  abstract = {{S}triga hermonthica ({D}el.) {B}enth. is a persistent threat to pearl millet [{C}enchrus americanus ({L}) {M}orrone, comb. nov.] production, especially in {W}est {A}frica. {T}his study aimed at evaluating the response of a diversified pearl millet genepool to five cycles of recurrent selection targeting {S}triga resistance and panicle yield, and to a lesser extent downy mildew [{S}clerospora graminicola ({S}acc.) {J}. {S}chroet.] resistance. {T}wo-hundred full-sib families ({FS}) representing the {C}-5 selection cycle were evaluated together with the genepool parental landraces, experimental varieties derived from previous cycles and local checks in {S}triga-infested fields at {S}adore ({N}iger) and {C}inzana ({M}ali). {S}ubstantial and mostly significant selection progress could be documented. {T}he accumulated percentage gain from selection amounted to 51%/1% lower {S}triga infestation (measured by area under {S}triga number progress curve, {ASNPC}), 46%/62% lower downy mildew incidence, and 49%/31% higher panicle yield of the {C}-5-{FS} compared to the mean of the genepool parents at {S}adore/{C}inzana, respectively. {E}xperimental varieties selected from previous cycles also revealed lower {ASNPC} and mostly higher yield compared to genepool parents at their selection sites. {S}ignificant genetic variation among the {C}-5-{FS} and operative heritabilities of 76% ({C}inzana), 84% ({S}adore) and 34% (combined across locations) for {ASNPC} will enable continued selection gain for {S}triga resistance. {H}igh genotype x environment interaction variances for all target traits suggest that different experimental varieties need to be extracted from the genepool for different sites. {T}he genepool-derived varieties will be further validated on-farm and are expected to contribute to integrated {S}triga control in pearl millet in {W}est {A}frica.},
