Abstract:

Oryza officinalis Wall accumulated abundant genetic diversity and contains a large number of important beneficial genes. The indistinct molecular genetics background of Oryza officinalis Wall and the low efficiency of conventional breeding were two obstacles on the utilization of Oryza officinalis Wall. By using transgenic technology to transfer large fragment to cultivated rice to buiding gene insertion mutant libraries and transformation-competent large fragment libraries of wild rice, these problem were resolved. In this paper the auther summaried the research of excellent genes in Oryza officinalis Wall and utilization of those genes
