The new gene transferring rice is named Genetic Engineered Rice (GER) line. The team put dry embryo of rice cultivar Xiangzaoxian 8 in the solution containing maize DNA using a modified method of embryo soaking to introduce the exotic DNA into the rice embryo. By selections through successive generation, promising rice lines were finally developed from progenies having required variations. DNA molecular test showed that the lines have already got some maize DNA fragments. The line GER-1 is of the most productive among the new rice lines.
