Maize is one of the most important grain and forage plants that has a unique role in the food and feed, especially poultry feed. To study the genetic effects, genes act and identify the best hybrid combination for morphological traits, experiment was carried out in diallel cross layout using 19 parents at Gorgan Agricultural Research Station, Iran in 2013. The progenies were planted in three re...

The line value of a genotype is defined as the expected value of all lines that can be derived from this genotype. Specific genetic effects are defined for this value: only additive and additive by additive epistatic effects are necessary. There is no dominance effect for such a value. A general expression for the covariances between related lines is given. From a design with several lines per ...
