Abstract:Local(Hepu) wild rice with good adaptability and breeding materials IR2061,and IR611 were used to develop a series of elite lines by single crossing,multiple crossing,and thereafter by pedigree selection with many generations and many lines.A male sterile line Bo A was employed to testcross these elite lines,and one of these lines No.679 was the best in terms of its hybrid when crossed with the male sterile line Bo A,and this hybrid was named Boyou 679.This hybrid was evaluated in Guangxi new variety test and production test in 2003,2004 respectively.With the result of high yield,good quality,and good resistance capability,it was certified by Guangxi,and appointed to be one of the leading varieties in Guangxi in January 2005,and was being planted on a large scale in the Guangxi,Guangdong,and Hainan provinces.
Keywords:wild rice  wild hybridization  pedigree breeding  restore line  restorability test
