两系杂交粳稻育种研究进展与展望
Research Progress and Prospects of Two-Line Hybrid Japonica Rice Breeding
摘要
Abstract
Two-line hybrid rice is of great significance in harnessing the heterosis of rice and ensuring China's food security.By May 2025,there were only 10 national approved varieties of two-line hybrid japonica rice,accounting for just 0.23%of the national approved rice varieties during same the period.Based on the current development status of two-line hybrid japonica rice,this paper summarized the progress in the breeding of japonica dual-purpose genic male sterile lines and the genetic loci and mechanisms of photo-thermo-sensitive male sterility in japonica dual-purpose genic male sterile lines,and conducted an in-depth analysis of the reasons why its development lags far behind that of two-line hybrid indica rice.Furthermore,it puts forward targeted countermeasures for future development,aiming to provide valuable suggestions and references for promoting the breeding and application of two-line hybrid japonica rice.关键词
