Contribution of maternal effects to grain yield and other traits for some white promising maize (Zea mays L.) hybrids [electronic resource].

Includes reference.

The differential expression of maternal effects could be an important source of fifteen variation under some environmental conditions. Nine white promising lines were developed at maize breeding nursery of Nubaria Nonstematic crosses and their reciprocals were done to produce eighteen promising single-cross hybrids. The resultant crosses and the check hybrid. SC.10. were evaluated in replicated yield trials at three errvironment3 in 2007 season. The objectives of this study were to (i) investigate the relative importance of maternal effects on grain yield and other traits of some promising maize hybrids and (ii) identify new maize hybrids with superior grain yield across different errvironments.
