Populations o f pearl millet and sorghum are being developed and improved fo r a
variety o f purposes. In this paper, we present a global review o f current populations,
their composition, and methods for improvement. The potential impact o f these programs
is indicated by recent results regarding responses to recurrent selection and the
linkages ofpopulation improvement with development o f lines and varieties in these two
crops. Recent research on generating interpool populations and modeling responses to
alternative recurrent selection methods are presented fo r population improvement o f
