Landrace El Mota (EM) was selected by farmers for its adaptation to erratic rainfall, poor soil fertility and its high yield potential. However EM lacks resistance to Striga, which often results in major yield reduction. Natural resistance to Striga found in an African cultivar, SRN39 was introgressed into El Mota. A total of 103 BC2F3 introgression lines and two parental genotypes were tested in Niger for two consecutive seasons. Data on resistance to Striga and agronomic performance were recorded. The Striga count at 90 days after planting had homogeneous variance across years, heterogeneous variances among lines and the highest heritability. None of the introgression lines ranked as high in resistance as SRN39, but as many as 25 lines with the lowest Striga count had agronomic performances similar to El Mota. Laboratory assays revealed that the particular mechanism of resistance introgressed in the El Mota background was that of an incompatible reaction to Striga.
