N2  - Identification of a base maize population is a key decision in a maize breeding program. Desired base populations should have a high grain yield and broad genetic variability in addition to good agronomic traits and resistance to biotic stresses and tolerance of abiotic stresses. Prediction of the population mean is useful if the number of available composites is large, because otherwise a large amount of resources are needed for their estimation. There are different methods of predicting the population mean (Gardner and Lonnquist 1966; and others). The objective of this study was the estimation of population mean for grain yield and virus maize diseases of ten maize populations
