简介：Bt5198，包含Bt基因的一根新米饭restorer线，与BtMinghui63从精英restorer线Chenghui177的十字和回交被开发，一根转基因的Btrestorer线。生来的线用PCR扩大，测试纸评估，在实验室的昆虫抵抗评估和稻地被评估，大米强风抵抗的托儿所评估和农学的特点的家谱选择。当米饭灰煤杆在实验室与有斑纹的茎borer(SSB)的鸡蛋被接种时，Bt5198和BtMinghui63上的幼虫的死亡是100%。Bt5198在地条件下面对SSB和黄茎borer(YSB)是高度抵抗的。F1混血儿源于Bt5198和四细胞质的男性无菌(厘米)线对SSB和YSB也高度抵抗并且有重要杂种优势。米饭强风抵抗的二年的评估BtMinghui63比那些更好证实到叶的Bt5198的抵抗层次爆炸，颈强风类似于Chenghui177并且显著地的那些。Bt5198的种子萌芽能力和花粉产量与Chenghui177是类似的，建议进新restorer线的Bt基因的介绍没有种子活力或种子生产的收益上的重要效果。识别Bt基因的存在，把测试纸检查与昆虫抵抗的评估相结合是有效的，在实验室并且在地条件下面。

简介：YuetaiA的种子样品，一种Honglian(HL)类型细胞质的男性无菌(厘米)在混合大米的线被调查估计种子纯净并且由在南京，江苏省和Lingshui模仿生物沾染物到YuetaiA分析离开类型植物的原因，海南省在20042006期间。YuetaiA的种子杂质主要源于在生物污染以后然而并非从它的绝育unstability恢复富饶基因(Rf)的基因飘移。十根维护者线，五根restorer线和三thermo敏感的遗传因子的男性，无菌的线在学习使用了的所有能传花粉给生产F1的YuetaiA和YuetaiB种，直接或间接地导致漂流进YuetaiA并且产生iso细胞质恢复产生的Rf基因。而且，高outcrossing率和有许多变化的YuetaiA的类似的标题日期容易在米饭生产力量使用了在生物污染的结果。在移开所有植物，Rf基因在YuetaiA混合了并且阻止Rf基因漂流进YuetaiA以后，YuetaiA和YuetaiB的种子纯净被提起了到100%。
