520			_aSelection for grain yield under drought conditions has often been considered ineffident because of low heritability, especially as yield decreases. Selection for secondary traits correlated to grain yield and having relatively high heritabilities may increase selection effidency. Anthesis silking interval (ASI) is a precise secondary trait (Edmeades et al. 1999). With the development of molecular markers, it is possible to identify major quantitative trait loci (QTL) regulating specific drought responses, and thus provide an effident way to improve drought tolerance in maize germplasm (Veldboom et al.19%). In this study, the QTL lod conferring the expression of ASI and yield components were characterized, and the resulting information was adopted to improve grain yield under drought conditions.
