Using sck transgenic rice, such as M81, R527, C162, Qiu B, D62B, and its controls as the materials, we investigated and identified their resistance to stem borer in the field. The results were showed as follows. Compared with the control, the resistant abilities to stem borer of all sck transgenic rice materials planted in paddy-field during early crops and late crops increased distinctly using dead heart plant index and white head plant index as identification indices. All of them had middle or high resistant abilities to stem borer, but all controls were middle sensitive or sensitive to stem borer. The results gained from dead heart plant index and white head plant index, early crops and late crops were similar. We can use dead heart plant index or white head plant index as identification index in early crops or late crops in stem borer resistance identification in the future.
