| 摘 要： | 分析黑龙江寒地杂交水稻选育中存在的技术问题,指出其核心技术难点是耐冷性恢复系的选育。介绍自2006年起,耐冷性恢复系选育、高异交率不育系转育和强优势杂交组合配组的研究过程。针对在育种研究中发现的问题,设计黑龙江寒地三系杂交粳稻的穗粒结构指标,提出理想株叶形态的要求,并对黑龙江寒地杂交粳稻的耐冷性和稻瘟病抗性进行分析。结果表明,制约黑龙江杂交水稻发展的关键技术问题已得到较好的解决,开发应用前景广阔。

| Abstract: | The main technical problem of hybrid rice breeding in Heilongjiang cold region were analyzed.It was pointed out that the key problem is the breeding of cold tolerance restorer line.then,the research progress of cold tolerance restorer line,high outcrossing rate of CMS line,strong heterosis combination since 2006 were introduced.Accord to the problems in breeding research,the yield components of three line japonica hybrid rice in Hei long jiang cold region were designed,the demand for ideal plant morphology was put forward,and the cold tolerance and rice blast resistance were analyzed.The results showed that the main limited factors of hybrid rice breeding in Heilongjiang were resolved. |
