摘　　要：用转sck基因的M81、R527、C162、秋B、D62B系列水稻及对照,进行了田间抗三化螟性调查和评价。结果表明:与对照相比,用枯心指数和白穗指数作评价指标,所有转sck水稻在早造和晚造大田种植中对三化螟抗性均明显提高,达中抗以上,而对照均为中感或感级。而且评价指标枯心指数和白穗指数之间,早造和晚造之间所得结果较一致,在以后抗螟虫鉴定中可考虑选用枯心指数或白穗指数作指标,在早造或晚造进行。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.
