湖南省两系法杂交水稻研究开发工作,由于各级领导重视和科研、推广部门的紧密协作攻关,进展顺利,成效显著。现已育成一批可供生产上应用的低温敏核不育系,配制了“培两优特青”等一批强优组合,并测交出了比三系杂交水稻增产15％以上,且早熟、优质的品种间 Hunan Province, two lines of hybrid rice research and development work, due to the leadership at all levels attach importance to research and promotion departments to work closely collaborative research, progressing smoothly, with remarkable results. Now a batch of low temperature sensitive genic male sterile lines that have been bred for production have been bred and a batch of strong combination such as “Peilian Youteng” has been bred and tested, yielding more than 15% more yield than three-line hybrid rice Early maturity, high-quality varieties
