The results demonstrated that the Basta-positive rice plants were highly resistant to stripe stem borer (Chilo sup-pressalis) both in the laboratory and field tests. Both cryIA (b) and bar genes were expressed and co-inherited in both self ing and crossing progenies. Mendelian segregation of the marker gene bar was observed in F2 and BC1 progenies. The results implicates that it is possible to transfer cryIA (b) gene into other cultivated varieties through crosses and back crosses.展开更多
