urgent. Globally, genome editing tools are gaining acceptance for their accelerated breeding potential and produce plants comparable to those developed through conventional methods. However, Nepal has been slow in adopting this tool in both research and commercialization. Applying genome editing to target susceptible genes and negative regulators of blast resistance offers great potential for improving local rice cultivars. Such approaches can also reduce chemical fungicide use and support sustainable, organic farming systems. Continuous advancements in genome editing tools and strategies are further enhancing their efficiency. This review highlights the significance, current status, and prospects of accelerated rice breeding in Nepal using genome editing technologies.
