基因编辑及全基因组选择技术在水稻育种中的应用展望OACSTPCD

Rice is the main grain crop in China.Due to large population and limited land resources in China,rice breeding goals have long been yield oriented.Chinese researchers have continuously achieved breakthroughs in rice breeding technology,and the adoption of dwarf breeding and hybrid rice breeding technology has resulted in two significant leaps in rice yield in China.However,with the improvement of living standards and the increasing frequency of extreme weather events,higher demands have been placed on rice in terms of yield,quality,and resistance.At present,biotechnology is undergoing constant innovation,particularly with the rapid development of gene editing and genomic selection breeding technology.This progress is expected to provide robust support for the development of new rice varieties with high yield,superior quality,and resistance to multiple factors.It helps promote the green and sustainable development of rice production.This paper reviews the recent advancements in gene editing technology and genomic selection technology in rice breeding for high yield,superior quality,disease and insect resistance,stress tolerance,and heterosis.The goal is to provide breeding strategies for the efficient development of new varieties to meet demands.
