Combining ability of highland adapted maize (Zea mays L.) inbred lines for grain yield and yield related traits under optimum and low nitrogen conditions

Maize is staple cereal crop in Ethiopia despite the fact that its production is constrained by nitrogen deficiency due to the high cost of fertilizer, and risks of drought. Therefore, development of maize varieties for low nitrogen might be one of the options to overcome the problem. The objective of this study was to estimate combining ability of highland maize inbred lines for yield and yield related traits under low...
