Abstract
Extra-early quality protein maize (QPM) hybrids with combined tolerance to drought and low soil nitrogen (N) are crucial for reduced food insecurity and malnutrition in sub-Saharan Africa (SSA). Ninety six extra-early QPM single-crosses derived from 24 extra-early QPM inbreds using the North Carolina Design II plus four checks were evaluated under stress (drought and low-N) and non-stress environments in Nigeria, 2012 and 2013. The objectives were to (i) determine the gene action for grain yield and other agronomic traits in the QPM inbreds (ii) identify the best inbred testers across environments (iii) classify the inbreds into heterotic groups and (iv) evaluate the performance and stability of the hybrids. General combining ability (GCA) effects contributed more to the total variation among the hybrids for grain yield and most measured traits under each and across environments suggesting that additive gene effects were more important in the inheritance of the traits....
