安徽省杂交粳稻研究回顾与展望

Review and Prospect of the Studies on Japonica Hybrid Rice in Anhui

回顾了 2 0余年来安徽省杂交粳稻育种与开发的历程 ,对育成有应用价值的BT型不育系、光敏核不育系、恢复系和杂交新组合 ,特别是推广百万亩以上的组合与超级稻组合的产量、抗性、米质作了简介 ,分析了阻碍我国杂交粳稻发展的瓶颈 ,提出了技术对策。

In the paper,the breeding and development of japonica hybrid rice in Anhui in the last more than 20 years were reviewed.The yield,resistance and grain quality of japonica hybrid rice combnetion,specially for these extended over more than 66.7 thousand hm2 and relevant cytoplasm-genetic male sterility (CMS) lines of BT-type, photo-sensitive genetic male sterile (PGMS) lines,restorer lines,with special commercial value were briefly introduced,and the technological countermeasure of future development was proposed.
