Abstract: An rice population consisting of 90 F3 lines from TN1/Guiyigu was employed to analyze linkage between DNA markers and a new gene Wbph6(t) conferring resistance to the whitebacked planthopper. Using the mapping approach of bulked extremes and recessive class, Wbph6(t) was mapped onto the short arm of chromosome 11 of rice, with a genetic distance of 21.2 cM to SSLP marker RM167.

Key words: rice, whitebacked planthopper, resistance, gene mapping, simple sequence length polymorphism

摘要： 应用由90个株系组成的TN1/鬼衣谷F3群体，分析了水稻抗白背飞虱新基因Wbph6 (t)与DNA标记的连锁关系。应用隐性极端群体法，将[WTBX][STBX]Wbph6[WTBZ][STBZ](t)定位于第11染色体短臂，与SSLP 标记RM167的遗传距离为21.2 cM。
