摘要
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.关键词
