Resistance to BLS of each line in the population was tested in both 1996 and 1997. The methods of t test, composite interval mapping and multiple trait composite interval mapping were used to map genes(QTLs) underlying resistance to BLS.

• 1996和1997连续两年对该群体进行了细条病抗性鉴定。 采用t测验法、复合区间定位法及多性状复合区间定位法对细条病抗性基因（QTL）进行了定位分析。
