The positive resistance effects at qSTV3,qSTV7 and qSTV11 were from IR24.A graphical genotype analysis of the CSSL population indicated that the IR24-derived segments presented in five lines with QTL conferring rice stripe resistance.

• 采用图示基因型比较法,在CSSL群体中将4个抗条纹叶枯病相关基因位点分别定位在染色体片段置换系CSSL4、L17、L39、L61、L62的IR24插入片段上。
