The GGE biplot tool has potential for determining combining ability effects, identifying distinct heterotic groups and efficient testers in a line × tester study. However, its use for such analysis has not been adequately explored. The objectives of this study were to (i) assess combining ability...

Biplot analysis of line X tester data of maize (Zea mays L.) inbred lines under stress and nonstress environments
Appropriate testers are needed as well as information on heterotic patterns of tropical lowland early-maturing germplasm. Diallel crosses involving nine tropical early maturing maize (Zea mays L.) inbreds were evaluated at five locations in Nigeria from 2007 to 2009 under drought stress, when Str...

Biplot analysis of diallel crosses of early maturing tropical yellow maize inbreds in stress and nonstress environments
Climate change is expected to aggravate the effects of drought, heat and combined drought and heat stresses. An important step in developing ‘climate smart’ maize varieties is to identify germplasm with good levels of tolerance to the abiotic stresses. The primary objective of this study was to i...

Maize (Zea mays L.) is an important staple food crop in West and Central Africa(WCA). However, its production is constrained by drought. Knowledge andunderstanding of the genetics of hybrid performance under drought is invaluablein designing breeding strategies for improving maize yield. One hund...

Extra-early maize (Zea mays L) tolerant to low-N and drought could stabilize yields in sub-Saharan Africa. Studies were conducted under drought and low-N conditions in Nigeria for three years to determine the potential of 90 extra-early inbreds for hybrid production and evaluate the performance o...

Drought is a major constraint to maize production in West and Central Africa (WCA). Assessment of genetic gain from S1 recurrent selection under drought is crucial for the development of drought tolerance breeding strategies. In an early white population, 60 S1 families each derived from the base...

Maize (Zea mays L.) is the most important staple crop in West and Central Africa (WCA), but its production is severely constrained by low soil nitrogen (low N). Fifty-six extra-early open-pollinated maize cultivars developed during three breeding eras, 1995–2000, 2001–2006 and 2007–2012, were eva...
