Combining ability of diverse maize inbred lines under Striga infestation in Nigeria and Benin por Yallou, C., Menkir, A., Adetimirin, Victor O., Kling, J.

“…The ten lines were crossed in a diallel fashion and the resulting 45 single-cross hybrids were evaluated under artificial striga infestation at two locations each in Nigeria and Republic of Benin for two years. The results showed that general combining ability (GCA) mean squares were much larger than those for specific combining ability (SCN for grain yield under Striga infestation, Striga damage symptom score, and numbers of emerged Striga plants, indicating that for these traits, additive genetic effects were more important than non-additive effects. …”
