crop in Eritrea. This weed has a complex mode of infestation that adapts to many hosts and environments,&#13;
complicating conventional breeding for resistance, which is the only form of crop improvement&#13;
available to Eritrean breeders, but has failed. This study aimed at improving resistance against this parasite&#13;
by transferring 5 Striga resistant Quantitative Trait Loci (QTLs) from resistance donor N13 to Striga&#13;
susceptible Farmer-Preferred Sorghum Variety (FPSV) Hugurtay from Eritrea. The method involved backcrossing&#13;
using marker-assisted selection (MAS) and evaluation of the best introgressed lines for Striga&#13;
resistance in artificially infested fields. Foreground selection was performed with up to 11 polymorphic&#13;
simple sequence repeat (SSR) markers linked to Striga resistance QTLs, while background selection was&#13;
conducted in the BC3F2 generation with 27 polymorphic unlinked SSR markers to identify the best recovery&#13;
of the recurrent parent (RP) genetic background. Out of 84 BC3F3 lines, L2P3-B, L1P5-A and L2P5P35&#13;
performed best with respect to both grain yield and reduced Striga infestation. These lines were more&#13;
resistant to Striga than Hugurtay, but less resistant than N13. The three lines yielded twice as much as N13,&#13;
with Area Under Striga Number Progression Curve (AUSNPC) values on average 18% higher than that of&#13;
N13 and 38% lower than that of Hugurtay. This suggests that the introgressed QTLs conferred significant&#13;
Striga resistance and yield advantage to these BC3F3 backcross progenies under Striga pressure. These&#13;
lines have good potential for future release and demonstrate that when MAS is available to conventional&#13;
breeders, even in countries with no genotyping facilities, it is a useful tool for enhancement, expediency&#13;
and precision in crop improvement.</mods:abstract><mods:classification authority="lcc">Sorghum</mods:classification><mods:classification authority="lcc">Entomology</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2015</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Elsevier</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
