Acid soils severely reduce maize (Zea mays L.) yield in the tropics. Breeding for tolerance to soil acidity provides a permanent, environmentally friendly, and inexpensive solution to the problem. This study was carried out to determine the relative importance of additive, dominant, and epistatic...

Additive, dominant, and epistatic effects for maize grain yield in acid and non-acid soils
There is a limited knowledge on the inheritance of traits with agronomic relevance in cassava. A diallel study among 10 parental clones was conducted in the acid-soils environment in the eastern savannas of Colombia. Thirty clones were obtained for each F1 cross. Each clone was represented by six...

Desarrollo de una técnica para evaluar la tolerancia en maíz a suelos ácidos y estudio de su herencia
Cinco poblaciones de maíz tropical del CIMMYT están siendo mejoradas para tolerancia a suelos ácidos mediante selección recurrente de hermanos completos. Se evaluaron tres ciclos de selección en un diseño de parcela dividida, con número variable de repeticiones, en cinco am...

Tolerancia a suelos ácidos en poblaciones tropicales de maíz del CIMMYT
Little is known about the inheritance of agronomic traits in cassava, or on the relative importance of epistasis for most crops. A group of 10 clones, adapted to the acid-soils environment was used as parents in a diallel study. Thirty genotypes were obtained from each F1 cross and cloned. Each c...
