Heterosis and Combining Ability for Maize Adaptation to Tropical Acid Soils: Implications for Future Breeding Strategies

Soil acidity reduces maize (Zea mays L.) yields by up to 70% on 8 million hectares in developing countries. Several breeding programs have produced populations better adapted to these conditions. The objectives of this study were to evaluate these populations for both per se cultivation and the deve...
