Results Combined analyses for traits recorded under stressful and non-stressful conditions Highly significant (p < 0.001) differences were detected among environments, hybrids, and parental lines for grain yield (GY), days to anthesis (DA), days to silking (DS), plant height (PH), and ear height (EH) across Striga-infested ( Table 1 ), Striga non-infested ( Table 2 ), and combined drought and heat stress (DHS) ( Table 3 ) conditions.
