The LOD score was 2.689.45.Three QTLs qGL-5,qGWt-1a and qGWt-1b were both detected under upland and lowland environments(common QTL). Two co-localized QTLs(qGL-1a and qGWt-1a,and qGL-1b and qGWt-1b) controlling GL and GW were detected.

• 其中控制粒长的qGL-5及控制粒重的qGWt-1 a和qGWt-1b在水、旱条件下均能检测到,在抗旱育种中可用于分子标记辅助选择籽粒性状。
