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...

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 ...

Los cruzamientos dialelos de 12 padres contrastantes en la toma y uso de fósforo se evaluaron en dos niveles de fósforo (4 y 15 ppm) usando un dise o experimental de alpha lattice con tres repeticiones. Se usó el dise o genético propuesto por Hallauer y Miranda. En bajo y alto fósforo se encontra...
