MARQUEZ SANCHEZ, Fidel. Epistasis in maize synthetic varieties. Rev. fitotec. mex [online]. 2010, vol.33, n.spe4, pp.101-105. ISSN 0187-7380.

In a previous article the equations for estimating epistasis were developed for several populations frequently used in maize (Zea mays L.) breeding, and it was shown how this genetic phenomena acts according to the structure of the involved populations. Since synthetic maize varieties have a big potential to be utilized by marginalized farmers and are relatively easy to obtain, this article focuses on calculating the mean epistasis of a synthetic variety created from homozygous lines under the epistatic model.
