Identification of quantitative trait loci under drought conditions in tropical maize 1 flowering parameters and the anthesis-silking interval. In an increase in the length of the anthesis-silking interval (asi) and in a decrease in grain yield selection for re- duced asi in. In drought the anthesis-silking interval is linked to silk growth because the rates of both silk elongation and cell division are reduced by water deficit.
