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
Breeding programs for acid-soil tolerance are desirable as a relatively inexpensive and permanent way for increasing maize (Zea mays L.) yield on these soils. Our objective was to compare the genetic effects controlling the expression of maize traits in acid and non-acid soils. Seven related and ...

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...
